hoarseness. pressure upon scapula.

swelling of the feet. on rising, pains in the bones..

(After the erysipelatous swelling of the feet had disappeared, there set in an eye trouble, consisting of swelling of the upper and lower lid, especially violent in the morning, with burning and stinging pain, especially in the morning and evening, with redness of the lids, better in the middle of the day; in the evening great photophobia, so that the candlelight could not be endured; reading by the light was very difficult, as though there were a mist about the light and a red and green halo; thick, slimy discharge, with agglutination of the lids),.

Cough very violent, with lachrymation (twelfth and thirteenth days).

the cough continued during the succeeding days, after two days it was very violent, especially after laughter, with sticking pain below the angle of the scapula and in the middle of the sternum on coughing.

the cough was worse in the morning, with stitches in the chest, more in the middle of the sternum than at the sides, with stitches in the middle of the sternum on inspiration.

*with the morning cough there was a thick yellow expectoration.

during the day the expectoration was insignificant.

the morning cough occurred on rising from bed.

in the evening it occurred at 9 P.M., on going to bed, lasting from one-half to three-quarters of an hour, without expectoration and without pain.

nose very much stopped.

could not breathe through the nose.

this Influenzinum influenza continued several days, and after two days was associated *with difficulty of hearing, at times with ringing in the ears, with profuse white slimy discharge from the nose, cough diminished, thick yellow expectoration, cough and expectoration worse after rising, seldom in the evening and through the day (on account of this attack the proving was suspended),.

Painful drawing in the lower portion of the left ulna, frequently repeated during the forenoon.

afterwards a drawing pain in the upper part of the left ulna near the elbow, and also sudden stitches in the radius near the elbow.

also frequent sticking and tearing in the upper part of the forearm, at times the pain as a drawing tearing, frequently returning during the forenoon (thirty-second day),.

Tearing pain in the hips, extending along the outer side of the right leg to the knee, where there was a stitch, relieved while sitting, returning on moving about.

inability to walk on account of painful stiffness of the knee.

after half an hour the sticking and tension occurred in the second phalanges of the fingers of the left hand (seventh day),.

Loss of appetite. pale, suffering expression.

every morning perspiration, which sometimes was very profuse.

heaviness and weariness of the lower extremities, that frequently obliged her to lie down.

nausea. chilliness every evening before going to sleep.

sticking pains here and there, in the sides of the chest, in the abdomen, limbs, at times so violent that she started up in fright.

pain beneath the sternum on inspiration.

itching on the arms and lower extremities, with small pimples,.

In the evening, after lying down (and slumbering), he began unconsciously to thrash about with the hands and feet and to jerk, with closed eyes and loud snoring (without screaming).

froth oozed from the mouth, after which he lay motionless, as if dead, and when one attempted to rouse him, he was quite stiff, then opened his eyes, that were fixed, and began to mumble (an epileptic attack?), (after sixteen days),.

Great coldness of the whole left side of the body, followed by frequent slumbering and starting up, as if she would go away without knowing whither, then she begins to lose consciousness, speaks unintelligibly, recognizes no one, and becomes so weak that she cannot turn over alone.

after this violent convulsions, with staring look, distortion of the eyes, twitching of the lips, lolling of the tongue, stretching and distortion of the head and limbs, lasting a quarter of an hour, followed by frightful roaring, dropping of tears from the eyes, frothing at the mouth.

after this warm perspiration over the whole body, free respiration, slumber, and after several hours gradual return of consciousness and speech (after forty-six hours),.

Imperfect assimilation and consequent defective nutrition. It goes further and produces neurasthenic states in consequence, and increased susceptibility to nervous stimuli and exaggerated reflexes. Diseases of bones, caries and necrosis. Silicea can stimulate the organism to re-absorb fibrotic conditions and scar-tissue. In phthisis must be used with care, for here it may cause the absorption of scar-tissue, liberate the disease, walled in, to new activities ( J. Weir.) Organic changes; it is deep and slow in action. Periodical states; abscesses, quinsy, headaches, spasms, epilepsy, feeling of coldness before an attack. Keloid growth.

it corresponds to the chronic form of such diseases as Pulsatilla Puls. cures when acute Rush of blood to the head, especially to the right temple and vertex.

headache everyday. photophobia.

lachrymation. loss of taste.

aversion to fat food with rancid or oily taste in mouth, &c. The symptoms of Sil. differ from those of Pulsatilla Puls. in being more constant, more deep-seated, and lasting longer.

for instance, the mucous secretions of Pulsatilla Puls. become easily purulent under the action of Sil. Teste points out that Pulsatilla Puls. flourishes best on sandy soils (as Belladonna Bell. does on calcareous soils). Schüssler, who was a homoeopathist before he was a Biochemist, describes the sphere of Sil. from the Tissue-Remedy point of view as follows "Silicic Acid is a constituent of the cells of the connective tissue, of the epidermis, the hair and the nails.

Sil. may also cause the absorption through the lymphatics of an effusion of blood in any tissue. If the reabsorption of a sero-albuminous exudation in a serous sac cannot be effected through Calc Carb Calc. Phosphorus phos., then Sil. may be used.

for the delay in the absorption may also be caused by deficiency of Sil. in the subserous connective tissue.

