A blister to the nape of the neck, leeches to the temples, and nauseating doses of tartar emetic with saline purgatives have rapidly dispelled the symptoms in all the cases I have met with, and have restored the patient to perfect health. _Conclusion._ The preceding cases constitute an abstract of my experience on this subject, and constitute the grounds of my belief that in hemp the profession has gained an anti-convulsive remedy of the greatest value. Entertaining this conviction, be it true or false, I deem it my duty to publish it without any avoidable delay, in order that the most extensive and the speediest trial may be given to the proposed remedy. I repeat what I have already stated in a previous paper--that were mere reputation my object, I would let years pass by, and hundreds of cases accumulate before publication; and in publishing I would enter into every kind of elaborate detail. But the object I have proposed to myself in these inquiries is of a very different kind. To gather together a few strong facts, to ascertain the limits which cannot be passed without danger, and then pointing out these to the profession, to leave them to prosecute and decide on the subject of discussion, such seems to me the fittest mode of attempting to explore the medicinal resources which an untried remedy may afford. It may be useful to add a formula for making the preparations which I have employed. The _resinous extract_ is prepared by boiling the rich, adhesive tops of the dried _gunjah_, in spirit (sp. gr. 835), until all the resin is dissolved. The tincture thus obtained is evaporated to dryness by distillation, or in a vessel placed over a pot of boiling water. The extract softens at a gentle heat, and can be made into pills without any addition. The _tincture_ is prepared by dissolving the extract in spirit of 835° density. _Doses, &c._--In _tetanus_ a drachm of the tincture every half hour until the paroxysms cease, or catalepsy or narcotism is induced. In _hydrophobia_ I recommend the resin in soft pills, to the extent of ten to twenty grains to be chewed by the patient, and repeated according to the effect. In _cholera_, thirty drops of the tincture every half hour will be often found to check the vomiting and purging, and bring back warmth to the surface. My experience would here lead me to prefer _small_ doses of the remedy in order to excite rather than narcotise the patient.
