VETERINAEY MEDICINE. 877 



Canker of pigs is clue to a mange mite. The disease may be treated with car- 

 bolic acid, iodin, or a solution of tobacco. 



Intestinal parasites in hogs may be expelled by the use of a mixture of spigelia 

 and senna, wormseed, cedar apples, areca nut, or turpentine. Two teaspoonsful 

 of turpentine may be given in milk twice dally. 



Conditions which render the mucous lining of the digestive tract perme- 

 able to bacteria, J. Bassett and H. Carre (Coixpt. Rend. hioc. Biol. [Paris], 62 

 (1907), Nu. 11, PI). 890, S91). — The experiments reported in this paper were 

 carried out on 20 dogs, which were given doses of podophyllin in order to cause 

 irritation of the digestive mucosa. 



In 18 of the 20 dogs positive identification was made of intestinal bacteria in 

 the blood of the portal vein, in the chyle, or in both. The bacteria were cocci, 

 .staphylococci, and streptococci, such as are found in the intestines of normal dogs. 

 It appears, therefore, that any irritation such as is set up by the use of podo- 

 phyllin is sufficient to render the alimentary tract permeable to ordinary intesti- 

 nal bacteria. 



A preliminary note on neutral red reaction in the infected red cells of 

 protozoal diseases, F. S. II. Baldrey and W. A. Mitchell [Jour. Trap. Vet. 

 8ci., 2 (1907), No. 2, pp. 169-171, pi. 1). — In the use of neutral red an excellent 

 means has been found for demonstrating protozoa in blood corpuscles after the 

 digestive action set up in such cases has led to the production of an acid cytase. 

 The method may be used successfully both in cases of red blood corpuscles, the 

 substance of which is being digested by parasitic -protozoa, and in white blood 

 corpuscles which are digesting enclosed protozoa. Illustrations are given of the 

 results of applying this method in a study of Piroplasma can is. 



The effect of glycerin upon tuberculous lesions, V. Galtier (Jour. Med. Vet. 

 (t Zoolccli., 58 (1907), 21a ij, pp. 263-266). — Tuberculous organs, including lungs, 

 livers, spleens, etc., when completely submerged in glycerin for periods of 8 to 

 18 months become entirely sterile. An immersion of 7 months is usually suf- 

 ficient to destroy the virulence of tubercle bacilli. The bacilli are gradually 

 attenuated, as shown by inoculation experiments made with them after they had 

 been kept in glycerin for a few days. 



Bovine tuberculosis, L. Van Es (Xorth DaJcota Sta. Bill. 77. pp. 379-430, pis. 

 11). — A discussion is presented of tuberculosis in its varied relations to animal 

 industry and human health. Particular attention is given to bovine tubercu- 

 losis, including its lesions, prevalence, distribution in the body, cause, symp- 

 toms, and diagnosis, the tuberculin test, the economic importance of tuberculo- 

 sis, and the methods of eradication. A brief bibliography of tuberculosis is 

 also given. 



Tuberculosis in swine, W. J. Kennedy et al. (Iowa >Sta. Bui. 92, pp. 2Jf, 

 figs. 2). — The experiments recorded in this bulletin were undertaken for the 

 purpose of determining the effect of feeding pigs skim milk containing tubercle 

 bacilli, as compared with pasteurized skim milk. The pigs used in the experi- 

 ments numbei'ed 40 and were divided into 4 equal lots. Two lots received 

 pasteurized milk, one on pasture and the other in a dry yard. The other 2 lots 

 received tuberculous milk, one on pasture and the other in a dry yard. All of 

 the pigs which were fed tuberculous milk became infected and also 2 of the 

 pigs which received pasteurized milk. 



It appears that tuberculosis is not readily spread among pigs by mere prox- 

 imity of diseased to healthy animals. The authors conclude that tuberculous 

 milk is almost sure to infect pigs, while milk pasteurized at a temperature of 

 200° F. is a safe feed. Pigs confined in clean dry yards are apparently no more 

 susceptible to tuberculosis than those which are kept at pasture.
