The same comfortable tranquillizing effect, and at the end of an hour a little sleepiness, which soon passed off,

A pleasant quieting effect, hardly amounting to sleepiness,

The sleep is calm and interrupted by the least noise.

but one goes to sleep again immediately.

on awaking there is freedom from the heaviness of the head experienced after the use of Morphia, and there is less liability to vomiting and constipation.

A slight narcotic effect,

Of all the alkaloids contained in Opium, Narcein possesses hypnotic power to the greatest extent; in the great majority of cases, neither Morphia nor Codeia produced so long or so profound a sleep,

When given internally or externally for pain, it often produces a sleep of four, five, or even nine hours, a sleep which is soft, tranquil, uninterrupted, and followed by a quiet waking,

Narcein causes, only in a very feeble degree, the physiological phenomena consequent upon the sleep produced by Morphia and the salts of that base,
