and Methods of Eradicating Cattle Ticks, by L. A, Klein ; and 2 papers presented 

 at the meeting in February, 190S, one by A. J. Payne on Cattle Tick p:radica- 

 tion, and the other by M. R. Powers on Tick Eradication Work in South 

 Carolina. 



Amakebe: A disease of calves in Uganda, D. Bruce et al. (Proe. Roy. Soc. 

 [Londo),], Scr. B, 82 {1910), No. B 555, pp. 256-272, pi. 1, figs. i5).— Since the 

 disease of calves called amakebe is East Coast fever, very many of the cattle 

 in T'ganda are almost immiuie to this disease. Owing to its nature, however, 

 whereby animals recovered from the disease are no longer infective, some 

 calves may escape attack and so remain susceptible. This occurs with the 

 calves of the Sesse Islands, which when transferred as grown-up cattle to the 

 mainland mostly die of East Coast fever. The carriers of East Coast fever— 

 Rhipicephalus appendiculatiis (or brown tick). R. evertsi (or red-legged tick), 

 and R. .nmus — are all common in Uganda. 



Contribution to the etiolog-y of epizootic white scours in calves, T. Kraust- 

 STRiNK (Ztsclir. Iiifch-tioiisknntk. u. }Ji/<j. Haufitiere, 7 {1910), Xo. 3-1/, pp. 

 256-263). — The author has examined 73 calves during the last 2 years, 9 of 

 which were affected with the so-called white scours. From their blood and the 

 various organs he isolated a diplococcus (which had a great resemblance to the 

 human pneumococcus) and in pure culture. The pathological findings, how- 

 ever, did not give a definite diagnosis. 



In S of the cases there were apparently some changes on the umbilicus, which 

 led the author to assume that the infection was through the umbilicus. Infec- 

 tion tests with small animals and calves (per os, per umbilicus, and intra- 

 venously) showed that the organism isolated was pathogenic for calves, and 

 produced symptoms and pathological changes which were characteristic of 

 white scours. The organisms retained their pathogenicity for calves for three- 

 quarters of a 5'ear, and even after cultivating on artificial media. Immunizing 

 tests were conducted, but the results were negative. 



Veterinary notes. — Diseases of sheep, T. W. Cave {Jour. Southeast. Agr. 

 Col. Wye, 1908, No. 17, pp. 40t--i2l). — Three papers are here presented, the first 

 on " Struck " Sheep Experiments, in 1007-8 ; the second on An Investigation 

 into the Nature and Cause of " Sway-back " In Lambs, and the third on Some 

 Parasites of the Fourth Stomach and Intestines of Sheep and Cattle. 



A disease of sheep in Tasmania, J. A. Gilruth (Vet. Jour., 66 {1910), No. 

 420, pp. ,355-36.'i). — The author reports bacteriological investigations of the dis- 

 ease previously noted (E. S. R.. 23, p. 1851). 



I. Mediterranean fever experimentally produced in sheep. II. Passage of 

 Micrococcus nielitensis from the mother to the fetus in experimentally in- 

 fected ewes, A. Conor {Compt. Rend. Soe. Biol., [Paris], 68 {1910), No. 13, pp. 

 678-680). — Data presented show that sheep are susceptible to subcutaneous 

 inoculation and to ingestion of cultures of .1/. melitensis and that the infection 

 may be transmitted through their milk. An experiment reported shows that 

 Af. melitensis can traverse the placental barrier and pass from the mother 

 to the fetus. 



Notes on a protozoan parasite found in the mucous membrane of the aboma- 

 sum of a sheep, J. A. Gilrutii {Bui. Hoc. Path. E.iof., 3 {1910), No. 5, pp. 297- 

 299. pi. 1). — Cysts found by the author in the abomasum of Tasmania sheep 

 are thought by Mesnil, to whom a specimen was submittetl, to be a schizogonic 

 stage in the evolution of some parasitic sporozoan of the sheep. Having 

 found sarcosporidia to be very common in sheep, cattle, and goats in Australia, 

 the author suggests the possibility of the cyst being a stage in the evolution 

 of Sarcocystis. In an appended note Mesnil gives a brief account of investiga- 

 tions since made in ]jis laboratory by Chattou, who found those cysts to occur
