The book has been used as a guide in the treatment of cho lera, not only by the profession, but by many intelligent lay men. In this rapid disease, for which our system affords the only effectual remedies, many families in localities where no homoeopathic physician can be soon procured, Will find it ne cessary at last to commence the treatment; and some mem bers Of the profession who had been previously allopathic will be induced to prescribe homoeopathically for cholera. In consideration of the wants of these two classes, the more im portant rules of treatment are given in a more particular and elementary form, than would be necessary for an experienced homoeopathic practitioner. The plain rules for prevention, preliminary treatment and nursing, may either be consulted directly by families, or employed by their physician as a safe and convenient basis for his instructions.