When a number of cells in the connective tissue are gradually deprived of Sil., they become atrophied. Such a disease is by no means rare in the external meatus auditorious with old people. The meatus in such a case is dry and enlarged," (Schüssler adds that he generally gives the 12x trituration.) The indications of Schüssler correspond so exactly with those already pointed out by Hahnemann that we are left in doubt as to how much he was indebted to Hahnemann for his facts and how much to his own theories. Be that as it may, the relation of Sil. to the connective tissues is a very real one. Sil. is a great evacuant. Sil. produced in the provings sensation of "splinter in the finger," of "a pin in the throat," and whenever foreign bodies have became embeded in the tissues.

or whenever portions of the tissues have become necrosed and quasi-foreign, Sil. will set up suppuration in the vicinity and bring about their expulsion. (It is this property which makes it necessary sometimes to use Sil. with caution; if there are deposits which have became encysted and so far rendered harmless, the administration of Sil. might set up suppurative action, to the risk of the patient's life.) Sil. both matures abscesses and reduces excessive suppuration. It will also resolve indurations left after suppuration.

this has been particularly noted in the case of tonsils which refuse to heal after the pus has been evacuated, and in abscesses which leave sinuses and fistulae. Sil. affects the nails, cripples them, and produces inflammation around and under them. "Sensation as if the finger-tips were suppurating" is one of the symptoms which led to its use in such cases. Sil. causes inflammation, swelling and suppuration of all the lymphatic glands and also the glands of the skin. The skin is unhealthy and every little injury ulcerates. Hands and feet are sweaty, and the sweat is generally offensive. The feet may give off an intolerable odour without any sweat. The head sweats, and this may be offensive. Sil. corresponds perfectly to many cases of rickets children with large heads.

Open fontanelles and sutures.

much sweating about the head, which must be kept warm.

distended abdomen. weak ankles.

slow in learning to walk. This constitutes type No. 1, to which Sil. is particularly suited. It is also suited to (2) Nervous, irritable persons, with dry skin, profuse saliva, diarrhoea, night-sweats. (3) Weakly persons, fine skin, pale face, light complexion.

lax muscles. (4) Constitutions which suffer from deficient nutrition due to lack of assimilating power.

oversensitive physically and mentally. (5) Scrofulous children who have worm diseases during dentition. (6) Stonecutters' ailments (chest affections and total loss of strength.).

The action of Sil. on the connective tissues may end in new growth as well as in suppuration and ulceration. It has a specific relation to scarred tissue.

and I have cured with it a case of recurrent cheloid Eleanor W., 14, had a growth on left temple. Five months before she had been an inmate in St. Bartholomew's Hospital, and had had a tumour removed from the spot, the tumour having existed for two years. A month after the operation a new growth appeared on the scar. Two months later this was removed. But it rapidly recurred, and when I saw her there was a linear elevation an inch long, three lines wide, and raised about two lines. It was red, shiny, and slightly nodulated.

was tender to touch and the seat of Shooting pain. Before the first operation there had been no pain and no discoloration of the skin. Hahnemann gives this symptom in the proving of Sil. "Stitching, aching pain in the spot where an ulcer had been formerly on the leg." Sil. 3 gr. iii., night and morning, was prescribed. There was no further increase in the size of the growth, though it was still painful, the pain being apparently somewhat increased. In three months there was evident diminution in size, and from that time the pain began to diminish. In seven months the growth had entirely disappeared.

The sensitiveness of Sil. is one of its keynotes, and an over-susceptibility to nervous stimuli is a frequent accompaniment of conditions requiring Sil.

The surface is tender and the least touch is painful.

The senses are morbidly keen.

Brain and spine cannot bear even ordinary vibrations.

Silicea condition may be caused by losses of fluids as in spermatorrhoea; by over-worked brain.

Sil. causes tendency to paralysis and paralytic weakness from defective nutrition of nerves of brain and spinal cord.

Constipation is often an accompaniment of these conditions.

There may be epileptic convulsions.

These have a well-marked course, starting from the solar plexus; are agg. at full and new moon; and agg. from any overstrain of mind or emotions.

Sil. is indicated in locomotor ataxy when the fingers feel stiff with loss of power in them.

There is spinal irritation.

The neck is stiff causing headache.

The small of the back aches as if beaten.

The part of the body lain on goes to sleep.

The headaches of Sil. present one of the grand characteristics of the remedy.

They are of the chronic kind, and may owe their origin to some severe disease of youth.

They ascend from the nape of the neck to the vertex, as if coining from the spine, and locate in one eye, especially the right; agg. from draught of air or uncovering head; amel. pressure and wrapping head up warmly; amel. profuse urination.

The vertigo of Sil. in the same way ascends from the back of the neck; as if one would fall forward (sometimes backward); agg. looking up; closing eyes; lying on left side.

