No. 1, pp. 22S8). — Continuing worlf previously noted (E. S. R., 22, p. 584), tlie 

 authors now report results of further tests with nearly 700 animals. In their 

 opinion the test has now passed the probationary stage and deserves to be 

 adopted as a method for diagnosing suspected cases of contagious abortion.

Experiments to determine the safe dose of white arsenic. Cooper's dip, 

 and bluestone'for sheep, A. Theilee (Agr. Jour. Union So. Africa, 3 (1912), 

 No. 3, pp. 321-351, figs. 2). — The author has conducted a large series of experi- 

 ments on sheep with a view to determining the maximal reliable dose of these 

 drugs and mixtures thereof, which are frequently used in South Africa for the 

 treatment of many diseases of all classes of domesticated stock, but more 

 particularly in the treatment of sheep affected both with wireworms and 

 tapeworms. 



" It appears that arsenious oxid in the dose of 15, 30, and 45 grains is a safe 

 dose for sheep, but it would not be wise to use the largest dose on a gi'eat num- 

 ber of sheep. . , . Cooper's dip administered to sheep in the doses of 15 grains 

 had no fatal effect on 30 sheep. The 15 sheep belonging to the lot of ' watered 

 24 hours previous to and after dosing ' were noticed to be ' off feed ' the day 

 following. With the dose of 30 grains, 48 sheep were dosed and 1 died the 

 day following. . . . The dose of 22 grains bluestone appears to represent a 

 safe dose for sheep; it may probably be slightly increased. The dose of 45 

 grains and more may cause death. . . . The dose of 30 grains white arsenic, 

 mixed with 30 grains of bluestone, does not appear to be a safe dose for 

 sheep. . . . The dose of 15 grains of Cooper's dip, added to 15 grains of blue- 

 stone, given in a mixture, seems to be a safe dose for a sheep. ... A safe 

 dose of a mixture of Cooper's dip and bluestone, when mixed with 2 substances 

 which are considered to bo harmless, such as salt and sulphur, became toxic, 

 and caused death amongst the treated sheep." 



The details of the post-mortem lesions in the 2 sheep which died from poison- 

 ing by arsenious oxid are presented in an appendix. 



The importance of hog' cholera and the production of hog-cholera serum,

 This is a discussion of the history, geographical distribution, pathology, symp-

Protective vaccination against hog cholera, J. Gyabfas {Allatorvosi Lapok, 

 35 {1912), No. 25, p. 291-293; abs. in Berlin. Tierdrztl. Wchnschr., 2S {1912), 

 No. 31, p. 569). — Vaccinations were made with the Hutyra hog-cholera serum 

 and 1,592 hogs. Previous to the vaccination 14 hogs died and the epizootic 

 was considerably advanced. After vaccination 353 animals died. In another 

 locality out of 478 pigs vaccinated 2 died, and in a third bam where the 

 vaccinations involved 507 head the loss was 9.4 per cent. The serum has no 

 curative action according to the author. 



Some investigations in regard to hog erysipelas, immune serum, and its 

 action in the animal body, H. Holth {Maanedskr. Dyrlwger, 24 {1912), No.

 569). — Hog erysipelas immune serum does not possess any bactericidal prop- 

 erties, but contains relatively large amounts of specific agglutinins and ambo-
