VETERINARY MEDICINE. 583 



The sediment obtained, which consisted of practically only acid-fast bacilli, was 

 dried in a Heira-Faust apparatus. The dried pulverent material was termed 

 " enteritidin " by the authors. Sero-diaguostic tests with " enteritidin," using 

 a suspension of this preparation as an antigen for the complement fixation 

 method, resulted negatively with the serum obtained from cows having infec- 

 tious intestinal catarrh. 



In order to test the therapeutic value of the preparation 2 calves (Nos. 5 and 

 7) were given 100 mg. in a physiological salt solution intravenously. Two 

 other animals, one sound (No. 6) and the other (No. 122) having an infectious 

 catarrh of the entire alimentary tract, were given 100 mg. per os. Calf No. 6 

 was killed after 3 months' time and found to have a chronic intestinal catarrh. 

 Calf No. 5 was destroyed 10 months after the injection, and although the mucosa 

 of the alimentary tract seemed to be somewhat thickened no acid-fast bacilli 

 could be detected in the mesenteric lymph nodes. A few organisms were found 

 in the mucosa of the small intestine after an extended search. One year after 

 the infection calf No. 7 was killed, but no bacilli could be detected in either 

 the mucus membranes or in the mesenteric lymphatic glands, although when 

 subjecting the tissues to the action of antiformin a few bacilli were noted. 

 Three other animals, one infected and two healthy, were vaccinated intrave- 

 nously with 100 mg. of the preparation, but these tests are not completed. 



Some tests on the transference of infectious intestinal catarrh from mother to 

 offspring through the agency of feces were also included, which show that 

 without doubt the disease can be acquired during the suckling period. 



In regard to sheep pox in Tunis and the attenuation of the virus by heat- 

 ing-, E. DucLoux {Compt. Rend. Soc. Biol. [Paris], 72 (1912), No. 7, pp. 279- 

 281; abs. in Centhl. Bakt. [etc.], 1. Ait., Rcf., 53 (1912), No. 8, p. 238).— Sheer) 

 pox is enzootic in North Africa and causes many deaths among sheep, chiefly 

 young sheep, during the rainy season. An attenuated vaccine v/hich will pro- 

 duce the disease only at the site of injection can be prepared by heating virus 

 in a water bath. All sheep intended for export were formerly treated with 

 antipox serum. 



Experimental investigations in regard to hog cholera, P. Uhlenhuth 

 (Centhl. Bakt. [etc.]. 1. Aht., Orig., 64 (1912), Festsehrift F. Loeffler, pp. 1.51- 

 165). — This is a critical review of work done on hog cholera luider the direc- 

 tion of the author at the Institute of the Royal Health Department at Berlin. 

 A comparison was made with the work of other investigators. 



Hog cholera, C. D. McGilvkay (Amer. Vet. Rev., Jfl (1912), No. .;, pp. JfJfff- 

 Jt-i9). — An outbreak occurred at Kenora, Manitoba, which involved 146 hogs. 

 All of the animals were slaughtered. The results of the investigation in 

 regard to the source of the disease furnished strong circumstantial evidence in 

 support of the belief that it started by feeding uncooked swill or kitchen refuse 

 which contained pork or pork products. 



A preliminai'y report on the action of china berries, leaves, and blooms on 

 pigs, C. A. Cary (Auier. Vet. Rev., Jfl (1912), No. .}, p. 455). — Preliminary tests 

 of the action on pigs of these materials have led to the following conclusions: 



" The berries, leaves, and blooms all produce intoxication in pigs. Somewhat 

 prolonged feeding of the berries will produce distinct fatty degeneration of the 

 kidneys and liver. There are other changes, but these are the most prominent." 



Helminthes parasitic in equines, R. T. I/eiper (Vet. Jour., 68 (1912), No. 

 446, pp. 4G9-472). — This is a classified list of the nematodes, trematodes, and 

 cestodes parasitic in equines, including 56 species representing 12 families and 

 17 genera.