The sensitiveness of Sil. comes out in the mental symptoms "Sensitive to noise.

and anxiety therefrom." "Sensitive, weeping mood." "Yielding, faint-hearted." "Children become obstinate, headstrong.

cry when kindly spoken to." A curious symptom and one of great value is this "Fixed ideas the patients thinks only of pins, fears them, searches for them, and counts them carefully." This symptom enabled me to make a rapid cure of post-influenzal insanity in the case of a man of bad family history, one of whose sisters had become insane and had drowned herself, another sister being affected with lupus.

The patient's wife told me one morning that he had "been looking everywhere for pins." Sil. 30 rapidly put an end to the search and restored the patient to his senses.

Sil. has another link with insanity in its aggravation at the moon's phases epilepsy and sleep walking are agg. at the new and full moon.

The Sil. patient likes to be magnetised, and is amel. by it.

Silicea is related to the persistent want of vital heat which characterises the Sil. condition; even exercise will not get up any warmth.

The constipation of Sil. is characteristic.

The stool is difficult as from inactivity of rectum; with great straining as if rectum was paralysed; when partly expelled recedes again.

Faeces remain a long time in rectum.

Rushmore (H. P., xii. 530) verified a peculiar symptom of Sil. in a lady suffering from scirrhus of left breast.

She had a feeling of dryness in her finger-tips, as if made of paper; at night. Antimonium Tartaricum Ant. t. and Sil. have this symptom, but only Sil. in afternoon.

Sil. removed this and took away sharp, stinging pains in the tumour as well.

The action of Silica is slow. In the proving, it takes a long time to develop the symptoms. It is, therefore, suited to complaints that develop slowly.

At certain times of the year and under certain circumstances peculiar symptoms will come out.

They may stay with the prover the balance of his life. Such are the long-acting, deep-acting remedies.

they are capable of going so thoroughly into the vital order that hereditary disturbances are routed out. The Silica patient is chilly.

his symptoms are developed in cold, damp weather, though often better in cold, dry weather.

symptoms come out after a bath.

The patient lacks stamina. What Silica is to the stalk of, grain in the field, it is to the human mind. Take the glossy, stiff, outer covering of a stalk of grain and examine it, and you will realize with what firmness it supports the head of grain until it ripens.

there is a gradual deposit of Silica in it to give it stamina. So it is with the mind.

when the mind needs Silica it is in a state of weakness, embarrassment, dread, a state of yielding.

If you should listen to the description of this state by a prominent clergyman, or a lawyer, or a man in the habit of appearing in public with self-confidence, firmness and fullness of thought and speech, he would tell you he had come to a state where he dreads to appear in public, he feels his own selfhood so that he cannot enter into his subject, he dreads it, he fears that he will fail, his mind will not work, he is worn out by prolonged efforts at mental work.

But he will say that when he forces himself into the harness he can go on with ease, his usual self-command returns to him and he does well; he does his work with promptness, fullness, and accuracy. The peculiar Silica state is found in the dread of failure.

If he has any unusual mental task to perform, he fears he will make a failure of it, yet he does it well. This is the early state; of course there comes a time when he cannot perform the work with accuracy and still he may need Silica

Another case is illustrated in a young man who has studied for years and is now nearing the end of his course. He dreads the final examinations but he goes through them all right, then a fatigue comes upon him and for years he is unable to enter his profession. He has this dread of undertaking anything.

Religious melancholy, sadness, irritability, despondency. Lycopodium Lyc is stupid, the dread of undertaking any thing in from a general knowledge of inability. In Silica it is imaginary.

Silica is not suitable for the irritability and nervous exhaustion coming on from business brain-fag, but more for such brain-fag as belongs to professional men, students, lawyers, clergymen. A lawyer says,

"I have never been myself since that John Doe case"

He went through a prolonged effort and sleepless nights followed. Silica restores the brain.

It acts upon constitutions that are sluggish and inflames fibrous deposits about old imbedded missiles. Slow nutrition; if the individual receives a slight injury it suppurates and the cicatrix indurates, is hard and nodular.

Along the track of a knife-cut, is a fibrinous deposit due to inferior and slow nutrition. An old ulcer heals with induration. Where cicatricial tissue forms, it is indurated, shiny, glassy. If Silica is given in such cases, it will throw out abscesses in these cicatrices and open them out. It will open up old ulcers and heal them with a normal cicatrix.

In ordinary people if a splinter lodges in the tissues, a suppuration will slough it out, but in these feeble constitutions a plastic deposit takes place about it and it remains. This is not the highest state of order. Suppuration takes place about a bullet and pushes it out, that is the best state that can be asked for.

Silica, therefore, hastens the formation of abscesses and boils. It suppurates out old wens and indurated tumors. It has cured recurrent fibroids and old indurated tumors.

It there is a deposit of tubercle in the lungs, Silica establishes ail inflammation and throws it out, and if the whole lung be tubercular a general suppurative pneumonia will be the result.

hence, the danger of giving such remedies and the danger of repeating them in advanced stage of phthisis. Not only Silica but many other remedies have the power to suppurate out deposits, the result of poor nutrition.

Warty growths on the skin, moist eruptions, pimples, pustules, abscesses. Suppurating cavities. It establishes healing in old fistulous openings with indurated margins. Catarrhal suppurations; copious muco-purulent discharge from the eyes, nose, ears, chest, vagina, etc.

