The original of this book is the authoritative work on veterinary medicine in Germany. Its French translation has been made a text-book on this subject in French veterinary schools. This volume in particular will interest physicians because it deals with the infectious diseases of animals. Owing to the undesirable limitation often placed on the term pathology, especially in this country, in which it is frequently employed as synonymous with pathologic anatomy, it is necessary to state that this work deals fully with the clinical aspects of veterinary diseases, that it is in fact a work on veterinary medicine. The translation is a welcome addition to English literature because it places within easy reach comprehensive and authoritative information concerning diseases of domestic and other animals, a subject of increasing interest and importance to human medicine.
