cases), acute encephalitis (2 cases), heat apoplexy (1 case), neuroparalysis 

 (1 case), hemorrhage of the spinal cord (1 case), and in founder (1 case), 

 the author found toward the end of the disease and also shortly before death 

 a more or less marked increase in the number of erythrocytes and amount of 

 hemoglobin. In petechial fever (3 cases), however, a decrease was found both, 

 in the number of erythrocytes and in the amount of hemoglobin. 



A bibliography of 62 titles is appended. 



The diagnosis of glanders by the precipitation method, W. Pfeiler (Arch. 

 Wiss. It. Prakt. Tierhcilk., 35 (1909), No. Jf-5, m). 323-337; abs. in Vet. Rec, 22 

 {1910), No. 1130, p. 588; Berlin. TierdrztJ. Wchnschr., 26 {1910), No. 7, p. 

 155). — The author employed two tests for this purpose, the mixing test (in 

 which the serum to be examined is mixed with the precipitinogen reagent) and 

 the strata or layer test (where if a horse serum is covered with a laj-er of 

 distilled water, salt solution, or carbolic-salt solution tliere appears at the 

 point of contact a gray-white ring which simulates the ring which appears 

 when specific precipitins are present). There were 452 samples of blood exam- 

 ined, amongst which were 306 from glander suspects or from animals which 

 were presumably exposed to the infection. All the cases were further con- 

 trolled by either the complement binding reaction or the agglutination test. 



From the results it is concluded that the deviation of complement reaction 

 allows the detection of old and new cases, while the agglutination test will 

 detect new cases but will not show cases where the disease has been of long 

 duration. The precipitation test was always positive with recent cases and 

 in most instances with old cases, and in only two cases were the results 

 negative. 



The prevention of strangles, Desoubry {Bui. iioc. Cent. Med. Tel., 87 

 {1910), No. 2, pp. J,9-56; ahs. in Jour. Compar. Path, and Ther., 23 {1910), 

 No. 1, pp. 87-91). — During an outbreak of this disease 30 cc. of anti-sti"angle 

 serum was systematically injected into every healthy animal which had been 

 exposed to infection and within a few hours of birth into all the foals born 

 afterwards, and the disease stamped out. Since 1907 injections of serum have 

 been given from the time of birth with the intention of preventing the dis- 

 ease, remarkable results being obtained. Among 650 animals which received 

 injections from April 1, 1907, to May 31, 1909, not a single case of strangles 

 was observed, although these were at places where the disease ordinarily 

 occurred. 



" The plan adopted in using Dassonville's serum as a protective agent, and 

 the one which gave the best results, was to give a dose of 20 cc, (1) either 

 at the time of birth or shortly after, on the following day or later; (2) when 

 the foals, at about 6 months old, left the principal establishment for weaning, 

 and had to be sent to stables at a distance; (3) at the time when they went 

 a:way for training, when it was most important that they should be in the 

 best of health to bear the strain that would be put upon them; (4) when an 

 outbreak of strangles occurred in a stud, in order to immunize, if not already 

 too late, those that had been exi)0sed to infecti<m." 



The relation of fowl diphtheria to contagious epithelioma, G. Schmid 

 {Centbl. Bakt. [etc.], 1. AM., Orig., 52 {1909), No. 2, pp. 200-23-',, figs. 2; abs. 

 in Hyg. Rundschau, 20 {1910), No. 10, pp. 545, 5'f6). — The results are given of 

 an investigation with 60 cockerels and S3 hens from which the author con- 

 cludes that it is possible to produce typical pock lesions in chickens having 

 diphtheria, and further, that bird pox is not a separate disease but a part of the 

 diphtheria and has the same etiology. Fowl diphtheria occurs in 3 forms: 

 That affecting the mucous membrane, that affecting the skin, and a combina- 

 tion of the two.
