The call for second edition of this book a short time after appearance of the first, is worth apperception for W A Dewey. It is designed as a companion to the "Essential of Homeopathic Materia Medici", and has created for itself, the required space. Although named therapeutics, it is materia medica arranged in question answer form. The book has been thoroughly revised and numerous errors, which appeared in first edition have been rectified and many characteristic indications added.
