injection per rectum, as in erysipelas, tuberculosis, and anthrax, it was enter- 

 ogenous. Two cases of tuberculosis showed an infection in the pharyngeal and 

 bronchial lymphatic glands. 



A simple reaction for tuberculosis, P. Bermbach (Ztschr. Tuberkulose, 16 

 (1910), No. 3, p. 209). — This test is based on the fact that lecithin when added 

 to an emulsion of horse leucocytes is hemolytic, and further that the blood 

 serum of noncachectic and nonfebrile cases of tuberculosis contains lipoid-like 

 substances. 



Tuberculosis, A. T. Peters (Nebraska Sta. Rpt. 1909, pp. 42-52). — The author 

 states that 281 farms reported by the Bureau of Animal Industry as sending 

 tuberculous stock to the Omaha market were located in 55 counties, 47 of these 

 being reported for swine tuberculosis, 41 for tuberculosis in cattle, and 33 for 

 both cattle and hogs. It is pointed out that tuberculosis, both among cattle and 

 swine, is confined largely to one center in the State. 



In dealing with the disease, much has been accomplished through the medium 

 of a reading club composed largely of farmers and stockmen throughout the 

 State. A sample of the questions sent to members of this club, with answers, 

 is appended to the account. 



Of 3,602 head of cattle from 63 herds that were tested with tuberculin, 3.68 

 per cent reacted. The practice of breeders in allowing their hogs to follow 

 cattle is considered by the author to be responsible for a large percentage of 

 the disease in hogs. Sixtj'-six of the 281 farms reported are said to have 

 cleaned up their herds, either by using the tuberculin test, or by sending their 

 animals to the abattoirs subject to inspection. 



A mixed infection of coccidiosis and pseudotuberculosis in cattle, G. Bugge 

 and H. Sach (Berlin. Tierdrztl. Wchnschr., 26 (1910), No. 33, pp. 6Ji9, 650).— 

 A description of a case in a milch cow, which later came to slaughter and 

 autopsy. 



Abortion in cattle, A. T. Peters (Nebraska Sta. Rpt. 1909, pp. 37-41).— 

 Mention is made of accidental abortion and a brief accoimt given of the symp- 

 toms, cause, treatment, etc., for contagious abortion. 



The author's investigations show that medicinal treatment has little or no 

 effect on sterility resulting from contagious abortion. " Out of 209 animals 

 that were apparently sterile, 86 remained sterile in the herd for a year or more, 

 41 for 18 months or more, while conception occurred in 11 which successfully 

 gave birth to a calf. Post-mortems were held on 74 of these animals and all 

 were found to have diseased ovaries, 42 out of the 74 having one ovary affected 

 while 32 had both ovaries affected." 



Observations on the blood pressure of sheep, M. Dresbach (Amer. Jour, 

 Physiol., 25 (1910), No. 7, pp. 433-438; abs. in Zentbl. Biochem. u. Biophys., 10 

 (1910), No. 12-13, p. 596). — The average blood pressure in the carotid artery of 

 the sheep was found to be equivalent to 110 mm. of mercury. 



History of hog* cholera experiments in Nebraska, A. T. Peters (Nebraska 

 Sta. Rpt. 1909, pp. 111-124). — The author reports briefly upon hog cholera in- 

 vestigations conducted at the Nebraska Station since those reported in 1898 

 (E. S. R., 9, p. 93). He does not consider the swine plague bacillus to be in any 

 way serious in the production of disease in swine; while it can be found in 

 most animals affected with hog cholera, it may be compared to colon bacilli 

 which are almost always found in cases of typhoid and yet do not produce 

 typhoid fever. 



Hogs which had recovered from hog cholera and were placed in a hog cholera 

 pen and there exposed in various ways were found to be immune against the 

 disease, as were also their litters. It is stated that several of a lot of sows 

 (not immune through natural cholera) which were vaccinated with 20 cc. of
