typical reaction with all the methods. Forty-seven animals were slaughtered, 

 of which 5 gave no reaction at all and showed no lesions of tuberculosis. 

 Another animal, which reacted to all tests, also showed no lesions. No animal 

 gave the subcutaneous reaction alone. 



The difficulties encountered in the diagnosis of tuberculosis by tuberculin, 

 A. Eloibe {Rcc. M6d. V^t., 90 (1913), No. 2, pp. 61-66).— A description of cases 

 in which difficulties were encountered in pronouncing animals tubercular on 

 the basis of the tuberculin test. 



The limitations of the tuberculin test, E. G. Hastings (Amer. Vet. Rev., 

 Jf2 {1913), No. 4, pp. 38.'fS9S). — This article discusses especially the points 

 where the tuberculin reaction may be misinterpreted, and also the difficulty of 

 eliminating tubercular cattle from a herd on the basis of the test. 



Tuberculosis, J. McFadyean (Jour. Roy. Agr. Soc. England, 71 (1910), pp. 

 27-.'/5). — This deals with the hereditary factors concerned in the causation of 

 tuberculosis and their elimination from herds. 



Immunization ag'ainst hemorrhagic septicemia, J. R. Mohleb and A. Eich- 

 HORN (Amer. Vet. Rev., 1,2 (1913), No. //, p-p. -^OS-^IS).— Previously noted from 

 another source (E. S. R., 28. p. 2S1). 



Hemorrhagric septicemia in the sheep in Scotland, J. P. McGowan and T. 

 Rettie (Jour. Path, and Bact., 17 (1918), No. 3, pp. Jf2S-/{25; Vet. Jour., 69 

 (1913), No. JfSS, pp. lOJt-107). — The authors suggest that at least some of the 

 cases which go by the name of " braxy " may in reality be cases of this disease 

 (pasteurellosis). 



Contagious agalactia of the sheep and of the goat, H. Carr6 (Ann. Inst. 

 Pasteur, 26 (1912), No. 12, pp. 937-972, pis. 3; abs. in Jour. Compar. Path, and 

 Ther., 26 (1913), No. 1, pp. 55-59). — Brief reference is first made to the litera- 

 ture relating to this disease, the majority of the references being the work of 

 Italian authors. In some districts the disease is an actual scourge, especially 

 in the mountainous districts. It is of much economic importance, as it occa- 

 sions great loss of condition and renders the animals unsuitable for slaughter, 

 and in sheep there is atrophy of the mammary gland. Acute and chronic forms 

 of the disease are recognizable and there are symptoms of a general and of a 

 local nature. 



The author finds that, contrary to the opinion held by other authors, infected 

 udders are capable of secreting for months a liquid of constant virulence, even 

 up to the time of total atrophy of the gland. The disease is contagious only 

 when " open " lesions are present. The lachrymal secretion from diseased 

 eyes is infective even though there be no actual ulceration. The principal 

 method of infection is by ingestion. A large amount of the virus in a state of 

 purity can be obtained by producing pleurisy experimentally. The serum of 

 hyperimmunized animals has protective properties. Serovaccination as prac- 

 ticed at the laboratory promises to be of great prophylactic value. 



About the precipitation reaction in hog erysipelas, M. Isabolinsky and B. 

 Patzewitsch (CentU. Bakt. [etc.], 1. AM., Orig., 67 (1912), No. 4, pp. 284- 

 288). — Ascoli's reaction, using a specific erysipelas seioim, is specific, but all 

 erysipelas sera do not give uniform reactions. The reaction can be employed 

 where the organs are in a state of putrefaction and is even more specific. The 

 most definite reaction is obtained with the spleen and heart. Disinfecting 

 agents do not affect the results providing they are carefully removed from the 

 infected material. 



A case of pustular dermitis and pyemia in the horse, caused by Micrococ- 

 cus tetragenus, L. Mongeell (Ann. MM. V6t., 62 (1913), No. 3, pp. 151-154; 

 abs. in Vet. Rec., 25 (1913), No. 1293, pp. 650, 651).— A report of a case at 

 Brussels, the pus of which in addition to staphylococci showed the presence of
