408 EXPERIMENT STATION RECORD. 



the condition of the animal became considerably worse after an intravenous injection 

 of colloidal material. The body temperature rose and the laryngeal glands showed 

 excessive swelling. A subsequent niallein test indicated the presence of glanders, 

 the temperature rising to 40.6° C. The disease was also transmitted to an attendant, 

 in whom it resulted fatally. 



Contagious abortion in cattle (Bd. Agr. and Fisheries [London], Leaflet 10$, pp. 

 14). — Simple or sporadic abortion is described for the purpose of distinguishing it 

 from the contagious form of the disease. Brief notes are given on the results 

 obtained by the internal administration of carbolic acid and the external use of 

 various antiseptics in the treatment of this disease. 



As a result of these experiments it is recommended that all aborting cows should 

 be isolated and no longer used for breeding purposes. Sheds should be treated with 

 a lime wash every 3 months and the parts of the buildings which can not be reached 

 may be sprayed with some other antiseptic. All cows in the herd should be treated 

 externally with some antiseptic solution. For this purpose the author recommends 

 Izal, 1 part to SO parts of water. 



African coast fever, W. Robertson {Agr. Jour. Cape Good Hope, 25 (1904), No. 

 ,), j>p. 262-268, />!. t,figs. 15).— The symptoms, post-mortem occurrence, cause, and 

 means of infection of this disease are briefly described. The disease may be trans- 

 mitted through the agency of the brown tick and the black-pith d tick, but chiefly 

 by means of the former. The inoculation method devised by R. Koch is said to have 

 proved ineffective in practice. Attention is directed to the importance of proper 

 fencing and dipping for the destruction of ticks. Infested animals may be freed from 

 ticks by dipping in kerosene and various arsenical and other dips. 



Distribution of coast fever ticks, C. P. Lounsbiry (Agr. Jour. Cape Good Hope, 

 25 (1904), No. 3, pp. 268-270, pi. 1). — The distribution of Rhipicephalus appendicu- 

 lotus, R. simus, I!, evertsi, and R. c<i]>ciu<is is briefly outlined, with an account of the 

 agency of the first 2 spe< -ies in the distribution of African coast fever. 



The sheep fluke, N. A. Cobb (Agr. Gaz. New South Wales, 15 (1904), No. 7, pp. 

 658-669, fig. 1). — Attention is caUed to the agency of birds, especially ducks, in the 

 destruction of snails which may carry the intermediate stage of liver fluke. These 

 birds must, therefore, be considered as of some importance in the control of liver- 

 fluke disease. Occasionally the liver fluke is found in the liver of the kangaroo, hare, 

 rabbit, and wallaby, but nearly always in small numbers. 



During the author's investigation of this subject it was found that the extent of 

 infestation by liver flukes may be accurately estimated by a determination of the 

 number of eggs in the excreta. The eggs are distributed in a uniform manner in the 

 excreta of the sheep. It is necessary to carry on further experiments in order to 

 determine the variation in a number of eggs due to age, breed, kind of feed, and 

 length of infestation. 



Infectious diarrhea in lambs, D. Hctcheon (Agr. Jour. Cape Good Hope, 25 

 (1904), No. 3 pp. 281-283). — A study of several outbreaks of this disease in lambs 

 led to the conclusion that the disease is due to a pathogenic organism which gains 

 entrance to the young animal through the navel cord at the time of birth. The 

 disease may most successfully be prevented, therefore, by antiseptic treatment. 



Official treatment of swine plague, F. Glage and C. Nieberle (Fortsclir. Vet. 

 JJyg., 2 (1904), No. 6, pp. 161-167). — Brief statements are made regarding the regu- 

 lations of the veterinary police in various parts of Prussia with reference to swine 

 plague. The authors discuss the value of these regulations in controlling the disease. 

 With regard to the carcasses of infected hogs the authors held the opinion that the 

 meat is not injurious to health and need not be considered of inferior value except 

 in cases of great emaciation or jaundice as a result of the disease. Further experi- 

 ments are required to determine the harmful or harmless character of the milk of 

 infected hogs.
