918 EXPERIMENT STATION RECOED. 



attended with serious accidents in practice. Double vaccination with pure vaccines, 

 even when very attenuated, is not always safe. Inoculations with a mixture of 

 immunizing serum and virus is attended with accidents and the inmiunization is 

 uncertain. The method which is preferred by the authors consists in successive 

 inoculations with an immunizing serum and a j>ure attenuatcil virus. 



Vaccination for blackleg by means of the thread vaccine, H. George {Bid. 

 Agi: Algerie et Tun isie, 8 ( 190-2), No. ^2,2yp. 548-550 ) . — -A brief account is given of the u.se 

 of the clouble vaccine method in the prevention of blackleg. As compared with this 

 method, that in which vaccine is used on a thread is considered as possessing many 

 advantages in simplicity, safety, and efficiency. 



The preparation of blackleg vaccine, C. F. Dawson [Amer. Ynt. Iter., £6 {1903), 

 No. 8, pp. 76^-767). — Notes are given on the technique employed in the preparation 

 of the virus and vaccine for prevention of the development of blackleg. 



Bovine pasteurellon in the Malay Peninsula, Carrongean {Vet. Jour., 55 

 {i;i02), Xi). S,-iO, })j>. 321-337). — Tlie author makes a report on an investigation of a 

 supposed outbreak of rinderpest in the Malay Peninsula. It was found that the dis- 

 ease was not rinderpest but hemorrhagic septicemia, or bovine pasteurellon. It 

 appears in the Malay Peninsula in a subacute, acute, or chronic form. All forms are 

 due to the same organism, an ovoid pasteurella. The organism varies greatly in 

 virulence. Preliminary experiments give promise of good results with a method of 

 preventive inoculation. 



"Peste," C. NocKOLDs {Anwr. Yet. Rer., 26 {190-2), Xo. 5, j>p. 411-415). —"Veste" 

 is said to l>e a native term for rinderpest. This disease is reported as having almost 

 exterminated the domesticated animals in various parts of the Philippines. Notes 

 are given on l)acteri()logical studies of material obtained from investigating the 

 disease. 



Texas fever and its relation to the live-stock interests of Tennessee, W. 

 C. Rayen (.Jour. Comp. Med. and Vet. Arch., -23 {1902), Xo. 10, pp. 625-630). — The 

 irregular distribution of the cattle tick in Tennessee and the fact that this State lies 

 on the boundary between the tick-free and infested j^ortions of the country causes 

 considerable complication in proper enforcement of sanitary measures with regard 

 to Texas fever. It is stated that some portions of Tennessee lying south of the 

 quarantine line are entirely free from ticks and that cattle may therefore be safely 

 shipped from such localities to Northern States. The desirability of rational legis- 

 lation based on careful examination of the territory concerned is advocated. 



Some notes on redwater, .1. Hewson {Vet. Jour., 55 {1902), Xo. 328, pp. 207- 

 209). — Brief notes are given on the appearance of this disease in certain localities. 

 In 1 herd of 13, 10 were affected during the course of 3 weeks. 



Rhodesian redwater, F. Hutchinson and P. D. Simmons {Ayr. Jour, and Min. 

 Rec [Xatall, 5 {1902), Xo. 20, pp. 663-670). — The authors present a summary account 

 of observations made on trips of inspection through the country infested with this 

 disease. Notes are given on the po-st-mortem appearance and clinical symptoms of 

 the disease and on the practical methods which have thus far been found effective in 

 controlling redwater. 



The Rhodesia form of redwater, H. Watkins-Pitchford {Agr. Jour, and Min. 

 liec. [Xatal^, 5 {1902), Xu. 19, pp. 597-600). — Brief notes are given on the peculiarly 

 virulent form of redwater in Rhodesia and on the experiments which have already 

 been conducted for devising means of controlling the disease. 



Oil-water pumps for spraying cattle to destroy ticks, C. P. Lounsbury {Agr. 

 Jour. Cape Good Hope, 21 {190-2), Xo, 5 , pp. 427-434, pis. 2) . — The description is given of 

 a number of different makes of pumps designed for producing a mechanical mixture 

 of kerosene and water. Some difficulty is experienced with the use of all these 

 pumps in obtaining a mixture of uniform strength. The question of the comparative 

 value of dipping and spraying is liriefiy discusse<l. While in Australia dipi)ing has