Suppression Complaints from the suppression of discharges; suppressed sweat.

These suppressions produce a state in the economy that threatens what little order is left. An offensive foot-sweat ceases after getting the feet wet, and is followed by chills and violent complaints.

Silica cures long lasting foot-sweat when the symptoms agree, or complaints that have lasted since the suppression of a foot-sweat. Thick, yellow catarrhal discharges.

They say,

"I have had this discharge so many years," and when you investigate, you find that there has been some, shock, a cold, that suppressed the foot-sweat and it has not appeared since. Silica will bring back that sweat, cause the catarrhal discharge to cease and in time cure the foot-sweat.

Catarrhal discharges from the nose and other places, indurations, tumors, chronic gastritis, brain- fag, all dating back to the suppression of foot-sweat or otorrheoa, or to the healing up of a fistula.

Cold, clammy, offensive sweat on the forehead. When a Silica patient exerts himself he sweats on the face, the lower part of the body is dry or nearly so. It requires great exertion to produce general sweat. A striking feature is the sweat about the upper parts of the body and the head.

It is especially necessary for the Silica patient to avoid the cold air, must have the head well wrapped up, especially the part that is painful, and this part perspires copiously.

"Headache worse from mental exertion, excessive study, noise, motion, even jarring from foot-steps, light, stooping, pressing at stool, talking, cold air, touch."

Cephalatoma neonatorum, enchondroses. Silica is especially of use in the treatment of affections of the cartilages, growths about the joints, about the fingers and toes.

The complaints of Silica are associated with hardened glands, but especially about the neck, the cervical, salivary, and particularly the parotid glands; large, hard parotids. The parotids enlarge from every cold and get hard. (Bar. carb., Calc Carb Calc., Sulphur Sulph,)

Pulsatilla Puls suits the acute inflammation of the parotid, but Silica is indicated in the more chronic forms due to psora, "scrofulous glands"

Ulcers on the cornea; pustules on the lids, falling of the lashes, suppuration of the margins of the lids with burning, stinging and redness. Intense photophobia in all eye complaints.

Scrofulous cases with sore eyes, the most inveterate and chronic cases; suppuration; thin, watery, copious discharge, or bloody, thick and yellow like pus, with ulceration.

Syphilitic iritis.

"Perforating or sloughing ulcer on the cornea.

Spots and cicatrices on the cornea.

Fungus haematodes.

Affections appearing in the angles of the eyes fistula lachrymalis; stricture of lachrymal duct."

Silicea is a general survey of the eye affections in Silica

The most inveterate cases of catarrh of the ear; old offensive, thick, yellow otorrheoa; following scarlet fever; all sorts of abnormalities in hearing, even to deafness.

Roaring in the cars associated with many diseases and hardness of hearing; hissing, roaring like steam; like a train of cars, many times from mechanical cause and other times from a condition of the nerves.

It is commonly the beginning of a dry catarrh of the middle ear; the remedy is especially useful when, in catarrh of the middle ear and Eustachian tube, the deafness goes on for some time and the hearing returns with a snap, due to the escape of the accumulation of fluids somewhere and described by the patient as a snap or report.

Sudden reports in the ear like a cannon, distant noises with return of hearing.

"Otorrheoa, offensive, watery, curdy, with soreness of inner nose and crusts on upper lip, after abuse of Merc Viv Mercury, with caries."

Caries of bone in any part of the body, but especially of the small bones of the car, nose and mastoid process,

"Scabs behind the cars."

Rupture of the drum of the ear.

Catarrhal conditions of the internal car and Eustachian tube, with

"feeling of sudden stoppage in the ear, better by gaping or swallowing."

Especially with ear troubles, there will be associated indurated parotid glands.

Horrible, foetid ozaena, old syphilitic cases where the nasal bones are destroyed and the nose becomes a flabby bag, is sunken in or ulcerated away, leaving an opening. Silica may cure and an artificial nose be made afterwards.

Hep Sulph Calc Hepar competes with Silica in syphilitic nasal catarrhs where the parts are phagedenic.

Hep Sulph Calc Hepar, Mercurius Corrosivus Merc. cor. and Arsenicum Album Ars., are the principal antisyphilitics when there is phagedenic ulceration of the nose. Babies suffer from bloody nasal discharge. This is often Calc Carb Calc. Sulphur sul.

These indurations are the same kind of inferior tissue that is found under lupus and epithelioma, a low tissue formation, a low state of eczema that favors infiltration. The small blood-vessels that lead to them become thicker and thicker until they become gristly. There is a tendency to make the soft tissues harder and the hard tissues harder.

In childhood the bones become softer and even necrose or there is an inflammation of the periosteum and a consequent necrosis. Caries of the shaft of the long bones, the head of the bones and the cartilaginous portions; abscesses in cartilages, enchondromata.

The Silica patient has rough lips, they crack and peel.

rhagades. Scaly appearances at the margins of the lips, fissures in the corners of the mouth that indurate. There is often a line of fissure about the margin of the crust. Little crusts like epithelioma form upon the wings of the nose and when picked off leave a raw surface with no tendency to heal.

