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.

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.).
