In order to render the work as valuable as possible to the general practitioner, its scope has been made as comprehensive as could be done without exceeding the limits prescribed by the nature of the undertaking. This will be particularly noted in the section on Gynæcology, where is presented a series of articles by eminent specialists upon the subjects of chief importance to the general practitioner, written with special reference to their constitutional relations and their bearings on associated morbid conditions, while, among the general diseases, a full article on puerperal fever has properly been included. Important articles will also be found on Tracheotomy, the Diseases of the Rectum and the Anus, and those of the Bladder and the male sexual organs. Comprehensive sections have further been provided, from the pens of distinguished specialists, upon medical ophthalmology, medical otology, and on skin diseases, presenting these large and complicated subjects in a clear and practical light and with special reference to their relations to general medical practice. In the presentation of such subjects as hydrophobia, glanders, and anthrax care has been taken to ensure the full discussion of these affections, not only as occurring in man, but also in the lower animals, since it is highly important to provide the physician with authoritative information on at least such points of Veterinary Science as have a direct practical bearing on morbid processes in man. In view of the intimate relations of all questions of hygiene to the causation and prevention of disease, in regard to which medical men are constantly consulted, and are, indeed, often obliged to assume weighty responsibilities, interesting articles on Drainage and Hygiene have been provided.
