Veterinary notes, T. W. Cave (Jour. Southeast. Agr. Col, Wye, 1912, No. 21, 

 pp. 439-453). — These notes relate to struck sheep experiments; parasitic pneu- 

 monia of sheep due to the red lungworm (StrongyUts rufcficens), a disease allied 

 to "husk," which is caused by the lung threadworm (EustrongyUts filaria) ; 

 parasites of the fourth stomach of cattle; tuberculosis in cattle and the new 

 tuberculosis order; and the death of fowls from impaction of the crop, due to 

 improper feeding. 



The behavior of new serum and liver substances, and levulosuria in 

 trypanosomiasis, K. Schern {Berlin. TierarztJ. Wchnschr., 29 {1913), Xo. 40, 

 pp. 710, 711), — Continuing previous work," the author sought to determine 

 whether the substances capable of reviving or extending the life of trypano- 

 somes, such as exist in normal serum, were present in other parts of the normal 

 animal organism. Very labile trypanosomes, taken at the third stage of the 

 infection, were treated with organ pastes. 



Liver and serum were found to have an elective position in this regard. 

 These substances were found to be very stabile so far as boiling and drying 

 were concerned, and they could be preserved for a long time in a refrigerator 

 at a temperature of 37° C. The activities of this substance or substances are 

 suppressed by putrefaction. 



From the liver aud serum a substance was prepared in which the reviving 

 and life-extending principles were present in concentrated form, and which after 

 a period of 4 years was still active. Although these principles are present in 

 the serum and liver of diseased animals, they seem to diminish toward the end 

 of the disease. They are absent in the sera of rats in the third stage of the 

 disease. The fresh liver of a rat which died from trypanosomiasis contamed 

 the active principle only in a minimum quantity. The possible relation of this 

 principle in other diseases, as glanders, tuberculosis, anthrax, typhoid, and 

 cholera, is also discussed. 



Some intraperitoneal injection tests with levulose showed that infected rats 

 in the third stage of the disease will discharge the levulose with the urine. 

 Animals in the first and second stages of the disease did not eliminate levulose. 



Tuberculous contagion by dried particles, P. CHAUSsfi (Rec. Med. V6t., 90 

 {1913), No. 15, pp. 497-511).— This deals with the history of the subject and 

 criticizes Cornet's theory. It discusses especially tuberculosis caused by inha- 

 lation. 



About the intracutaneous use of avian tuberculin for diagnosing fowl 

 tuberculosis, L. Van Es {ZtscJir. InfektionskrauJc. u. Ilyg. Jlaufiticre, 14 {1913), 

 No. 4-5, pp. 271-296, pi. 1, figs. 2).— Tuberculosis was noted among the poultry 

 of the North Dakota Experiment Station, and it was decided to study the intra- 

 cutaneous test as to its value for diagnosing tuberculosis in birds. The tuber- 

 culin employed was prepared in the usual manner from the avian tubercle 

 bacillus and was used in a concentration of 50 per cent. In a few cases 100 

 per cent crude tuberculin was used but as it apparently gave weak reactions, 

 its use was discontinued. The points of application were the comb and one 

 of the wattles, and the injections were given as superficially as possible in 

 order to reach the Malpighian layer. A Pravaz syringe having a small-l)ore 

 needle was employed for the injections, and the amount of tuberculin given 

 varied from ^o to io cc. of 50 per cent tuberculin per fowl. 



It is stated that the results can be noted within 24 to 72 hours, but usually 

 48 hours post-injection. The diagnostic feature consists in noting the swelling
