Alterations in the character of the anthrax bacillus, G. Scagliosi (Centbl, 

 Unit, [etc.'], l. .I/-/., Orig.,S? I 1904), No. ■'■■ pp.649 654). Amhrax bacilli and spores 

 have been preserved by the author on sterilized threads since L894. 



The action of diffused light upon the anthrax organism was found to be very slight, 

 ,.\. n after a lapse of 10 years. The agglutinative action was also little affected. 

 Inoculation experiments Bhowed thai the virulence of the bacilli is almost asgreal as 

 that of fresh cultures. From the author's experiments it appears thai char 

 temperature are more important than any other factors in modifying the virulence 

 ami other characters of anthrax cultures.

Texas fever cattle tick: Pasture methods of eradication, II. A. Morgan 

 , Tennessa Sta. Bui., Vol. XVIII, No. /. />/>. 10). — A general account is given of the 

 flistribution of the cattle tick, immunity to Texas fever, and the national quarantine. 

 The life history of the tick is carefully described with special reference to methods 

 pf its eradication. En eradicating the ticks a pasture rotation system may be used, 

 excluding cattle, horses, and mules from jpastures from June to October, inclusive, 

 and thus starving out the ticks, or the feed Lot system may be adopted. 



Experimental transmission of African coast fever by means of ticks, A. 

 Tiu:ii.i:h (Fortschr. Vet. Hyg., 2 (1905), No. 10, pp. W7-268). — An elaborate account 

 is presented of the appearance, development, and habits of various ticks which occur 

 in s,.uth Africa. Experimei ta wore made to determine the possible agency of these 

 ticks in different stages in transmitting African coast fever. 



In these experiments Rhipicephalus decoloratus, /«'. simus, /.'. appendiculatus, R. 

 evertsi, and Hyalomma xgyptium were used. From a result of the author's experi- 

 ments it is concluded that African coast fever is transmitted by Rhipicephalus appen- 

 Hculatus and R. simus. The first species is the most important, and adult ticks, of 

 which the nymphs sucked virulent blood, are chiefly concerned in carrying infec- 

 tion. The other species of ticks may be disregarded, with the possible exception of 

 Amblyomma hebraeum, with which the author made no experiments. 



It appears that a tick can produce infection only once. African coast fever is to be 

 expected throughout South Africa wherever the intermediate host of Piroplasma par- 



mm is found. 



Some diseases complicating- rinderpest among cattle of India, J. D. E. 

 B.OLMES (Jour. Compar. Path, and Ther., J? | 1904), No. 4, />/>■ 817-826, pi. 1). — As a 

 rule, rinderpest runs a regular course and offers little difficulty in diagnosis. It is 

 often complicated, however, by the simultaneous occurrence of Texas fever, trypa- 

 nosomiasis, echinococcus disease, distomatosis, or foot-and-mouth disease. Notes 

 are given on the symptoms and pathological anatomy observed in such cases. 



The prophylactic treatment of rinderpest by means of preventive inocula- 

 tion, more especially in the conditions prevailing in India, <i. K. Walked 

 your. Compar. Path. and-Ther., 11 I 1904), No. 4, pp. 826-843)- — Considerable diffi- 

 culty has been experienced in inducing the natives of India to apply any curative or 

 preventive remedies against rinderpest. The disease is enzootic in India, and the 

 mortality is not as high as that observed in South Africa and elsewhere. The viru- 

 lence of the disease i- greatest during the cold season, particularly at the com men ce- 

 ment of an outbreak. 



The various methods used in treating this disease are carefully outlined and their 

 advantages and disadvantages are described. These methods include Koch's bile 

 method, the glycerin bile method of Edington, the use of a mixture of bile from 

 different sources, the use of serum alone, and the method of simultaneous inoculation