Crusty formations upon the ears.

The teeth break down, lose their enamel surface; the dentine is made up largely of the Calcarea Silicata silicate of lime and the surface of the tooth becomes rough, loses its shiny appearance and caries sets in.

Silicea often takes place at the margin of the gum; ulcers form on the tip of the fangs. The teeth suffer when it is cold or damp; toothache in wet weather, and the teeth are yellow, decay rapidly, and the gums settle away from. them.

All the neuralgias and toothaches are better in a warm room and from hot drinks. Abscesses about the gums and face, better by warmth. Severe pain in the jaw, rending, tearing at night, better from heat.

these pains often end in abscesses about the teeth. Sometimes relieved by pressure unless the part is extremely sore from inflammation.

The tongue takes on inflammation of gouty character; inflammation with threatening abscess, it fills the whole mouth; rending, tearing pains, worse at night and better from heat.

Quinsy with great pain in the tonsils, one or both.

threatening suppuration. Inflammation of the parotid, sublingual and much less frequently the submaxillary and cervical glands.

painful, tumid and hard, with pain in the neck, shoulders and head, even in acute inflammations. But then we have the opposite state of affairs. In an old chronic case broken down with suffering the symptoms are worse after a bath, he wants warmth, dread the cold, is always shivering.

But when in the neck there is an acute inflarnmation the very opposite is present.

he suffers from flushes of heat, an irregular, flushing fever, cold extremities while the upper part of the body is hot, sweat about the head and neck, sensation of heat and suffocation in a warm room. This will be present in quinsy and abscesses of the glands of the neck, if acute. Silica here shows its relation to Pulsatilla Puls The latter in its chronic manifestations is overburdened with heat, but in an acute trouble is chilly. They are reversed as to their acute and chronic states. Pulsatilla Puls, in the beginning is chilly and sweating.

Silica is full of throat symptoms but is seldom indicated in acute forms because its pace is too low.

it comes on after there has been a series of colds, such colds as are ameliorated a number of times by Belladonna Bell or other acute remedies but still continue to settle in the tonsils and in the glands of the neck.

Silica breaks up the tendency. There is a catarrhal state in the throat that is roused up by every cold into an increased flux, with hoarseness, settling back into the chronic state again; chronic catarrhs of the pharynx.

It competes with Nat Mur Natrum mur in inveterate sore throat.

All these symptoms are connected and are hard to separate. Decided aversion to warm food, desires cold things, wants his tea moderately cold, he is willing to have his food cold, dislikes warm food. Sometimes there is a decided aversion to meat, but if he does take it, he prefers cold, sliced meat. He likes ice cream, ice water, and feels comfortable when it is in the stomach.

it is sometimes impossible for him to drink hot fluids, they cause sweat about the face and head and cause hot flushes. (Bar. c.).

Silica is disturbed by the extremes of heat and cold, easily affected, in changes even of a few degrees; he has complaints from being overheated; he gets overheated easily, sweats easily from a slight change in the temperature and comes down with a cold.

Case A physician waiting on an obstetrical case, had a little difficulty in the last stage and he became overheated; putting on his overcoat and hat he went out on the porch to cool off and was taken down with asthma, violent cough, copious expectoration with gagging and vomiting which lasted him for months.

The acute remedies he had taken only palliated, but a dose of Silica cured him almost as quickly as he was taken down; he could not tolerate a warm room; the acute complaints of Silica are often worse in a warm room and from heat.

Silica has an aggravation from milk. Many times the infant is unable to take any kind of milk and, hence, the physician is driven to prescribe all the foods in the market if he does not know the right remedy. Natrum carb. and Silica are both useful when the mother's milk causes diarrhoea and vomiting.

The routinist is likely to give such medicines as Aethusa Cynapium Aethusa, entirely forgetting Silica The latter, as well as Natrum carb, has sour vomiting and sour curds in the stool.

"Aversion the mother's milk and vomiting."

"Diarrhea from milk."

Put these two together.

Although the patient has an aversion to hot things and desires to eat cold things, yet in chest complaints cold water, ice cream and cold, things in general, increase the cough to gagging, and then the retching is dreadful.

violent, retching, gagging cough. Retching from an endeavor to expectorate is usually controlled by Carbo Veg Carbo veg, but Silica his it.

"Water brash, with chilliness, with brown tongue; nausea and vomiting of what is drunk, worse in the morning; water tastes bad; vomits after drinking."

The Silica stomach is weak, in a do-nothing state; old dyspeptics that have been vomiting a long time, especially those who have an, aversion to hot food, who cannot take milk, are averse to meat, where, the mental and bodily symptoms agree.

Silica was one of the greatest remedies for the chronic diarrhoea in the soldiers of our Civil War. It cured a fair percentage of those sick from sleeping on damp ground, eating all sorts of food until the stomach and bowels were prostrated, from long marches, from going into the South from the cold North, from becoming overheated. It is like Sulphur Sulphur in these symptoms.

Silica has some pain in the stomach and bowels, but there is more soreness to pressure; colic and flatulence and tenderness to pressure; a chronic soreness in the stomach and if it goes on too long, a tubercular state comes on.

