VETEEINARY MEDICDTE. 



A new treatise on general pathology, compiled by C. Bouchard and G. H. 

 Roger (Novveau Traits de Patlwlogie 0&n4rale. Paris, 1912, vol. 1, pp. X/7+ 

 909, figs. 53). — This is tbe first edition of tliis worli, and is edited by C. Acliard, 

 J. Bergenia, P. J. Cadiot, P. Courmont, M. Duval, P. Mulon, A. Imbert, J. P. 

 Langlois, P. Le Gendre, F. Lejars, P. Le Noir, T. Nogier, H. Roger, and P. Vuil- 

 lemin. It is wholly distinct from the pathology published by Bouchard and 

 Roger from 1895-1905, and is arranged on an entirely diiJierent plan. 



Results of research in the general pathology and pathologic anatomy of 

 man and animals, edited by O. Lubaesch and R. Ostertag {Ergeh. Allg. Path. 

 Meiisch. u. Tiere, 15 {1911), pt. 1, pp. IX+823, figs. 61).— The contents of this 

 volume are as follows : The Proteolytic Leucocyte Ferment and its Antifer- 

 ment, by P. Wiens (pp. 1-81) ; Loss and Changes In the Functions of the Thy- 

 roid Gland as a Cause of Disease, by B. Bircher (pp. 82-377) ; Hermaphro- 

 ditism Considered from a Moriohologlcal Standpoint, by E. Sauerbeck (pp. 

 378-429) ; About Embryonal Tissue Anomalies and their Pathologic Significance 

 in General, Especially Those of the Male Sexual Apparatus, by R. Meyer (pp. 

 430-649) ; Double Formations in Man and Animals, by H. Hiibner (pp. 650- 

 796). A large bibliography is api^ended in each case. 



Physical theory of immunity and its experimental basis, O. Gengou 

 {Jour. State .Med., 20 {1912), Nos. 2, pp. 65-91; S, pp. 141-112).— The author 

 believes that although the physical theoiy of immunity formulated by Bordet 

 in 1899 does not yet give an absolutely precise explanation, demonstrated be- 

 yond doubt, bf all the characteristics of the reactions which take place between 

 the antigens and the antibodies, " it is none the less true that, founded from 

 the beginning on experimental facts such as the phenomenon of Bordet and 

 Danysz, it is still the only one up to this day which has furnished from these 

 facts a satisfactory explanation, whereas the theories which have been pro- 

 pounded from their consequence have not been able to withstand criticism or 

 experimental verification. 



"As the knowledge of the phenomena of absorption becomes more precise 

 and the mechanism of humoral reactions has been more thoroughly investi- 

 gated, the number of facts which can be reconciled with Bordet's theory has 

 grown increasingly, while no phenomenon has shown itself to be formally con- 

 tradictory to it, and its experimental bases have been progressively fortified 

 and developed. Whether it is a question of the quantitative relations in which 

 the antibodies unite with the antigens, or of factors which are opposed to this 

 union, whether it is a further question of the reversibility or the consolidation 

 of this phenomenon, Bordet's theory shows itself to be in harmony with the 

 facts and without restraint and new hypothesis. It is to be hoped that such 

 will be the case, that each experimentalist investigating the mechanism of the 

 phenomena of immunity can put to the best advantage his researches on the 

 advances realized in the study of molecular adhesion and the reactions In 

 which colloidal substances take part." 



The antigenic properties of split products of casein, F. P. Gay and T. B. 

 Robertson {Jour. Expt. Med., 16 {1912), No. Jf, pp. JtlO-.'il8). — Chemically pure 

 casein and some of its split products were examined in regard to their antigenic 

 properties. 



"Casein and paranuclein have distinct antigenic properties, particularly as 

 shown by their ability to sensitize guinea pigs for subsequent anaphylactic
