VETERINARY SCIENCE AND PRACTICE. 603 



In these experiments it was found that the flagellar and somatic agglutinins and 

 other agglutinable substances of the hog-cholera bacillus may be successfully differ- 

 entiated by the application of heat. The somatic agglutinin of the serum and the 

 flagellar agglutinable substance of the hog-cholera bacillus are considerably influence 1 

 by exposure to a temperature of 70° C. for a period of 20 minutes. 



A somewhat higher temperature is required in differentiating the flagellar and 

 somatic bodies of the hog-cholera bacillus than is necessary for separating the same 

 bodies in the typhoid bacillus. While a temperature of 70° 0. is sufficient to destroy 

 the agglutinating power of motile hog-cholera bacilli, this degree of heat does not 

 affect their power of producing flagellar agglutinins in the animal body. 



General pathology of domesticated animals, C. Cadeac (Pathologie giniral des 

 animaux domestiques. Paris: J. />. Baill&n & Sons, 1904, 2.ed., pp. X-\- ./•/.', figs. 37). — 

 In this volume, which constitutes the first of a series under the title of veterinary 

 encyclopedia, various matters concerned with the general pathology of animals are 

 discussed. 



The subjects treated in the volume include the definition of disease in general; the 

 influence of heredity, age, constitution, and other properties of the organism upon 

 the course of the disease, and also the influence of environment, animal parasites, and 

 bacteria upon the production of disease. A general discussion is also presented of 

 symptomatology and functional disturbances. 



Report of the veterinary department of the Minnesota State Board of 

 Health, 1903, S. D. Brimhall, F. F. Wesbrook, and H. M. Bracken (St. Paul: 

 Pioneer Press Co., 1903, pp. 404, pis. 15). — This report covers the veterinary work of 

 the Minnesota State Board of Health from August 1, 1900, to May 1, 1903. During 

 this period detailed experimental studies and observations were made on a consider- 

 able variety of animal diseases. Copies are given of recent laws in Minnesota regard- 

 ing the control of animal diseases. 



Bovine tuberculosis was studied in some detail (pp. 26-54). As a result of the 

 extensive application of tuberculin tests to dairies it is suggested that compulsory 

 testing of dairy herds would be continued only on condition that some means be 

 provided by which dairymen may replenish their herds with tested cattle, and that 

 no dairyman be permitted to sell milk from a herd containing any untested cows. 

 Glanders received considerable attention from the State board of health (pp. 54-61). 

 Attention was called to the insidious nature of glanders and the danger of infection 

 of other horses as well as human attendants from the presence ox one glanderous 

 animal. 



In a study of hog cholera (pp. 62-82) many data were obtained regarding the con- 

 ditions under which this disease prevails most extensively. In certain cases of this 

 disease it was found possible to isolate Bacillus suisepticus from the lungs and spleen, 

 and B. cholerse mis and B. coli communis from the spleen, as well as P>. coli communis 

 from the kidneys. It is concluded from a study of this disease that the association 

 of swine plague and hog cholera bacilli is of common occurrence, and that swine 

 plague bacilli may be the only organism demonstrable in the initial stages of some 

 cases. In one case hog cholera bacilli were found in salted pork which caused 

 severe digestive disturbances in human beings. Notes are also given on trichinosis 

 (pp. 83-85) and various hog diseases of uncertain origin (pp. 86-88). 



Hemorrhagic septicemia in cattle receives a thorough consideration (pp. 89-115). 

 The authors investigated 91 outbreaks of this disease in cattle in a number of herds 

 including 2,850 animals. The mortality was above 95 per cent. The chief lesions 

 as shown post-mortem, are small and large hemorrhagic areas in the subcutaneous 

 tissues, muscles, and throughout the internal organs. From cases of the disease 

 B. boviaepticus was isolated and was shown to be pathogenic for rabbits and cattle. 

 In controlling the disease no medicinal treatment is of avail. The dead animals must,