Enlarged abdomen in children and adults (Bar. c.); tightness across the abdomen. Disturbed by the pressure of the clothes and worse after eating; the decided feature is the amelioration from heat.

Constipation from inability of the rectum to expel the faeces. It is seldom that the stool lies in the rectum without urging like Alumina Alumina.

there is much urging to stool but inability to expel. The stool may be in small balls or large and soft or large and hard, but there is much straining and sweating about the head and great suffering while straining.

the rectum becomes impacted, he strains until he is weak and exhausted, the stool slips back.

and he gives up in despair.

The only way he can relieve himself is by some mechanical method. Great straining at stool belongs to many remedies, but especially to Alumina Alumina, Alumen Alumen, China China, Nat Mur Natr. mur., Nux Vomica Nux vom., Nux Moschata Nux mosch., and Silica.

Silica has removed tape-worm, when the symptoms agree(Calc Carb Calc., Sulphur Sulf)

It has also cured fistulous openings. Patients who have a tendency to phthisis are subject to abscesses about the region of the rectum, that break inside or out and form complete or incomplete openings.

These seem to take the place of what would otherwise come, and if healed by operation or other external means, the tendency is to end in chest trouble, either in form of a fixed catarrh or tubercular infiltrations.

Silica is one of the remedies that turns the constitution into order and in one to five years the opening ceases to be necessary and it will heal. Surgeons heal it up at once, and for a time the patient is comfortable, but in a few years he breaks down.

Causticum Caust., Berberis Vulgaris Berb., Calc Carb Calc. c., Calc Carb Calc. Phosphorus phos., Graphites Graph., Sulphur Sulph, etc., are suitable; in such cases. Silica here follows Thuja Thuja well.

Urinary Suppurative conditions in the urinary tract, catarrh of the mucous membranes; old inveterate catarrh of the bladder with pus and blood in the urine; copious, stringy, deposits in the urine.

Men Abscesses along the penis, in the perineum, prostate gland, testes.

Chronic inflammation and induration of the testes with much pain; testes feel as if squeezed, sensitive, painful. Hydrocele in boys or adults.

In the male, impotence, weakness of the genitals after coition, easily exhausted, lacks power; exhausted if he has coition with anything like ordinary frequency; it takes him a week or ten days to rest up (Agaricus Muscarius Agar).

Much sweating of the genitals with exhaustion, tired out in the spine, weak back. Involuntary discharge of urine at night; enuresis in little boys and girls.

Women In women a prostrated condition of the sexual functions.

Serous cysts in the vagina, fistulous openings and abscesses about the vulva, which heal with hard nodules or do not heal at all; little oozing fistulae, offensive, cheesy discharge. They heal in little nodules and then break out again in the same nidus. Women who are subject to these abscesses.

Bloody discharge between the periods. In Silica there is very easy flow of blood from the uterus; a hemorrhagic flow comes on before the menses from excitement, and especially when nursing; when the child is put to the breast a flow of blood starts.

Notice the distinction between Calc Carb Calc and Silica. Calc Carb Calc. has a tendency to flow during lactation, but not when the child is put to the breast.

Silica cures hydrosalpinx and pyosalpinx, with copious, watery discharge from the uterus. Sometimes a woman has a lump on one or the other side of the uterus, which steadily increases and all at once there is a flooding of watery, bloody, purulent fluid and the lump disappears, soon to fill up again and empty in the same way in a gushing flow.

Such are the manifestations of hydrosalpinx and pyosalpinx. Entire absence of the menses for months; amenorrhoea.

Serous, cysts in the vagina as large as a pea or an orange, projecting from the vagina or projecting upwards and flattened out in conformation with it. Many little cysts like hickory-nuts grouped together. Rhododendron Rhod and Silica have cured these even when there is a paucity of other symptoms.

Threatened abscesses of the breasts. If the remedy is given in time, it will abort the entire trouble. Where the remedy has come too late and suppuration is inevitable, Silica comes in for its share. There may be throbbing, tenderness, and weight, yet the remedy controls the pain, hastens the conclusion, and the opening comes naturally, discharges little and closes at once. As sure as an anodyne is given, a hot poultice applied, you will fail with your remedies.

There is too much blood in the part, and the application of a poultice increases the trouble; it causes an increased determination of blood to the part, and if suppuration takes place it causes more breaking down of tissue. Instead of a thimbleful of pus you will have cupfuls for days and half of the gland is destroyed

Women who are so weak they tend to abort, or no conception takes place. It would seem if the organs were tired out and unable to perform their functions.

The infant has all sorts of troubles. It grows up sickly; cannot tolerate its mother's milk or indeed any kind of food; vomiting and diarrhoea. A healthy child will digest even unwholesome milk.

If there is small abscess in the lung with no tendency to heal, it brings about repair, causes contraction of its walls. Inveterate cases of catarrh of the chest with asthmatic wheezing, overexertion. After violent exertion and overheating, gets in a draft, or takes cold from a bath, becomes chilled.

