Tierdrztl. WchnscJir., 55 {1911), No. 29, pp. /,89, ^90).— The most effective rem- 

 edy for the removal of Ascaris megalocephala from the horse, according to the 

 author, cousists of giving from 15 to 20 gm. of tartar emetic in fractionated 

 doses as foUovv^s : The tartar emetic is dissolved in a bucketful of water and 

 one-third of it is given at 6 o'clock in the morning (water being withheld 

 from the animals since the night previous), the second third at 8 o'clock, and 

 the last at 8.30. After this treatment cathartics are usually unnecessary, but 

 feeding beets or bran may aid the process considerably. 



A contribution to the knowledge of the occurrence and development of 

 Sclerostomum edentatum, O. Martin {Arch. Wiss. u. Prakt. Tierheilk., 37 

 {1910), No. 1-2, pp. 106-151, pi. 1, figs. 2).— Following a brief review of the 

 literature, the author reports upon investigations of the biology of S. edentatum, 

 its infestation of equiues of different ages, etc. 



Of 426 horses examined in the course of a year at the Hamburg abattoir 214 

 were found to be infested by this nematode. In these horses the worms were 

 found in the subserosa of the parietal peritoneum in 139 cases and in the large 

 intestine in 180. They were found both in the intestine and beneath the 

 parietal peritoneum in 105, beneath the parietal peritoneum alone in 34, and in 

 the intestine alone in 75 cases. Of 495 additional horses in which only the 

 subserous tissue of the parietal peritoneum was examined 162 were infested. 



A bibliography of 41 titles is included. 



Notes on ovarian infection with. Bacterium pullorum (Rettger) in the 

 domestic fowl, G. E. Gage {Jour. Med. Research, 24 {1911), No. 3, pp. ^91- 

 496). — B. pullorum was isolated from the ovaries of 3 domestic fowls and in 

 some instances in pure culture. 



From one of the cases 12 ova were used for preparing agar and bouillon cul- 

 tures, which were tested as regards virulency as follows: "Eighty-two chicks 

 which had been incubated under proper conditions were used for this test. 

 Sixty-two were inoculated, 30 by subcutaneous injections of a small amount of 

 a bouillon culture of Bacterium pullorum, and 32 received 2 drops of a bouillon 

 culture of the organism by the mouth. These inoculations were made at the 

 end of 24 and 48 hours respectively. The remaining 20 healthy chicks were 

 kept under the same conditions as the inoculated chicks. Every chick in the 

 check lot was alive and healthy at the end of 6 weeks when this test was con- 

 sidered concluded," while 60 of the 62 infected birds died. 



A post-mortem examination of each chick was made, and according to the 

 author the results obtained corresponded well with Rettger and Stonebum's 

 pathological findings (E. S. R., 25, p. 590). He believes that there can be no 

 doubt that B. pullorum is the causative agent for white diarrhea in chicks. 

 The organism was reisolated in each instance. 



About transferable fowl leukemia, H. Hibschfeld and M. Jacoby {Berlin. 

 Klin. Wchnschr., 46 {1909), No. 4, pp. 159, 160; abs. in Zenthl. Gesam. Physiol, 

 u. Path. Stofftvechsels, n. ser., 5 {1910), No. 9, pp. 356, 357).— The results of 

 tests with 2 diseased fowls which presented the typical leukemic symptoms 

 are reported. The blood from these animals was transferred through 4 genera- 

 tions, and- in each instance the blood of the inoculated animal showed the 

 typical picture of leukemia and contained tubercle bacilli. It is concluded that 

 even tubercle bacilli can bring about an enormous increase in certain leucocytes 

 in the blood which reminds one of leukemia. 



In regard to an epizootic of an unknown chicken disease, M. Eggebbecht 

 {Ztschr. Infektionshranlc. u. Hyg. Haustiere, 5 {1909), No. 5, pp. 453-458; ais. 

 in Berlin. Tierdrztl. Wchnschr., 26 {1910), No. 5, p. 116).— Along with chicken 

 cholera there occurs yearly in Tsingchau, China, an acute febrile disease which 

 causes a large mortality among chickens. It is caused by an ultravisible filter-
