There is another mode of practice which has been exhibited to some extent in almost every part of the world, claiming to be more efficacious and successful than any other in the cure of epidemic cholera. It is the general principle which is the great and important consideration with which we are concerned in presenting it among the various modes adopted for the cure of this disease. This is found clearly defined and ably presented by Dr. Joslin in his lecture on cholera, in which, after exhibiting the views and doctrines governing the practice, and contrasting its results with those of other modes, he observes, in relation to the treatment of cholera in its early stages, that "whatever may be the form of attack, give one drop of the tincture of camphor dropped on a lump of sugar, and then dissolved in a table-spoonful of cold water. Repeat this every five minutes until there is a decided mitigation of the symptoms. This will usually be after five or six doses. If the disease be taken in time, ten or twelve doses are ordinarily sufficient. There is abundant testimony of the efficacy of this camphor treatment from all parts of Europe." Again, speaking of the first variety, in which the most prominent symptom is diarrhoea, the Dr. observes, "If camphor does not soon give relief, we are to resort to phosphorus, or to phosphoric acid. Dr. Quinn has employed both with equal success. Phosphoric acid is to be preferred when there is a gluey matter on the tongue. In some cases, veratrum, chamomilla, mercurius, or secale may be indicated. However, phosphorus and phosphoric acid rarely fail to cure; and some high authorities are in favor of giving one of them at first, in preference to the administration of camphor in this form of cholera." Again, in the second variety, cholera gastrica, Dr. Joslin observes, that "the remedies are generally ipecacuanha or veratrum, sometimes nux vomica. Camphor is to be given at the outset. Put two or three globules of the third of ipecac. in a little sugar of milk and place them on the tongue. This may be repeated, if necessary, in half an hour, an hour, or an hour and a half. But if the disease is not checked, give veratrum or other medicines according to the different indications." Again, in the third variety, cholera spasmodica, "the remedies are camphor, cuprum metallicum, and veratrum. If camphor has not relieved, give cuprum, and repeat it many times, at intervals of half an hour or an hour, if its salutary effect is not manifested. If necessary, then give veratrum in repeated doses, or other medicines, according to the different indications." In the fourth variety, cholera sicca, "there is no diarrhoea or vomiting; there is sudden prostration of the vital powers," etc. "The first remedy, as in other varieties, is camphor. If the patient is cold, blue, pulseless, that is, collapsed, carbo vegetabilis; some recommend hydrocyanic acid." In the fifth variety, cholera acuta, veratrum is named as the main remedy.
