bronchi, and cases of intestinal lesions are eliminating them with the drooliugs 

 from the mouth and with the feces. 



" The presence of tubercle bacilli in milk seems to be accounted for by tuber- 

 culous udders and from contamination of the milk with the feces. When these 

 facts are applied to the milk situation it seems fair to assume that if the cows 

 in the dairies producing milk for the market were carefully and frequently 

 examined for evidence of the disease and all those found to be thus affected 

 were excluded the number of samples of market milk containing tubercle 

 bacilli would be greatly reduced if they did not entirely disappear." 



The author states that a careful and often repeated physical examination of 

 infected herds and the removal of all suspicious cases will check to a large 

 extent the spread of the disease to other animals in the herd and will minimize 

 the number of bacilli in the milk, thereby protecting the consumer. However, 

 to prevent the interherd spread of the disease tuberculin must be properly 

 applied to all cattle coming into sound herds. 



The International Commission's recommendation on eradication, a full report 

 of which has been previously noted (E. S. R., 25, p. 384), is appended to the 

 bulletin. 



The elimination of tubercle bacilli from infected cattle, V. A. Moore {Jour. 

 Med. Research, 2Jf (IDll), No. 3, i)p. 517-525).— ^oted above. 



The treatment of contagious granular vaginitis in cattle, A. Laszlo (Vet. 

 Jour., 67 (1911), No. JfSff, pp. //S//, ^85).— The author has obtained successful 

 results from the use of " Bissulin," a mercury preparation. 



Experimental prophylaxis for distomiasis, A. Railliet, G. Morrssu, and A. 

 Henry (Com,pt. Rend. Soc. Biol. [Paris], 70 (1911), No. 11, pp. 425-J,27 ) .—In 

 tests made of the resistance of the ciliated larvae of the liver fluke to various 

 chemicals used as fertilizers, etc., including gypsum, lime, iron sulphate, and 

 the nitrates, sulphates and chlorids of potassium and sodium, it was found that 

 the larvai were manifestly more susceptible to the action of sodium salts than 

 to those of potassium. Agricultural lime, however, was found to be the most 

 destructive agent tested, immediate destruction following the use of 3 gm. of 

 lime to a liter of water, or, 0.75 parts in 1,000. In order to be effective liming 

 should be done in the spring or in summer. 



In experimenting with small undetermined species of snails, it was found that 

 they were destroyed when exposed for 5 minutes to a solution of 0.5 parts of 

 lime in 1,000. 



Experimental treatment of distomiasis, A. Railliet, G. Moussu, and A. 

 Henry (Com-pt. Rend. Soc. Biol. [Parisl;, 70 (1911), No. 11, pp. J,27-Ji29).— In 

 the attempt to destroy the liver fluke while in the liver, the authors used aloes, 

 calomel, sodium salicylate, and boldo. The greater number of the animals 

 affected were benefited by the treatment, but the parasites were not destroyed, 

 as was determined at post-mortem examination. Other experiments in which 

 phosphorated oil, arsenic, atoxyl, dioxydiamidoarsenobenzol, trypanblue, ben- 

 zoate of mercury, and fluid extract of genista (scoparius) were employed, were 

 without positive results. 



Researches on the treatment of distomiasis of the sheep, A. Railliet, G. 

 Moussu, and A. Henry (Compt. Rend. Acad. 8ci. [Paris], 152 (1911), No. 17, 

 pp. 1125-1127; Rec. MM. Y6t., 88 (1911), No. 9, pp. 283-289; Vet. Reo., 2ff 

 (1911), No. 1200, pp. 17-19). — Sevei'e losses of cattle in France during the early 

 months of 1911 led to the investigations of the liver flukes here reported. 



In attempting to And an agent that will destroy the flukes in the bile ducts, 

 the authors experimented with aloes, calomel, sodium salicylate, " boldo," tartar- 

 emetic, urotropine, and atoxyl. with negative results. They were more success- 

 ful in experiments with ethereal extract of male shield fern.
