692 EXPERIMENT STATION RECOED. 



60 cases of carcinoma were examined by the authors, of which 59 were in cows and 

 only one was in a steer. One of the most frequent locations for the beginning of 

 carcinoma in cattle is in the eyelid in cases where foreign bodies enter the conjunc- 

 tival sac through the running of the tear fluid and the motion of the nictitating 

 membrane of the eye. In the study of these cases the authors noted a constant 

 aliscnce of metas^tasis in the deep lymph glands and other organs. 



Sorghum as stock food, W. Thompson ( West Virginia Farm Rev., 8 {1900), No. 9, 

 pj). 287, 288). — This article is reprinted from the Louisiana Planter. The author 

 relates the circumstances of loss of stock from eating sorghum on his own estate, and 

 suggests that the explanation of fatal results from eating sorghum is not to be found 

 in poisonous principles, but rather in the sticky nature of sorghum leaves, which 

 causes them to adhere to the larynx, thus strangling the animals. 



The susceptibility of camels to rinderpest, Tartakowsky [Arch. Sci. Biol. \_St. 

 Petersburg'], 8 {1900), No. 1, pp. 11-.36). — Numerous experiments l)y the author indi- 

 cate that while rinderpest assumes a mild form in the camel, the disease may, never- 

 theless, be carried by such animals and they should be included in quarantine 

 regulations for the j^revention of rinderpest. 



Hog cholera, L. L. Lewis {Oklahoma Sta. Rpt. 1900, pp. 29-32). — Brief notes on 

 the causes, symptoms, and treatment of this disease. 



Swine fever, A. H. Cory {Qveensland Agr. Jonr., 7 {1900), No. ,8, pp. 279-281). — 

 The author describes the chief symptoms of various infectious swine diseases, of 

 which swine fever, swine erysipelas, and swine plague are the most important. 



Some difficulties associated with the eradication of swine fever, E. Pe.\^cey 

 {Jour. Comp. Path, ami Titer., 13 {1900), No. 3, pp. 236-2,39) .—^otes on methods for 

 diagnosing this disease and for distinguishing it from swine erysipelas and from 

 necrotic pneumonia of swine. These 3 diseases are considered by the author to be 

 the epizootic diseases of the pig. 



Second contribution to the study of the morphology of Bacillus mallei, B. 

 Allerio {Centbl. Bakt. u. Par., 1. Abt, 28 {1900), No. 12-13, pp. 353-369, figs. 26).— 

 The author describes in detail the various forms assumed by the glanders bacillus 

 when grown upon different cultural media. "White mice have been quite generally 

 stated to be refractory to glanders. Inoculation experiments by the author on 

 white, gray, and black mice resulted in the death of the white mice after 18 days 

 with numerous small glanderous tubercles. The black and gray mice did not become 

 infected. 



Hydrophobia, 0. W. Eddy {Agr. Student, 6 {1900), No. 8, pp. 158, 159).— A dis- 

 cussion of the symptoms of rabies, especially in the dog, with notes on the mortality 

 of this disease. 



The rapid diagnosis of rabies, M. P. Ravenel and D. J. McCarthy {.Tour. 

 Comp. Med. and Vet. Arch., 21 {1900), No. 7, pp. 404-406). — The authors examined 

 the spinal cord, medulla, and intervertebral ganglia in 6 cases of rabies which were 

 submitted for diagnosis. Two of the cases were dogs and 4 rabbits. The tissues 

 were sectioned for the most part without embedding, although celloidin was used in 

 some ca.ses. In all cases constant changes were noted in the intervertebral ganglia. 

 The garrglia from rabbits showed the most advanced changes. In l^oth dogs distinct 

 changes were produced in the cells of these ganglia and their capsules. The medulla 

 of all cases were examined for the rabic tubercles of Babes. These tubercles were 

 present in 5 out of 6 cases, ]mt the method is not considered so practical for raj^id 

 diagnosis as the other just described. 



Antirabies vaccination in St. Petersburg, V. Kraiouchkine {Arch. Sci. Biol. 

 [St. Petersburg], 8 {1900), No. 1, pp. 96-101).