Humid asthma, coarse rattling, the chest seems filled with mucus, seems as if he would suffocate. Especially the asthma of old sycotics, or in children of sycotic parents. It competes with Nat. sul in such cases. The patient is pale, waxy, anaemic, with great prostration and thirst.

Asthmatic attacks from suppressed gonorrhoea, with liability to develop complaints from over-exertion and over-heating, as in most sycotics.

Dry, teasing cough with hoarseness, threatening tuberculosis of the larynx, peculiar cracked voice from thickening of the laryngeal mucous membrane or tubercular involvement; soreness of the chest threatening miliary tuberculosis, with aggravation from cold and amelioration from warm drinks.

Pulmonary affections in stone-cutters. The fine dust causes chronic irritation. Silica establishes a suppuration and throws off these particles of stone.

Chronic tendency for colds to settle in the chest and bring on asthmatic symptoms. Chronic bronchitis; inflammation of the lungs with suppuration. Silica especially suits the later stages of pneumonia and the old, chronic complaints following pneumonia.

Slow recovery after pneumonia (Lycopodium Lyc., Sulphur Sulph., Phosphorus Phos., Sil., Calc Carb Calc.). Flushes, rattling in the chest. Flushes in the face during the day (Sulphur Sulph., Sepia Sep., Lachesis Lach), rattling like Antimonium Tartaricum Ant. tart., flushes like Sulphur Sulph and Lycopodium Lyc

Phthisis; thick, yellow, green, foetid sputa, more pronounced coldness than Calc Carb Calc, and head sweat, pains in the lungs, sore lungs, stitches.

In the extremities we have inflammation of the periosteum. Corns (Antimonium Crudum Ant. cr., Graphites Graph). Ingrowing toe-nails. Rheumatism of the soles of the feet. Cannot walk (Antimonium Crudum Ant. cr., Med., Ruta Graveolens Ruta, Sil). Begins to sweat as soon as he falls asleep (Pulsatilla Puls., Conium Mac Con).

Epilepsy; aura in the solar plexus creeping into the chest and stomach.

ache worse from cold air. Psorinum Psor wears a fur cap even in summer. Manganum Muriaticum Mg. mur is better from wrapping up the head but still wants to be in the air. Rhus Tox Rhus sweats on the body.

the head is dry. Pulsatilla Puls sweats on one side of the head.

The aspect of the Silica face is silky, anemic, waxy, tired. Pustular and vesicular eruptions spread over the face, the wings of the nose crack, the lips easily fissure.

crusts form on the margin between the mucous membrane and the skin.

eruptions and crusts, indurations form under the crusts, they peel off and there is no healing.

Weak, puny children; not from want of nourishment taken, but defective assimilation.

Inflammations tending to end suppuration or refusing to heal; becoming chronic.

Coldness, lack of vital warmth, even when taking exercise; must be wrapped up, especially the head, which better.

Suppressed sweat, especially of feet, which is profuse and offensive.

Weak, nervous, easily irritated, faint-hearted; yielding, giving up disposition, "grit all gone." Constipation; stool protrudes and then slips back again, again and again; week expulsive power.

Modalities worse from cold or draft, motion, open air, at new moon; better in warm room, wrapping up head; magnetism and electricity.

Scrofulous, rachitic children with large heads; open fontanelles and sutures; much sweating about the head, which must be kept warm by external covering; large bellies; weak ankles, slow in learning to walk.

Diseases, caused by suppressed foot sweat; exposing the head or back to any slight draft of air; from vaccination (Thuja Thuja); dust complaints of stone cutters, with total loss of strength.

Vertigo; spinal headache ascending from nape of neck to head, as if one would fall forward; worse looking upward.

Unhealthy skin; every little injury suppurates.

Promotes expulsion of foreign bodies from the tissues, fish bones, needles, bone splinters.

Silicea is another of our invaluable constitutional remedies, and also one which is of little or no use except as developed by Hahnemann's process of potentization. Like Calc Carb Calcarea, it is especially useful in sweaty-headed children (Sanicula) with defective assimilation. It is not in the fat, torpid, obesic patients, over-nourished in one part and insufficiently so in another, like Calc Carb Calcarea that Silicea is indicated, but in the over-sensitive, imperfectly nourished (generally), not from want of food, but from imperfect assimilation. The Silicea child is not larger than natural anywhere except in its "big belly," which is due to diseased mesentery. Silicea's limbs are shrunken, its eyes sunken and its face pinched and old looking. It does not increase in size or strength, learns to walk late; in short, if not actually sick in bed, everything seems to have come to a standstill so far as growth or development is concerned. Now if this state of things continues the bowels become very constipated, and a peculiar constipation it is, too. The little fellow strains and strains, the stool partly protruding and then slipping back (Sanicula and Thuja Thuja), as though the general weakness of the patient affected the expulsive power of the rectum, or else the bowels become very persistently loose, especially during dentition or the hot weather of summer. The stools are changeable, but Pulsatilla Pulsatilla does no good, almost every kind and color of loose stool appearing. The child takes nourishment enough, but, whether vomited or retained, goes on emaciating and growing weaker and weaker until it dies of inanition, unless Silicea checks this process. Many such cases have I saved with Silicea and made them healthy children. I have always used the 30th and upwards, hence cannot speak of the lower preparations. (Silicea also has constipation worse before and during menstruation).

