300 EXPERIMENT STATION RECORD. 



In further experiments 100 cc. of milk was placed in each of 8 flasks, which were 

 then sterilized on :\ consecutive days. Four of tlie flasks were inoculated with the 

 same quantities of micro-organism B, and after 48 hours were again sterilized. The 

 8 flasks were then inoculated with a culture of micro-organism A, great care being 

 taken to secure practically the same number of micro-organisms in each flask. The 

 4 flasks winch had been inoculated with micro-organism B gave very uniform results, 

 as did also the 4 flasks not inoculated v ith this micro-organism. Between the 2 sets, 

 however, there was marked variation. The acidity developed much more rapidly 

 in the first instance. At the end of 24 hours the number of bacteria in the flasks 

 without the influence of micro-organism B was 12,920,000 per cubic centimeter, and 

 in the flasks previously inoculated with micro-organism B, 517,920,000. 



Micro-organism B, therefore, exerts an influence upon the development of micro- 

 organism A as is shown by the visible changes brought about in the milk, by a study 

 of the development of acid, and by determinations of the number of bacteria present. 

 The results indicated that this influence is due to the products of micro-organism B. 

 The work is believed to have a direct bearing on the subject of pure-milk supply, and 

 is to be continued.

VETERINARY SCIENCE AND PRACTICE. 



Report of the colonial veterinary surgeon for 1902 (Cape Town: Govt. Printer, 

 1903, pp. 28).— An outbreak of rinderpest occurred in Basutoland for the first time in 

 2 years. Attention is called to the necessity of thorough destruction of all centers of 

 infection for this disease. Both bile and serum are used in preventive inoculation 

 against the disease in Cape Colony. The chief advantage in favor of bile is the fact 

 that it can be prepared with less skill and more quickly than serum. Serum is more 

 effective, however, and cheaper. Notes are also given on pleuro-pneumonia, tuber- 

 culosis, inspection of dairies and abattoirs. Reports from the assistant veterinary 

 surgeons are also presented. 



Abattoirs and meat inspection in Holland, Kuhnau (Berlin. Tierarztl. Wchn- 

 schr., 1904, No. 37, pp. 625-630). — The organization and execution of meat inspection 

 in Holland are briefly described with notes on their different abattoirs. Statistics 

 are presented on the number of animals inspected and on the precentage of animals 

 found to he affected with tuberculosis, trichina, and other diseases. 



Diseases of domestic animals (Japan in the Beginning of the 20th Century. To- 

 kyo: Imperial Japanese Commission to the Louisiana Purchase Exposition, 1904, pp. 196- 

 199).— A brief review is presented of the origin of animal diseases in Japan with 

 especial reference to cattle plague, anthrax, glanders, black leg, pseudo-farcy, foot- 

 and-mouth disease, and rabies. The status of veterinary practice is also briefly dis- 

 cussed. 



A brief report of veterinary literature concerning wounds for the year 

 1901-2, E. Bass (Deut. Tierarztl. Wehnschr., 12 (1904), No. 37, pp. 368-371).— The 

 literature of this subject is critically discussed in connection with a bibliography of 

 51 titles.

 eral pathology and pathological anatomy for the year 1903, O. Barbacci
