to tleterniiiu' the i>ei'centa.i,'e of ergof which could Ite present ui oats considered 

 merchantable according to the law. The committee organized and carried out 

 two sets of experiments in feeding known quantities of ergot to 10 healthy 

 liors«»s. 



In tlie first set of experiments 2.5 gm. of ergot were added daily to 5 kg. of 

 healthy oats and fed to the horses. The effect of feeding this amount of ergot 

 daily for (i weeks was not marked in any of the horses in respect to weight, 

 temperature, heart beat, or respiratory action. The committee were unani- 

 nuuisly agreed on the fact that no effects were observed that could be definitely 

 attributed to ergot. 



Another set of experiments was carried out during which the horses received 

 from 2,5 to 5 gm. of ei'got daily. The results in this case were likewise of a 

 negative character, and it appears that the quantity of ergot normally found in 

 oats can scarcely be considered a serious matter. 



Means of protecting' veterinarians in the examination of glanderous horses, 

 A. I. Spasski {Arch. Vet. Nauk, [St. Petersh.], 31 {1901), No. J,, pp. 32J,, 

 325). — A brief description is given of a mask to be worn over the face and of 

 other apparatus to be worn on the hands in order to protect the observer from 

 possible infection with glanders during the examination of horses. 



Septicemia hemorrhagica in mules, E. C. Webb {.Jour. Compar. Path, and 

 Tlier., 20 {1901), No. 2, pp. 91-100). — Occasion was had to study a number of 

 serious cases of disease in mules in India. The post-mortem lesions were those 

 of acute septicemia and cultures almost ])ure were obtained of the organism of 

 liemorrhagic septicemia from diseased horses and mules. It is believed, there- 

 fore, that these cases were instances of true hemorrhagic sei)ticeniia. This 

 disease has heretofore ))eeu considered rare in both horses and nuiles. 



Biliary fever in dogs, D. Hutcheon {Agr. Jour. Cape Good Hope, 30 {1901), 

 No. 6'. pp. IG.'i-ll'i ) . — A general historical account is presented of the investiga- 

 tion of this disease in South Africa. It has been shown conclusively that it is 

 carried by HamophysaUa IcacM and that the blood parasite which causes it 

 is rirop1a.sin(( caiiis. The symptoms and post-mortem findings are briefly dis- 

 cussed. A preventive vaccine has not been devised. Some benefit is derived 

 from the administration of calomel and quiuin to diseased dogs, and infestation 

 by ticks may l>e to some extent pre\ented by treating the dogs' legs with oily 

 substances which may repel the ticks. 



Leucocytozon canis, S. R. Christophers {Sci. Mem. Med. and San. Depts. 

 India, n. ser., 1906, No. 26, pp. 16, pi. 1; 1901, No. 28, pp. 12, pi. l).—Leucocy- 

 tozoon canis belongs to the hemogregarines and reproduces itself by the forma- 

 tion of true cysts containing each about .30 sporozoits. Encystment takes place 

 in the cells of the bone marrow. After escaping from the cysts tlie sporozoits 

 invade the mononuclear cells in the marrow. The parasite is essentially one 

 of the bone marrow. It is probably carried by the dog tick, flea, mosquito, or 

 some species of Hippobosca. In fact the development of the parasite has been 

 followed by the author in the body of Rhipicephalns sanguineus. 



A parasite found in the white corpuscles of the blood of palm squirrels, 

 W. S. Patton {Sci. Mem. Med. and Sanit. Depts, India, n. ser., 1906, No. 24, PP- 

 13, pi. 1). — Hemogregarines of the type studied by the author were previously 

 known only as parasites of cold-blooded animals. The species studied by the 

 author is described as new under the name Leucociitozoon fiinanihiili and is 

 piirasitic in the blood of Funa)nhul)(s pcnnantii. The i)arasite is found in the 

 body of a louse belonging to the genus Hematopinns commonly observed on the 

 s(|uirr('l.
