• " Whether this organism is the cause of distemper remains to be proved. 

 Out of 93 autopsies where the organism was isolated it was found In pure 

 culture uncontaminated in 71 cases. In 15 cases it was isolated from the 

 blood. In 12 cases the organism was found contaminated in the smaller 

 bronchi with the staphylococcus. In 9 cases It was found associated with 

 organisms other than the staphylococcus. In 2 cases where the organism was 

 isolated the exact bacterial findings have been lost. In a few cases I have 

 seen the organism in smears from the lungs, but was unable to isolate it or 

 grow it." 



About an epizootic goose disease, P. Loeffler {Arch. Wiss. u. Prakt. Tier- 

 heilk., 36 (1910), Sup., irp. 289-298, i)l. 1).—A description of the clinical, ana- 

 tomical, and bacteriological findings of an epizootic goose disease which 

 occurred in 1904 at Kleiu-Kiesow, near Greifswald, Germany. The bacterium 

 isolated practically simulated the one isolated by Riemer.'^ 



A transmissible avian neoplasm (sarcoma of the common fowl), P. Rous 

 (Jour. Expt. Med., 12 (1910), No. 5, pp. 696-705, pis. 3, chart i).— This paper 

 reports the first avian tumor which has been capable of transplantation to 

 other individuals. Throughout the process the sarcoma retained its character- 

 istics and was infiltrative and destructive. It resembled the typical mammalian 

 neoplasms that are transplantable. 



Bespiratory exchang-e in fowls with, g'out, G. m Gristina (Internat. Beitr. 

 Path. i(. Tlicr. Enidhrungsstor. Stoffic. u. Verdauungskrank., 1 (1909), No. 1, 

 pp. 29-47; ais. in Biochem. Centbh, 9 (1910), No. 17, p. 7//7; Chem. Ahs., k 

 (1910), No. 17, p. 2322). — When fowls were fed food rich in nuclear protein the 

 same condition of uremia and intoxication was produced as in man. Beef liver 

 produced these conditions quicker than horse meat. A depressed oxidation and 

 a lower respiration coefiicient was observed in these birds. The feeding of corn 

 did not alter the status. 



Liver disease in poultry, G. B. Morse (Rel. Poultry Jour., 17 (1910), No. 7, 

 pp. 680-682; 697-704, figs. 5). — A popular, illustrated discussion in regard to 

 the infectious, noninfectious, and doubtfully infectious liver diseases of poultry. 

 Attention is called to the crude terms often applied to the various liver diseases 

 and to the preventive measures and treatment thereof. 



A guinea pig epizootic associated with an organism of the food poisoning 

 group but probably caused by a filter-passer, G. F. Petrie and R. A. O'Brien 

 (Jour. Hyg. [Cambridge], 10 (1910), No. 2, pp. 287-305). — "An epizootic killing 

 90 per cent of a stock of 500 guinea pigs has been described ; cultures from 

 these guinea pigs frequently gave an organism indistinguishable by cultural or 

 serological tests from the Bacillus wrtryck and the B. siiipestifer. This or- 

 ganism was highly pathogenic when inoculated subcutaneonsly into guinea pigs 

 and of low pathogenicity when given to them with food. Healthy contacts put 

 with animals infected subcutaneously or fed with the bacillus did not die. 

 Sterile filtrates of organs of guinea pigs of the infected stock administered by 

 different methods frequently killed. The evidence definitely suggests that the 

 essential infecting agent in the epizootic was a filter-passer." 



Guinea pigs as chronic carriers of an organism belonging to the food 

 poisoning group, R. A. O'Brien (Jour. Hyg. [Cambridge], 10 (1910), No. 2, pp. 

 231-236). — Five of the surviving guinea pigs mentioned in the account noted 

 above, which showed definite immunity, proved to be carriers excreting the 

 bacillus intermittently 5 months later and the serum of all of them agglutinated 

 the bacillus.
