VETERINARY MEDICINE. 787 



" We often succeeded by means of a single injection of arsenophenylglycerin 

 (1 cc. of a solution of 1:150 to 1:300) in permanently curing infected white 

 mice; also in the case of rabbits and dogs favorable results were attained with 

 the preparation. Our experiments and observations, as far as they have gone, 

 are not yet sufficiently advanced for us to give an estimate of the action of 

 the medicament in horses." 



A bibliography of 79 titles is appended to the account. 



In regard to the treatment of equine influenza, Minder {Bchiceiz. Arch. 

 Tierheilk., 52 {1910), No. 5, pp. 340-350; abs. m Ztschr. Imnnunitdtsf. u. Expt. 

 Ther., II, Ref., 3 (1910), No. 8, p. 8U)-—The author reports his results with a 

 curative serum for equine pneumonia. This serum is produced with a view of 

 having its action directed to both the pneumostreptococcus and the ovid bacte- 

 rium (Pasteurella equi). 



The results with 16 out of 17 horses were considered good. 



Etiology of canine distemper, N. S. Ferry {Jour. Infect. Diseases, 8 {1911), 

 No. Jf, pp. 399-.'i20). — "Canine distemper is foimd, as a result of this research, 

 to be an acute infectious disease primarily of the respiratory tract of the young 

 dog, caused by a micro-organism first described by me [E. S. R., 24, p. 285], to 

 which I have given the name Bacillus hroiichicanis. 



"These assertions are based on the following facts: 



"When cultures are taken early in the disease B. bronchicanis is found in 

 the respiratory tract in every case, and, if taken in the first stage, is found 

 uncontaminated. B. hroncJiicanis was isolated from 97 dogs at autopsy. In 

 68 cases it was isolated in pure culture either from the respiratory tract or 

 blood. Of 29 positive blood cultures it was found 18 times, in 13 of which it 

 was unaccompanied by any other organism. B. hronchicanis was isolated from 

 the only case attempted during life, in the very earliest stage, by means of the 

 bronchoscope. The serum from cases of distemper in all stages has given posi- 

 tive agglutination with B. bronchicanis, while the controls were invariably 

 negative. Koch's law has been fulfilled and cases of typical distemper have 

 been produced by artificial inoculation with pure cultures, the bacillus being 

 again isolated and grown in pure culture, all under conditions which have pre- 

 cluded infection from any other source." 



A list of 44 references is appended. 



In regard to the results of vaccinating with Piorkowski's serum against 

 canine distemper, Boden {Berlin. Tierdrztl. Wchnschr., 26 {1910), No. Jfl, 

 pp. 929-933). — The author details his experience with Piorkowski's serum 

 against canine distemper in 22 cases. As a result of his findings he believes 

 the serum can only be employed to advantage in acute cases, or where a slight 

 catarrh of the respiratory channels and the conjunctiva exists, and where a 

 high initial fever exists or has existed. 



Prophylaxis against echinococcus disease, P. Bababaschi {Oaz. Osped. e 

 Clin. [Milan^. 31 {1910), No. 116, pp. 1225-1227; abs. in Zentbl. Gesam. Physiol. 

 H. Path. Stojfivechsels, n. ser., 6 {1911), No. 5, p. 202).— The author injected 

 increasing amounts of sterile echinococcus cystic fluid (from 3 to 60 cc.) into 

 dogs, and later on gave them 400 living echinococcus heads. The dogs did not 

 become sick, and after a period of 21 months no parasite could be detected in 

 the intestinal tract. As immunity against the disease can be conferred upon 

 the young through the placenta, the author recommends the obligatory immuniza- 

 tion of female dogs against the disease. 



A new species of cestode parasite (Tsenia balaniceps) of the dog and of the 

 lynx, with a note on Proteocephalus punlcus, M. C. Hall (Proc. U. S. Nat. 

 Mils., 30 {1911), pp. 130-151, figs. 9). — The species here described as new was 

 taken from a dog from Fallen, Nev., and from a lynx {Lynx rufus maculatus) 

 from southern New Mexico.
