1112 EXPERIMENT STATION RECORD. 



experiments in feeding new-born animals with virulent cultures of anthrax and tuber- 

 culosis, as well as with certain proteids. 



In all cases great care was exercised not to injure the mucous membrane in any 

 way so that the infection which followed could be attributed to the permeability of 

 the intestinal walls for the bacteria in question. The experimental animals were 

 guinea pigs and rabbits. By means of tubes and pipettes it was found possible to 

 measure in a very accurate manner the amounts of bacterial cultures fed to the ani- 

 mals. During these experiments it was found that the anthrax bacillus leaves the 

 alimentary tract very readily. 



Within 6 hours after feeding the feces contained anthrax bacilli in large numbers, 

 while after 17| hours they were to be found only in isolated cases. The anthrax 

 bacillus, however, did not lose its virulence in passing through the alimentary tract. 

 It was found that young guinea pigs could be fed very large quantities of virulent 

 anthrax bacilli without causing any infection. Even spore-bearing cultures failed 

 to be pathogenic. When these experiments were carried out according to the 

 requirements of von Behring the guinea pigs remained in perfect health. 



In experiments with tubercle bacilli the results were quite different. Within a 

 few days after feeding large quantities of tubercle bacilli, some bacilli were found in 

 the glands of the omentum and liver. When only small quantities were fed, how- 

 ever, the tubercle bacilli could not be found in the glands. Apparently the bacilli 

 passed through the walls of the alimentary tract very rapidly. In certain stages of 

 the process, especially in the cecum and vermiform appendix, sections were made of 

 this material and examined microscopically. Notes are also given on .the permea- 

 bility of the intestines for hemolytic serum, casein, albumen from hens' eggs, and 

 various antitoxins. 



Bacillus necrophorus and its economic importance, J. B. Mohler and G. B. 

 Morse ( U. S. Dept. Agr., Bur. Anim. Indus. Circ. 91, pp. 76-116). — This is reprinted 

 from the annual report of the Bureau for 1904 (E. S. B., 17, p. 702). 



Report of the chief inspector of stock, R. E. Weir {Jour. Dept. Agr. West. 

 Aust., 12 (1905), No. 6, pp. 527-531). — An account is given of the present gov- 

 ernment veterinary staff of Western Australia. Brief mention is also made of the 

 prevalence of pleuro-pneumonia, tuberculosis, hog cholera, and Texas fever among 

 animals as well as poisonous plants. The author discusses the present status ol 

 horse, cattle, and sheep raising and gives brief notes on the condition of pastures, 

 abattoirs, and the registration of brands. 



Books, memoirs, and articles on tuberculosis, Bouchez (Rev. Tuberculose, 2. 

 ser., 3 (1906), No. 1, pp. 98-120). — A classified bibliography is presented of litera- 

 ture relating to tuberculosis in man and animals. The books and articles referred to 

 are grouped under natural classes according to the organs affected by tuberculosis 

 and into general groups — hygiene, pathology, therapeutics, experimental veterinary 

 medicine, etc. 



Cattle tuberculosis, H. Sessions ( New York: W. R. Jenkins, 1906, 2. ed., pp. 777-4- 

 120). — This edition has been practically rewritten and brought up to date by the 

 addition of much new material, particularly with reference to the recent discoveries 

 relating to tuberculosis in cattle. The subject-matter in the volume includes an 

 introduction and chapters on human tuberculosis as related to bovine tuberculosis, 

 cause of the disease, symptoms and diagnosis, tuberculin test, milk inspection, meat 

 inspection, disposal of tuberculous carcasses, and insurance of cattle intended for 

 slaughter. 



Danger of infection with, tuberculosis by different kinds of exposure, 

 E. C. Schroeder and W. E. Cotton (U. S. Dept. Agr., Bur. Anim. Indus. Circ. 83, 

 pp. 44-65). — This is reprinted from the annual report of the Bureau for 1904 (E. S. R.,
