1114 EXPERIMENT STATION RECORD. 



Experience with von Behring's method of protective vaccination of cattle 

 against tuberculosis, Schricker ( Wbhnschr. TierheUk. a. Viehzucht, 50 (1906), Xo. 

 7, pp. 121-128). — Von Behring's method of vaccination against tuberculosis has been 

 in practical use for 3 years and the results obtained, therefore, give a good foundation 

 for judging its effectiveness. 



The author vaccinated 76 animals by this method without any bad effects, and on 

 evidence of live tubercle bacilli were found in any of the animals which were subse- 

 quently killed and examined. It is concluded, therefore, that a protective vaccina- 

 tion of calves under 4 months of age is capable of greatly increasing the resisting 

 power toward tuberculosis and in some cases checks slightly the development of an 

 infection already existing at the time of vaccination. 



The prevention of tuberculosis in cattle, J. Wilson (Dept. Ayr. and Tech. 

 lnstr. Ireland Jour., 6 (1908), No. ..', pp. 300-304). — Tuberculosis in cattle according to 

 the author is chiefly spread by means of the air and food. Notes are given on these 

 different methods of infection and on the prevalence of tuberculosis in England. It 

 is estimated that from 5 to 10 per cent of the yearlings in England are infected, 10 to 

 20 per cent of 2-year olds, and 40 to 60 per cent of adult cows. Attention is called 

 to the danger from mammary tuberculosis in cows and to the use of tuberculin and 

 other methods in the detection and eradication of the disease. 



Anthrax, D. Lax (Rev. Facult. Nac. Agron. y Yd., 2. ser., 1 (1905), No. 6, pp. 

 173-176). — Veterinarians in various parts of South America are frequently called 

 upon to deal with outbreaks of anthrax. The author presents a brief account of the 

 course of the disease and of the usual methods of vaccination to immunize animals 

 against it. 



Immunization of the guinea pig and rabbit against anthrax, F. Marino 

 (Compt. Bend. Soc. Biol. [Paris], 60 (1906), No. 6, pp. 306-308).— In the author's 

 experiments it was found possible to vaccinate guinea pigs against anthrax by means 

 of subcutaneous injections of the first vaccine. . It was very difficult to produce 

 immunity, however, by intraperitoneal injections. 



Guinea pigs which withstood repeated subcutaneous injections of a mixture of 

 anthrax and preventive serum from a rabbit or guinea pig frequently failed to resist 

 the minimum mortal dose of the first vaccine. The normal serum of rabbits mixed 

 with virulent anthrax and injected hypodermically into guinea pigs protects them 

 against the disease. 



The pathological anatomy of glanders, Schutz (Ztschr. Yeterindrk., 18 (1906), 

 X<>. 2, />/>. 49-62). — This statement was originally prepared in 1882, for the guidance 

 of army veterinarians in determining cases of glanders and for use in diagnosing the 

 disease from pathological material sent to the veterinary school in Berlin. The 

 article in its present form has been recently revised and brought up to date. 



Observations on normal and rinderpest blood, F. S. H. Baldrey (Jour. Trop. 

 Vet. Sci., 1 (1906), Xo. 1, pp. 47-69). — In a study of the normal blood it is found that 

 the average number of red blood corpuscles was 7,298,484 per cu. mm. The number 

 varied, however, from 5,600,000 to 9,100,000 and the number of leucocytes varied 

 from 8,000 to 18,000. 



In arriving at these averages a large number of counts were made. An examina- 

 tion was also made of the blood of animals which had been bled for the production 

 of a protective rinderpest serum. In these animals it was found that the average 

 number of red blood corpuscles was 3,713,000 per cu. mm. In animals actually suf- 

 fering from rinderpest the number of leucocytes increases rapidly, rising to 32,000 by 

 the fourth day. The relative proportion of the various elements in the blood is dis- 

 cussed for other diseases as compared with rinderpest. 



Redwater in cattle, A. E. Mettam (Dept. Ayr. and Tech. Instr. Ireland Jour., 

 6 (1906), No. 2, pp. 248-260, pis. 3).— This disease, under various names, occurs in 

 North and South America, Africa, Australia, various parts of Asia, and Europe, The
