instances. The sera of 99 animals, which had been kept in infected barns but 

 had not given prematux-e births or aborted, showed positive in 28 cases. 



For the intracutaneous reaction 2 preparations were used. These were 

 prepared by concentrating 5 to 6-week-old bouillon cultures of the Bacillus 

 abortus to one-tenth of the volume. For the test 0.2 cc. was taken, and 

 an apparatus called the " cutimeter " was used for measuring the swelling 

 produced. A reaction was considered positive when the difference between the 

 normal and swollen skin amouulcd to 5 mm. Of 30 nouaborting animals, 1 

 showed positive with the test, and with 22 aborting bovines 19 or 20 gave a 

 positive reaction. Among 23 animals which were suspected of being aborters, 

 from 13 to 15 gave positive reactions. Of 53 other animals probably free 

 from the disease 17 gave positive reactions. 



Chronic diarrhea in cattle. — Johne's disease, B. II. Mellon and P. ZnIac- 

 GiNNis (Dept. Agr. and Tech. Inst. Ireland Jour., 13 (1913), No. 2. pp. 311- 

 S2Jf). — The investigation here reported failed to develop a remedy for this 

 disease. 



Concerning' the specificity of ultramicroscopic bodies in contag'ious pleuro- 

 pneumonia in cattle, G. Feeibekger {Ztschr. Infelctionskrank. u. Hyg. Haustiere, 

 12 (1912), No. 5, pp. Ii55-Ii61). — The author's studies led to the conclusion that 

 the ultramicroscopic bodies described by certain investigators as the cause 

 of contagious pleuro-pneumonia are not specific since similar bodies are also 

 found in the blood of heiilthy and diseased men, cattle, and horses. 



Worms in sheep. — Some experiments in treatment, M. Henry {Agr. Gaz. 

 N. 8. Wales, 2.', (1913), No. 2, pp. 116-122).— In drenching experiments in 1910 

 and 1912 with worm-infested lambs in which arsenic, copper sulphate, a pro- 

 prietary drench, and creosote were used, the controls did best with the excep- 

 tion of one lot of lambs treated with arsenic and magnesium sulphate. In 

 other experiments, sheep that were supplied with a lick of calcium phosphate 

 5 parts, sulphate of iron 1 part, and Liverpool salt 40 parts gained much 

 faster in weight during a 3 months' test than did a lot supplied with a 

 similar lick without the calcium phosphate. 



Forage poisoning or cerebro-spinal meningitis, J. R. Mohler (Aiiicr. Vet. 

 Rev., 42 (1913), No. 5, pp. 506-522). — This paper has been previously noted 

 from another source (E. S. R., 28, p. 886). 



Investigations of the clinical appearance of enzootic cerebrospinal menin- 

 gitis (Borna disease) of the horse with an account of therapeutic experi- 

 ments, J. Schmidt {Berlin. Tierdrztl. Wclinschr., 28 (1912), Nos. 32, pp. 581- 

 586; 33, pp. 597-603; ahs. in Cornell Vet., 3 (1913), No. 1, pp. 27-^3).— This 

 report of investigations carried on since 1907 includes a detailed account of the 

 clinical symptoms of the disease, as based upon a study of 415 cases. 



The course run in a large percentage of the cases was from 1 to 2 weeks. 

 Recovery was complete in 6.3 per cent and incomplete in 3.6 per cent of the 

 cases. The symjitoms indicate the presence of disease foci in the essential 

 substance of the cerebrum, cerebellum, medulla oblongata, and the spinal 

 cord, as well as in the cortex of the large brain. 



Therapeutic experiments gave only negative results. ' 



A report on the outbreak of cerebrospinal meningitis (encephalitis) in 

 horses in Kansas and ITebraska in 1912, D. H. Udall (Cornell Vet., 3 (1913), 

 No. 1, pp. 17-43, pis. 5). — The author first reviews at some length reports of 

 investigations relating to the subject. This is followed by a report of the clinical 

 experience of the author and others during the outbreak in Kansas, Nebraska, 

 and neighboring States in 1912.
