The Brunswick chicken plague, Jess ( C'cn^W. Bait. u. Par., 1. Aht., S9 {1901), 

 No. 19, pp. 755-757). — A disease whicli bore certain resemblances to fowl cholera, 

 roup, and arsenic poisoning, was investigated by the author. It was found that affected 

 birds exhibit the first symptoms of disease about 3 days after exposure to infec- 

 tion. As a rule death occurred about 7 days after the beginning of the disease. 

 A microscopic study of diseased fowls showed the presence of several pathogenic 

 organisms, one of which appeared to l)e that of fowl cholera, while the others were 

 distinct and were found in greatest alaindance in disea^ied patches which occurred in 

 the throat. The author believes that the disease is therefore due to a mixed infec- 

 tion. Attention is called to the necessity of exercising care in disinfecting poultry 

 yards and l>uildings in order to prevent the spread of the disease. 



The diseases of the cat, J. W. Hill {Neiv York: William R. Jenkins, 1901, pp. 

 123, pis. 10). — In this vohmie the author has brought together a discussion of the 

 symptoms, causes, and i-emedies for all of the diseases which commonly affect 

 domesticated cats. Special chapters are devoted to diseases of the respiratory 

 organs, diseases of the stomach, of the intestines, of the skin, of the ear, of the eye, 

 mammary glands, and nervou"9 system. Tlie problems connected with abandoned 

 cats, with the feeding and washing of cats in health, and the destruction or disinfec- 

 tion of diseased cats are also discussed. One chapter is devoted to general diseases, 

 infectious or otherwise; and accidents, together with their treatment, as well as 

 poisons and the proper antidotes also receive due consideration. 



A method for simple determination of the value of chemical disinfectants, 

 T. Paul {Entvurf zur einheitlichen Wertsbestimmuug clicmiscJier Desinfek(ion.smiileL Ber- 

 lin: Julius Springer, 1901, pp. 54, figs. 8). — Especial attention is called to the desira- 

 bility of simple methods for rapid determination of the real value of disinfectants 

 which are proposed for jjractical u.se in the destruction of pathogenic organisms in 

 houses and stables, after the occurrence of infectious diseases. As a rule the meth- 

 ods proposed for such determination are considered defective, or as based upon 

 inconclusive experiments. It is urged that experiments along this line should be 

 conducted in a more uniform manner and with all factors under better control, in 

 order that reliable results may be obtained. The virulence of the organisms to be 

 used in the experiments must be carefully determined and care must also be exer- 

 cised in an accurate determination of the solution in Mhich the organisms are placed, 

 and the strength of the solution of the disinfectant. 



Studies on bacillol, F. P.\szott.\ {Immg. Diss., Univ. Bern, 1901, pp. 35). — From 

 the numerous experiments conducted by tJ)e author, it was concluded that bacillol is 

 soluble in water under all circumstances, and forms constant solutions. When 

 bacillol is applied, in concentrated form, to the skin it is slightly caustic like lysol. 

 It is considered a powerful antiseptic and deodorizer. It is to be obtained more 

 cheaply than most other similar drugs. It should be administered in the same way 

 as lysol or creolin. When given internally it causes a slight increase in salivation 

 and an increased cardiac and respiratory action. In large doses it may cause motor 

 paralysis or trembling. It is rapidly excreted hy means of the kidneys. 



Zoological materia medica. History of drugs ot animal origin, H. Beacre- 

 CiMAU {Maliere medtcale zoologtqne. Htsloirt dts drogues (rorigme animale. Paris: C. 

 Navd, 1901, pp. 396, figs:. 145).— The general anatomical characters of mammals are 

 discussed, with special leleience to the stmctures whicli are concerned in the pro- 

 duction of substances used lor medical purposes. In connection with the considera- 

 tion of various species of mammals, reptiles, fishes, crustaceans, insects, worms, and 

 sponges, the anatomical and chemical character ot the various drugs which are 

 obtained from each species are mentioned and critically discussed. The work con- 

 tains a valuable and (onvenient summary ot ttie present state of knowledge concern- 

 ing various drugs of animal origin.
