n:ompendium der Speziellen Pathologie und Therapie fUr Tierarzte. Pub-lished by Ferdinand Enke, Stuttgart, 1932. Price 23 Marks.

In the new edition of this well-known book the organ diseases are dealt with by Prof. Frohner as in previous editions, while Prof. Zwick is responsible for the contagious diseases.

It is mainly designed for students, and the authors have exercised sound judgment in deciding what it is reasonable to include in such a work. In general, the amount of space devoted to each subject corresponds with the importance of the disease. The text is concise, clear, and up-to-date.

Filterable Virus Diseases in Man. By Joseph Fine, M.D., B.SC. Edinburgh: E. and S. Livingstone, 1932. Price 6s. net.

This small book (134 pages) has been designed in order to make accessible to senior medical students and interested medical practitioners up-to-date information regarding the extensive and important group of human diseases caused by what are usually called the ultra-visible viruses. It can be strongly recommended for that purpose.

For the purpose of description the author has grouped the filterable virus diseases according to their method of transmission. Divided in this way, they form six groups: (1) The yellow fever group; (2) the typhus group; (3) the dermotrophic group (affecting skin or mucous membrane) ; (4) the neuro-dermotropic group (affecting the nervous system and skin); (5) the neurotropic group (affecting the nervous system only); (6) the respiratory group.

In separate chapters the different viruses are described with regard to recent history, effect of physical and chemical conditions, filterability, pathogenicity for animals, vector, and immunology.

The author has made an exception to the rule that he would only include the essentially human diseases, for rabies is dealt with.

At the conclusion of each chapter there is a useful bibliography.

Die Streptokokkeninfektionen des Euters. By Dr. M. Seelemann. Published by M. and H. Schaper, Hannover, 1932. Price 14 Marks. Pages 259.

Dr. Seelemann is one of the best known of the earnest band of workers who have set themselves to study the retiology and biology of the inflamma­tory diseases of the cow's udder, and he has done well to give, in this monograph, the fruit of his investigations up to the present time. The work can be most strongly recommended to both medical men and veterinary surgeons, as it is packed with information of the greatest interest.

It has gradually been recognised that, although there are different kinds of mastitis in the cow-that is, inflammations caused by different micro­organisms-the prevalent type is the one of which the description can be traced back in literature in Switzerland and Germany under the name of " gelbe Galt," and for which streptococci are responsible.

The information is arranged in separate chapters which deal with the history of the disease, its scientific importance, its causes, the methods of infection, the technique of milk examination, the organisms concerned in the