Silicea ranks among the first of our remedies for inflammations ending in suppuration. It seems to make no particular difference whether the suppuration takes place in the soft or hard parts, for it is equally efficacious in glandular or bony ulcerations. It seems to come in at a later stage than Hep Sulph Calc Hepar sulph. or Calc Carb Calcarea sulphide which expedite the discharge of pus already formed, while Silicea comes in for healing after the discharge has taken place. Cellular tissues with deep-seated suppurations, including tendons and ligaments, also come within the range of its healing powers. In these cases the constitution of the patient has an important bearing in the selection of Silicea. The Silicea subject is weakly, with fine skin, pale face, lax muscles. Even the mind and nervous symptoms come into the general picture of "weakness." He is nervous and irritable, weak, faint-hearted, yielding, giving-up disposition, "grit all gone." (Pulsatilla Pulsatilla). In such a case Silicea is grand. I hate to use the term, but as the old school would say, "it builds them up," and so it seems, for under its action the patients spirits rise, hope revives, the weakness and depression give way to a feeling of returning strength and health. It makes no difference whether the ulcerations are in the tissues already named, in the lungs, intestinal tract, or mammae, or elsewhere, the effect is the same, and the improvement in the local affection generally follows the general constitutional improvement. This condition of weakness seems to attack the general nervous system, affecting the spine, and so we get those cerebro-spinal headaches, or headaches beginning in the nape of the neck and running forward over the head to the eyes, for which Silicea is so useful. Vertigo also ascends from the nape to head, worse looking up. (Pulsatilla Pulsatilla).

There seems to be lack of nerve power to resist outward depressing influences. He is cold, or, as Hering puts it, there is "want of vital warmth, even when taking exercise." He is sensitive to cold air, takes cold very easily, especially when uncovering the head or feet. On the contrary, he is relieved by "wrapping up the head" (Magnesia Muriatica Magnesia mur.), or, in other words, supplying artificially the warmth that he lacks naturally.

I have several times found a Silicea child suffering from epileptiform spasms which were always worse at new moon. A few doses of Silicea 200th set them all right.

Silicea subjects are often afflicted with offensive foot-sweats (Sanicula, Psorinum Psorinum, Graphites Graphites), which are easily suppressed by getting the feet cold. Such suppression must be remedied, the sweat restored and cured by proper medication or serious results often follow, such as convulsions and other spinal troubles, even locomotor ataxia. Silicea is the remedy to restore and cure such sweats by correcting the conditions upon which the sweats depend. (Baryta Carb Baryta carb., Graphites Graphites, Psorinum Psorinum, Sanicula).

The Silicea patient desires to be magnetized and is relieved thereby (Phosphorus Phosphorus).

Silicea is one of the remedies of which, like Sepia Sepia, Lachesis Lachesis, Lycopodium Lycopodium and others, the old school knows little or nothing, because their chief virtues are only developed in potencies above the 12th.

Silicea is the chronic of Pulsatilla Pulsatilla.


Sixth to thirtieth potency. The 200th and higher of unquestioned activity. In malignant affections, the lowest potencies needed at times.

Outside homoeopathy Flint as an internal remedy is practically unknown. Hahnemann introduced it into medicine, and it was his method of attenuating insoluble substances that enabled him to discover its powers. Silica forms one of the most important remedies of the Chronic Diseases. A large proportion of the earth's crust is composed of Silica. Sea sand (Silica marina) is mainly composed of it. The spicules of many sponges are made up of Silica. Silicates are taken up by plants and from them Silica is often deposited on the surface or in the interior of their stems. The strength of straw is due to Silica. Equisetum Hyemale Equisetum generally contains as much as 18 per cent. of Silica to the fresh plant. Flint supplies the "grit" of the earth's crust, of plant life, and to a large extent of animal life also. "Want of grit, moral or physical," is a leading indication for Sil. in homoeopathic practice. Teste puts Sil. in his Pulsatilla Pulsatilla group of remedies, the other members of it being Calc Carb Calc., Hep Sulph Calc Hep., Graphites Graph., Phosphorus Pho. According to Teste, Sil. is the "chronic" of Pulsatilla Puls.,

If a suppurative centre is formed either in the connective tissue or in a portion of the skin, Sil. may be used.

After the functional ability of the cells of the connective tissue, which had been impaired by the pressure of the pus, has been restored to its integrity through a supply of molecules of Sil., these cells are thereby enabled to throw off inimical substances (the pus). In consequence, the pus is either absorbed by the lymphatics or it is cast out. In the latter case there is a so-called spontaneous breaking open of the suppurative centre.

Sil. will also cure chronic arthritic-rheumatic affections, as it forms a soluble combination (Sodium silicate) with the soda of the urate of soda; this combination is then absorbed and removed through the lymphatics. For the same reason it may also be used in renal gravel.

Sil. can also restore the perspiration of the feet when this has been suppressed, and is thus an indirect remedy in diseases arising in consequence of such suppression (e.g., amblyopia, cataract, paralysis, &c.).
