1018 EXPERIMENT STATION RECORD. 



Cilia and transverse divisions in the spirillum of fowls, A. Boerel ( Crnnpt. 

 Rend. Soc. Biol. [Paris], 60 {1906), No. 3, pp. 138-141, figs. 2).— In order to stain the 

 cilia of this organism it was found necessary to make use of Loffler's method. Notes 

 are given on the appearance of the cilia and on divisions which occur in the spirilla, 

 which are well illustrated. 



Preventive vaccination against distemper of dogs, aIeis {Berlin. Tierarztl. 

 Wchnschr., 1906, Xo. 3, p. 44)- — In the author's experience with Piorkowski's serum 

 in the treatment of dog distemper no beneficial results were obtained, and cases are 

 cited in which other investigators have likewise had negative results. 



Piorkowski's serum for dog distemper, Lange {Berlin. Tierarztl. Wchnschr., 

 1906, No. 4, pp. 59-61). — The author tested the value of this serum in the treatment of 

 8 cases of dog distemper. While the results obtained are not a sufficient basis for 

 general conclusions the author believes that if administered in the early stages of the 

 disease the serum gives favorable results. In chronic cases, especially such as show 

 nervous symptoms and heart weakness, the serum was of distinct benefit. The 

 author recommends the use of at least 10 cc. as a dose. 



Is rabies infectious during the incubation stage? W. Koppitz {Berlin. 

 Tierarztl. Wchnschr., 1906, Xo. 2, pp. 19, 20). — Data are presented regarding rabies in 

 animals and man, from which it appears that the disease is infectious even in the 

 incubation stage. It is therefore recommended that legal regulations should include 

 the destruction of dogs and cats which have come in contact with rabid animals 

 immediately, before the symptoms of the disease appeared in the latter. 



Transmission of rabies through superficial wounds and the value of local 

 treatment, V. Galtier {Jour. Med. Vet. et Zootech., 57 {1906), pp. 19-21). — Some 

 doubt is occasionally entertained regarding the depth of the wound necessary for 

 producing infection from rabies. The author finds that infection may take place 

 through the most superficial injuries of the skin. 



Rabies in rats, with observations on this disease in various species of 

 mice, B. Galli-Valerio {Centbl. Bakt. [etc.], 1. Alt., Orig., 40 {1905), No. 2, -pp. 

 197-204; 40 {1906), Xo. 3, pp. 318-331, figs. 2).— The possibility of rats and mice act- 

 ing as agents in the distribution of rabies has frequently been suggested by different 

 investigators. 



The author tested this matter in a number of species, including Mus rattus, M. 

 decumanus, M. musculus, and M. sylvaticus. Detailed notes are -given on the inocu- 

 lation tests made by the author and the subsequent progress of the disease. As a 

 result of these experiments it is concluded that a number of rodents may be con- 

 cerned in the transmission of rabies and that the virulence of the virus may be some- 

 what increased by these animals. The bite of small rodents may therefore become 

 very dangerous. Mus rattus was found to be well adapted as a laboratory animal for 

 the rapid preparation of virulent rabies virus. 



The relation between fowl plague and rabies, W. Rosenthal ( Centbl. Bakt. 

 [etc.], 1. Abt., Orig., 40 {1905), Xo. 2, pp. 204-206).— In the author's study of this 

 disease it was found that subdural inoculation of fowls with the virus of fowl plague 

 produced death within a short time with violent symptoms resembling rabies. It is 

 believed that some relationship exists between rabies and fowl plague. 



Prosthogonimus cuneatus in hens' eggs, K. Wolffhugel {Ztschr. Tnfections- 

 krank. u. Hyg. Haustiere, 1 {1905), Xo. 1, pp. 21-25).— -In the white of the hens' egg 

 4 specimens were found of a trematode worm belonging to the species Prosthogonimus 

 cuneatus. They were below the average in size, perhaps on account of the unusual 

 situation for these parasites. In the same egg a small amount of food material was 

 found which had become inclosed within the egg shell during the formation of the 

 egg. Attention was called to the possibility of such parasites gaining entrance to 

 hens' eggs during their formation.
