suits of the tests were generally unsatisfactory. See also a previous note (E. S. 

 R., 22, p. 186). 



A catechism on bovine tuberculosis, H. L. Russell and E, G. Hastings 

 (Wisconsin Sta. Circ. Inform. 23, pp. 24, figs. 8).— This circular, arranged in the 

 form of a catechism, is designed for use by those desiring information on tuber- 

 culosis, its cause, effect, and mode of distribution, the mode of application and 

 interpretation of the tuberculin test, and tuberculosis control. 



Experimental studies in regard to the etiolog'y of tumors, S. Lowenstein 

 {Beitr. Klin. Chirurg., 69 (WW), No. S, pp. 693-700, pis. .',, figs. S; ahs. in Zenihl. 

 Biocliem. u. BiopJiys., 11 (1910), No. 1, pp. lit, 15). — If inflammation and swell- 

 ing are present, epithelial cysts can be produced experimentally. They do not 

 possess a pi-ogressive character, and, therefore, do not conform to the Cohnheim- 

 Ribbert theory. 



The author was also able to produce hemorrhages in the bladder, such as 

 occur in papilloma of the bladder, by injections of benzidin. 



About the antigenic properties of tumor lipoids, G. Izar (Ztschr. Immiini- 

 tdtsf. u. Expt. Titer., I, Orig., 7 (1910), No. 5, pp. 62.'i-628).— The activity of 

 megatheriolysin increases up to 55° C, after which it decreases until 70° is 

 reached. At 75° the activity again increases until the boiling point is reached. 



The technique of the meiostagmin reaction with malignant tumors, M. 

 AscoLi and G. Izab (Miinchen. Med. Wchnschr., 57 (1911), No. 41, pp. 2129- 

 2131; al)s. in Cliem. Ahs., 5 (1911), No. 2, p. 320). — The iwwdered tumor is 

 macerated for 24 hours with methyl alcohol at 50° C, shaking occasionally 

 during the period. The mixture is filtei'ed off hot, cooled, and filtered again. 

 The antigen is prepared as usual — 0.1 cc. of a 1 : 100 to 1 : 200 aqueous emulsion 

 to 9 cc. of the serum, which has been previously diluted 20 times with 0.85 per 

 cent sodium chlorid solution. The influence of different acids and salts on the 

 reaction are noted. See also a previous note (E. S. R., 24, p. 780). 



The meiostagmin reaction in foot-and-mouth disease, A. Ascoli (Deut. 

 Med. Wchnschr., 36 (1910), No. 43, pp. 1997-1999; abs. in Chem. Abs., 5 (1911), 

 No. 2, p. 320). — ^When a specific antigen (virus) was added to the blood serum 

 of animals having foot-and-mouth disease, an increase in the surface tension of 

 the serum was noted. This was greater than when the same addition was made 

 to normal serum. The positive reaction is present some time after recovery 

 from the disease. 



Some diseases of swine, N. S. Mayo ( Virginia 8ta. Bui. 189, pp. 3-19, 

 figs. 6). — Following a brief account of simple sanitary precautions and inex- 

 pensive shelter houses, the author discusses swine mange, swine lice (Hceniat- 

 opinus stiis), "bull nose" or necrotic stomatitis, chronic pneumonia or cough- 

 ing, hog cholera, and paralysis in swine, including preventive measures and 

 remedies. 



[Note on a nematode from the stomach of the pig], Foster (Ahs. in 

 Science, n. ser., 33 (1911), No. 850, pp. 590, 591). — Notes are presented on the 

 occurrence of Spiroptera strongylina (or a new species) in the United States. 

 A second species (Physoccphalus sexalatus) that was found associated with 

 8. strongylina is recorded from the United States for the first time and this is 

 also said to be the first record of its occurrence in the domestic pig. 



Is there any danger of disseminating hog erysipelas by immunizing with 

 cultures of the organism causing this disease? AV. Pitt (Berlin. Tierdrztl. 

 Wchnschr., g7 (1911), No. 6, pp. 98-103). — This is a polemical article, in which 

 the author states that Rickmann's conclusions " in regard to Lorenz's serum-
