tain precautions necessary for obtaining reliable results in the tuberculin test, es- 

 pecially in regard to avoiding conditions which tend to cause a rise in temperature. 



Piroplasmosis and anaplasmosis in Turkey (1916), W. Stefko {Bui. Soc. 

 Path. Exot, 10 {1911), No. 8, pp. 723, 724).— During the summer of 1916 the 

 author observed piroplasmosis and anaplasmosis in many cattle from Russia 

 in Trebizond, Platana, Rizeh, and elsewhere In Turkey. The percentage of 

 fatal cases was very high, from 80 to 90 per cent. Smears from the spleen 

 showed the presence of Piroplasma higeminurn, P. anniilatum, and Anaplasma 

 centrale, a double infection occurring very frequently. The cattle tick is the 

 intermediate host concerned. Ixodes corniger and Rhipicephalus simus occur 

 but are not so widely distributed. 



A disease in cattle in the Philippine Islands similar to Anaplasma mar- 

 ginale, W. H. Boynton {Philippine Agr. Rev. [English Ed.], 10 {1917), No. 2, 

 pp. 119-127, pis. 3, fig. 1; Philippine Jour. Sci., Sect. B, 12 {1917), No. 6, pp. 

 281-291, pis. 3, fig. 1). — In an investigation made of a disease of three native 

 cattle which arrived at Manila from Batan Island, bodies were found in the 

 red blood cells that were similar to A. marginale, as described by Theiler and 

 Sieber (E. S. R., 26, p. 882), and one of the cows presented the symptoms and 

 lesions of anaplasmosis. The heart's blood of this animal was injected sub- 

 cutaneously into a supposedly susceptible bull, but the blood had no effect upon 

 this animal that could be determined, either physically or by blood examination, 

 during a period of 228 days. 



Contagious abortion of cattle, H. Welch {Montana Sta. Circ. 61 {1917), 

 pp. ^l-JfS, fig. 1). — A popular summary of information. 



The avenue of invasion and the behavior of the infection of contagious 

 abortion in the uterus, W. L. Williajis {Jour. Amcr. Yet. Med. Assoc., 52 

 {1917), No. 1, pp. 13-38). — A paper presented at the annual meeting of the 

 American Veterinary ISIedical Association at Kansas City, Mo., in August, 1917. 



While the original portal of entry of the abortion infection into the system 

 in most cases of natural infection requires further study, the evidence at 

 present points to two great sources (1) the inti-auterine infection of the fetus 

 and (2) contaminated milk fed to the new-born calf. 



Bovine onchocerciasis in Argentina, M. Pi^tee {Bol. Min. Agr. [Argentina's, 

 21 {1917), No. 1, pp. 35-41, figs. 16). — Onchocerca bovis is thought to be the 

 species which causes this affection of cattle in Argentina. See also a previous 

 note (E. S. R., 37, p. 80). 



Tuberculous mastitis in the cow: Its pathogenesis and morbid anatomy 

 and histology, J. M'Fadyean {Jour. Compar. Path, and Ther., 30 {1917), Nos. 

 1, pp. 57-77; 2, pp. 139-172, pi. 1, figs. 39).— This is a general discussion of 

 the subject with a review of the literature. 



Coccidiosis of calf, L. B. Bates {Proc. Med. Assoc. Isthmian Canal Zone, 8 

 {1915), pt. 1-2, pp. 92-9^). — The author reports upon the occurrence of cocci- 

 diosis in a calf which came in contact with rabbits affected with the same 

 disease and thought to have been caused by Eimeria stiedw. 



Parasites affecting sheep, C. P. Fitch {Cornell Vet., 7 {1917), No. 4, pp. 

 233-254, figs. 4)- — A summarized account. 



The control of hog cholera, with a discussion of the results of field ex- 

 periments, A. D. Melvin and M. Dorset {U. S. Dept. Agr. Bui. 584 {1917), pp. 

 18, figs. 2). — This is a review of control work with hog cholera which has been 

 carried on by the department in cooperation with State officials. While no 

 feasible plan has yet been devised for the complete eradication of hog cholera, 

 it is deemed entirely possible to control the losses from the disease, thus plac- 

 ing hog raising upon a relatively stable basis, freed for the most part from 

 the hog-cholera menace.
