Poisoning from ground sesame cakes, Deyerling {D<mt. Thier- 

 drztl. Wchnschr., 8 (1900), No. 5, ^>/>. 73, 7^).— The author makes a 

 report upon the symptoms and circumstances of poisoning in the case 

 of 111 cattle from eating* ground sesame cake. The animals had pre- 

 viously been fed small quantities of this substance, together with other 

 fodder materials. At 5 o'clock in the afternoon all these animals 

 received 1^^ l))s. of ground sesame cake in the place of cotton-seed meal. 

 The animals also received quantities of sugar-beet leaves and hay and 

 straw. About 15 minutes after feeding one animal was observed to 

 be bloated, and within a short time all the animals manifested the same 

 symptoms. These symptoms included tympanites, coughing, and diffi- 

 cult breathing. The animals all recovered. 



In order to make sure that the ground sesame cake was the cause of 

 the trouble the author obtained permission to experiment furthei" with 

 this substance. A few of the animals were fed ground sesame cake in 

 addition to the regular ration which all received. The same s^'mptoms 

 were developed as ])efore. 



African horse sickness, J. McFadyean {Jour. Comj). Path, and 

 Ther., 13 {1900), JVo. 1, pp. 1-20). — The author makes a report on 14 

 experhuents for the study of the symptoms, etiology, and treatment 

 of this disease. It was shown that the pathogenic organism readily 

 passes through the pores of the Berkfeld or Chamberland F. filter, 

 even when they are suspended in liquids containing a considerable 

 amount of albumin. The experiments carried out by the author indi- 

 cate that the disease may be transmitted to healthy horses by hj^po- 

 dermic inoculation with the fresh blood of a diseased horse, and also 

 by intrcxlucing the material into the stomach. It would appear that 

 under normal conditions the disease is most frequently transmitted by 

 ingestion of the virus. So far as the author's observations go, it seems 

 probable that the disease is not ordinarily acquired by inhalation. 



The pathogenic organism of this disease has been called tedemamyces 

 and has been believed to be a facultative parasite which is able to mul- 

 tiply rapidly outside of the animal body under favorable conditions of 

 heat and moisture. It is believed by some that the organism is fre- 

 quently taken into the body by eating dew-laden grass, but there is 

 ver}^ little evidence to sustain this belief. 



An elevation of temperature is the first s3nnptom of infection by the 

 African horse sickness. This rise of temperature takes place in from 

 •i to 7 days after inoculation and is not accoiupanied by rigor. In 

 5 cases of the disease produced experimentally, death occurred on the 

 eighth day. The duration of the disease appeared to be the same in 

 cases produced by inoculation and in those produced b}^ ingestion of the 

 virus. Detailed notes are given on the pathological anatomy in cases 

 of death from this disease.
