VETERINARY SCIENCE AND PRACTICE. 301 



this disease are briefly discussed, with special reference to recent outbreaks of the 

 disease. 



Serum therapy in foot-and-mouth disease, E. Nocard {Jour. Agricole [Par/.s], 

 14 {1903), No. 161, pp. 137-141)- — This is a copy of the report made at a general 

 agricultural congress in Paris. The method of applying this treatment is outlined 

 and the advantages and disadvantages are mentioned. It is stated that the immu- 

 nity persists for not longer than 15 days, and that at the end of that time the animals 

 are as susceptible to the disease as before treatment. 



The serotherapy of foot-and-mouth disease, E. Nocard {Bui. Ayr. Alger ie et 

 Tunisie, 9 {1903), No. 12, pp. 215-280). — Brief notes are given on the successful 

 application of serotherapy in the treatment of various diseases of animals and man. 

 In the treatment of foot-and-mouth disease the results from the use of serum have 

 been much less satisfactory, but the author believes that a more lasting immunity 

 will ultimately be produced by this method. 



Report on the cattle disease in southern Rhodesia, R. Koch {Ayr. Jour, and 

 Mill. Rec. [Natal], 6 {1903), Nos. 10, pp. 313-319; 12, pp. 401-405).— KcdLTQlwl investi- 

 gation of the virulent form of Texas fever, or red water, which has long been known 

 in Rhodesia, led the author to the conclusion that this disease, while closely related 

 to Texas fever, is quite distinct from it. 



The author observed a number of constant differences between Texas fever and the 

 form of the disease which prevails in Rhodesia. In the latter form of the disease the 

 red blood corpuscles are more abundantly infected with the blood parasites, but 

 the destruction of the blood corpuscles is very slight as compared with that which is 

 observed in cases of Texas fever. It was only in a few instances that the number of 

 red blood corpuscles per cubic millimeter was reduced to 4,500,000. 



An examination of animals dead of the Rhodesian fever discloses certain post-mor- 

 tem changes which are absent in cases of Texas fever. These changes consist in 

 lesions in certain organs which indicate that parasites become accumulated in these 

 parts in enormous numbers. In a number of ca.ses it was possible to determine 

 definitely that the animals were simultanously affected with Texas fever and 

 Rhodesian fever. The small parasites of the Rhodesian, or African Coast fever, as 

 the author calls it, were present in the blood, together with larger pyriform organisms 

 of Texas fever. 



Another striking difference between Texas fever and Rhodesian fever was observed 

 in the fact that direct inoculation of healthy animals with the blood of animals 

 affected with Rhodesian fever does not produce infection from the first inoculation 

 but only after a second inoculation. It was observed that the animals which were 

 immune to Texas fever were very subject to Rhodesian fever, but it was found pos- 

 sible to produce immunity to the Rhodesian form of the disease by inoculation with 

 the blood of animals infected by this form. 



The cattle disease in southern Rhodesia, R. Kocn {Transvaal Agr. Jour., 1 

 {1903), No. 4, PP- 112-117). — A circumstantial account is given of the conditions 

 which prevail in the infested territory. The symptoms of the Rhodesian tick fever 

 are said to be very similar to those of Texas fever. The rate of mortality is very 

 high, in some outbreaks 80 to 90 per cent. The blood parasites are considerably 

 smaller than in the case of Texas fever and in the early stages of the disease are not 

 very numerous. The destruction of red corpuscles is by no means so great as in 

 Texas fever. There is therefore a much less pronounced anemia than is usually 

 observed in Texas fever. Extensive experiments have been planned for the purpose 

 of developing a successful method of inoculation and the author hopes for satisfactory 

 results from these experiments. 



The Rhodesian tick fever, A. Theiler {Transvaal Agr. Jour., 1 {1903), No. 4, 

 pp. 93-110, pi. 1). — The name "Rhodesian tick fever" is proposed to differentiate 

 this form of protozoan disea.se from the less malignant Texas fever of the United
