184 EXPERIMENT STATION EECORD. 



The anatomy, biology, and pathological effects of Ixodes reduvius, C. K. 

 Beinarovich (Arch, ^'ct. Xuiik [St. J'cfcrsb.]. J7 {lO'Jl ) . Xo. i. pp. 1-Jf3. figs. 

 S). — The life history of Ixodes rciliirliis is described in detail with particular 

 reference to its agency in transmitting the blood parasite of Texas fever in 

 Russia. This tick is a common parasite on cattle in Russia and is believed by 

 the author to be the carrier of the blxxl parasite of Texas fever. Occasionally 

 affected cattle are seen without ;iny evidence of the tick, but the author believes 

 that this is explained by assuuiiug that such cattle had been previously bitten by 

 ticks which had subsequently become engorged with blood and fallen to the 

 ground. 



The curative treatment of mammitis in cattle, G. P. Moretti (Clin. Vei. 

 [Milan], 30 (1907). Xu. 12, pp. 193-196). — The frequency with which mammitis 

 appears in high-bred cows makes it desirable that practical means be devised for 

 tbe treatment of this disease. The author reports good results from pumpiug 

 filtered air into tbe affected quarter of the udder and upon giving hypodermic 

 injectious of chlorid of caffein combined with tbe administration through the 

 mouth of iodid of potash in 20-gm. doses and the application of blisters to the 

 outside of the udder. 



Further notes on Piroplasma mutans — a new species of piroplasma in 

 South American cattle, A. Tiieiler (-lour. C<»npur. Path, and Thcr.. 20 iVJOJ), 

 Xo. 1, pp. 1-lS, pi. 1). — The author has continued his investigation of Firoplasnia 

 higcniUium and /'. mutans. It appears from this study tbat animals which have 

 recovered from Texas fever may be successfully inoculated with P. mutans at 

 any subseijuent date. This is considered as conclusive evidence that the two 

 species are distinct. The author's observations in Cape Colony indicate that 

 while the blue tick is instrumental in transmitting P. hlgeminum from one 

 animal to anotbcr. it does unt carry /'. mutans. At present it is not certain 

 how tbe latter bl(H)d parasite is transmitted. It appears to be distribiited widely 

 over S<mtli Africa and Madagasca.r. 



Control of rinderpest, G. K. Xeso.m (Philippine Bur. Agr. Press Bui. 0. pp. 

 ■'i-l ) .- — A serious outbreak of rinderpest occurred among the cattle and carabao 

 of Occidental Xegros. The method of simultaneous inoculation proved very 

 effective in its control, but the presence of surra and septicemia made it dan- 

 gerous to continue this work except in localities where the last-named diseases 

 did not prevail. In all, 5,780 cattle and carabaos were inoculated, and of this 

 number only 4 per cent subsequently died of rinderpest. 



Septic pr^eunionia of calves, Schkeiber (Monatsh. Prakt. Tierhcilk., 18 

 (1901), Xo. 6-7, pp. 299-329).— 'n\e literature relating to this subject is crit- 

 ically discussetl in connection with a bibliography of 81 titles. The symptoms 

 and etiology of the disease are described, and notes are given on the results 

 obtained from the use of a method of vaccination. The micro-organism which 

 causes the disease is Bacillus rituliscpticus. The vaccination method recom- 

 mended by the author has given satisfactory results in nearly all cases, and con- 

 sists in the use of septicidin. 



Cysticercus tenuicollis in sheep, F. Clutterbuck (Jour. Dcpt. Agr. West. 

 Aust., 15 (1907). Xo. 3, pp. 20J,-20G, pi. i).— The life history of Tania marginata, 

 which is the adult form of the sheep bladder worm, is reviewed and suggestions 

 are made regarding the inspection of mutton for the presence of the bladder 

 worm and the treatment of dogs in order to prevent the further spread of this 

 parasite. 



Gid in sheep, E. J. Dommerhold (Tijdschr. Vecartsenijk., 3.'f (1907), Xo. 

 6, pp, 37.'i-3S2). — This disease, which occurs quite commonly in sheep and cat- 

 tle, and sometimes in goats, may be cured by the removal of the parasitic worm
