Observations bearing on the possibility of developing an experimental 

 chemotherapy of tuberculosis, P. A. Lewis {Bui. Johns Hopkins Hosp., 28 

 (1917). No. 313. pp. 120-125). — This is a general discussion of the subject, to- 

 iiether with experimental data on the disinfectant action of phenol, resorcin, 

 and several organic dyes on the tubercle bacillus. The tubercle bacillus was 

 found to be considerably more susceptible to the action of disinfectants than 

 is ordinarily considered. 



Eradicating' bovine tuberculosis, W. H. Pew (Breeder's Gaz., 11 {1911), 

 No. 19, pp.- 9GS, 970). — The author reports upon the successful eradication of 

 tuberculosis from the Iowa Agricultural College herd by means of the " modified 

 Bang system," suggested by E. C. Schroeder of the U. S. Department of Agri- 

 culture as a possible method for managing a reacting herd with the least 

 cost and minimum loss. 



The cows were maintained absolutely in quarantine, kept in the open winter 

 and suunner, and fed in the open. The calves were dropped in the quarantine 

 pasture and permitted to remain with their dams until weaning time, which 

 was from 6 to 11 months of age. They were then tested, retested in from 

 60 to 90 days, and then taken to the clean herd. Of 21 calves tested that were 

 dropped in quarantine from 1908 to 1914 and permitted to nurse their dams 

 until weaning time IS passed the test and 3 reacted. At the time the quarantine 

 herd was discontinued in 1915, only two animals were left, the others having 

 died or were sold. 



The results tend to show that it is not necessary to discard reacting animals 

 and that calves can be kept with cows in open conditions with a fair degree 

 of safety. Whenever it is found that a cow under this system produces two 

 calves in succession that are reactors at weaning time, it may be suspected 

 that this cow is a contaminating factor through the udder, which is probably 

 affected. 



Sterility of cattle and methods of treatment, J. Albrechtsen (Cornell Vet., 

 7 (1917), No. 2, pp. 57-110). — This account, a translation from the Dani.sh, 

 deals with the subject at length under the headings of treatment of sterility, 

 diseases of the uterus, diseases of the ovaries, cystic degeneration of the 

 ovaries, diseases of the vagina, and results. 



Prevention and treatment of hemorrhagic septicemia of cattle by the use 

 of bacterial vaccine made from the causative agent, T. O. Beandenbukg (Jour. 

 Amer. Vet. Med. Assoc., 51 (1917), No. 1, p. 93). — The use of a vaccine in a 

 number of cases is noted. From the results the author considers the vaccine 

 to be " an absolute preventive if properly used and curative in all cases which 

 are not advanced." 



Two injections about eight days apart are considered necessary to establish a 

 positive protection. Younger animals were found to be more susceptible to the 

 di.sease and also to treatment than older animals. 



Diseases of new-born calves and outline of recommendations for control. 

 W. L. Williams (Cornell Vet., 7 (1917), No. 2, pp. 110-134) .—This article, pre- 

 pared by the author in cooperation with the Bureau of Animal Industry of the 

 U. S. Department of Agriculture, is part of an extensive report upon investiga- 

 tions of contagious abortion of cattle to be published in the annual report of 

 the New York State Veterinary College. 



Anaphylaxis in cattle and sheep, produced by the larvae of Hypoderma 

 bovis, H. lineatum, and CEstrus ovis, S. Hadwen and E. A. Bkuce (Jour. 

 Amer. Vet. Med. Assoc., 51 (1917), No. J, pp. 15-44, figs. 15). — Experiments are 

 reported in which anaphylaxis was produced in cattle, sheep, rabbits, and 

 guinea pigs with extracts of the larvaj of H. lineatum, H. bovis, and O. ovis.
