ing veterinary courses. The classification of tlie lectures is as follows: Introductory, 

 including various anatomical and physiological data; bones; muscles; hoofs and 

 shoeing; digestive organs; dentition; circulatory and lymj)hatic systems; respiratory 

 organs; nervous diseases, including those of the special senses; skin diseases; and 

 urinary diseases. The number of specific diseases of various sorts which are men- 

 tioned in the volume is sufficient to include all the more important ones. In the 

 appendixes valuable information is furnished in a brief form regarding the nature of 

 various diseases and treatment to be given; the nature of various medicines; formulas 

 for preparing veterinary medicines, and a tabulated list of medicines with the usual 

 size of doses for horse, sheep, pig, and dog. 



Treatise on surgical therapeutics of domestic animals, P. J. Cadiot and J. 

 Almy ( Traite de therapeutique chirurgicale des anbncmx dome»tiques. Paris: Asselin ifr 

 Houzeau, 1903, vol. 2, -2. ed., x>p- 744, figs. 310). — In this volume the authors present 

 a detailed and critical discussion of diseases of the withers, back, loins, chest, abdo- 

 men, tail, legs, and feet. The diseases of the abdomen are classified according to 

 the organ or parts affected. The pathological conditions and surgical instruments 

 used in the treatment of these affections are well illustrated. 



The formation of precipitates during agglutination, M. Lowit {CentM. Bakt. 

 u. Far., 1. Aid., 84 {1903), Nos. 2, Orlg., pp. 156-166; 3, Orig., pp. 251-259, pi. 1).— 

 The author attacked the problem of determining the nature of agglutination in bac- 

 terial cultures. It was found that a homogeneous connecting substance in varying 

 quantities was always to be demonstrated in cases of agglutination. This connecting 

 substance exhibited a considerable affinity for eosin and certain other stains, and 

 could therefore be demonstrated with considerable ease. The author believes, there- 

 fore, that he has furnished morphological proof of the fact that the agglutination of 

 bacteria is to be considered as essentially a process of precipitation. The author con- 

 cludes that in cases of agglutination precipitates are formed in and upon the bacteria 

 concerned and perhaps also in the surrounding fluid. The substance necessary for 

 the formation of the precipitate is believed to come from the bacterial cells. 



On the protective substances of immune sera, E. W. A. Walker {Jour. Ilyg. 

 [Cambridge], 2 {1902), No. 1, pp. 85-100). — The experiments reported in this paper 

 were made with typhoid bacillus upon guinea pigs. The following results were 

 obtained: The quantity of immune body required for protection against a given 

 number of minimum lethal doses of the bacterial organism is in general an equal 

 number of cubic centimeters of the immune serum. The complement is a leucocytic 

 ferment not strictly specific. It is increased by the process of immunization. 



The relationship between toxin and antitoxin, P. Eisenberg ( Centbl. Bakt. u. 

 Par., 1. Abt., 34 {1903), No. 3, Orig., pp. 259-283).— The literature of this subject is 

 critically reviewed in connection with a bibliography. The author found during his 

 investigations that the relative amount of toxin required for the neutralization of the 

 antitoxin varied according to the total amount of the mixture. Where large quanti- 

 ties of each were used a relatively larger amount of toxin was required for the neu- 

 tralization of the antitoxin. 



Further contributions to the theory of bacteriolytic immunity, R. Pfeiffer 

 and E. Friedberger {Centbl. Bakt. u. Par., 34 {1903), No. 1, Orig., pp. 70-84).— The 

 authors' experiments as reported in this article were concerned chiefly with the 

 formation of immune bodies antagonistic to bacteriological amboceptors, with special 

 reference to the vibrio of cholera. During these experiments it was found that in the 

 serum of an animal treated with the immune serum of cholera, antiamboceptors arise 

 which attack the cytophilous group of the amboceptors. The antiamboceptors pos- 

 sess no affinity for the receptors of the cholera vibrio. Antiamboceptors are rela- 

 tively stable bodies which are not destroyed by subjection to 60° C. for ^ hour. 



Experimental studies on disinfection by means of formaldehyde and steam, 

 H. Herzog ( Centbl. Bakt. u. Par., 1. Abt., 34 {1903), No. 2, Orig., pp. 170-187, figs. 2).—
