678 EXPEEIMENT STATION RECORD. 



in injecting a 2 per cent solution of carbolic acid into the affected parts of the 

 udder. The immediate result of repeated injections of this sort was to check 

 the progress of the disease and apparently to destroy the micro-organism, but 

 The tissue of the udder sloughed off as a result of the previous infection and 

 treatment. This method may be of value in preventing the spread of the infec- 

 tion, but in curing the disease the author recommends the surgical method of 

 the removal of all affected tissue. 



A disease of the pig due to Spirocheeta, S. Dodd (Join: Compar. Path, and 

 Ther., 19 (1!)0G), No. 3, -pp- 216-222. ])L 1, pf/. 1). — Several species of this genus 

 are known to be pathogenic for animals, but the one observed by the author 

 was not found in the blood circulation but in skin lesions over the surface of 

 the body. A post-mortem examination of affected pigs showed almost no char- 

 acteristic pathological conditions outside of the skin lesions except anemia. 

 Inoculation experiments with the blood of affected hogs showed that the para- 

 site was not present in the blood. It was found that the disease was readily 

 transmitted by contact. 



Pseudoleukemia in pigs, Rottke {Berlin. Tierdrztt. Wchnschr., 1906, No. 

 ,W, pp. 712, 713). — In cases of this disease the bronchial and mediastinal glands 

 ai-e greatly swollen and all of the lymphatic glands show a yellowish-white color. 

 The nuisculatnre appears jiale and the liver and spleen are somewhat enlarged. 

 The author believes that some cases of pseudoleukemia will prove to be of a 

 tuberculous nature. 



Rachitis accompanied with spasms in pigs, Fromberg ( Moaned skr. Dyr- 

 Utffcr, IS (1906), .\o. 6, p. 255). — In treating cases of rachitis in pigs complicated 

 with symptoms of cramps, the author obtained satisfactory results from pump- 

 ing air directly into the abdominal cavity by means of the ordinary apparatus to 

 be used in the treatment of milk fever. The abdominal cavity was distended by 

 pumping in air for a period of 7 to 20 minutes. 



Susceptibility of ruminants and apes to the trypanosome of dourine, F. 

 Mesnil and J. Rouget (Ann. Inst. Pasteur, 20 (1906), No. 9, pp. 689-697).— It 

 has generally been considered that ruminants and apes are not susceptible to 

 dourine. In order to test this matter the authors undertook a number of inoc- 

 ulation experiments in which it appeared that cattle, goats, and apes may be 

 infected with the trypanosome of dourine in the same manner as with other 

 trypanosomes which are pathogenic for mammals. 



The diagnosis of rabies, Forgeot and Nicolas (Ann. Soc. Agr. ScL et Indus. 

 Lyon, 1905, pp. 390-J,0Jt, pjs. S). — The anatomical changes in the nervous system 

 in cases of rabies are described with particular reference to Negri's corpuscles, 

 which bodies were carefully studied by the authors. 



The conclusion is reached that when Negri's corpuscles are found in Amnion's 

 horn a positive diagnosis of rabies can be safely announced. The authors were 

 unable to find Negri's corpuscles except in actual cases of rabies. This method 

 of diagnosis suffers from certain disadvantages since the detection of Negri's 

 corpuscles is a rather difficult one, and the process occupies considerable time 

 and necessitates many complicated histological manipulations and the use of a 

 high magnification. The results obtained in most instances, however, are suffi- 

 cient recompense for the time employed. 



The elevation of the body temperature through the treatment of rabies 

 and infectious diseases, P. Remlinger (Compt. Rend. Soc. Biol [Paris], 60 

 (1906), No. 22, pp. 1030, 1031). — Rabies virus is well knovs^n as being very sus- 

 ceptible to the action of heat. The author suggests that this fact may be nat- 

 urally connected with the rarity of rabies in birds on account of their high 

 normal temperature and the infretpiency of disease in the Tropics.
