is lai-gely thrown out of tlie blood by subjection to vigorous centrifugalizatiou. 

 After this treatment the virus is found associated with the corpuscular elements 

 of the blood. The virus of fowl plague obtained from the brain is not destroyed 

 by saponin during an exposure of ] hour. Apparently the virus has the power 

 (>f passing through the finest filters. In most cases, minute corpuscles were to 

 be observed which may be the organism of the disease. 



Coli-septiceniia in fowls as a disease which occurs during transportation, 

 L. CLAtssEN {Ubcr KoUbaktcficnscptih-diiiic hci Hiilincrn aJs Trans poftkrank- 

 heit. Inauff. Diss. Univ. Bern, 1907, pp. SO, pi. 1). — The coil bacteria which are 

 frequently found in the intestines of healtliy fowls may become so modified by 

 unfavorable conditions which occur during transportation as to produce a seri- 

 ous form of septicemia. The virulence of these organisms may be artificially 

 increased by several inoculations of canary birds. The mortality from this 

 form of septicemia is not greater than 50 per cent. The disease may be trans- 

 mitted by inoculation or by feeding, and the incubation period is about 12 

 hours. 



Infectious inflammation of the air sacs in geese, G. Bugge {Ztschr. Infek- 

 tionskrank. u. Hi/g. Haiistierr, J (]QOS), Xn. 5, pp. JflO-J/SO, fig. 1). — An outbreak 

 of an apparently new disease among geese was observed by the author and a 

 study was made of the origin and etiology of the disease. It was apparently 

 introduced with geese imported from Russia. Affected bii'ds show a condition of 

 emaciation. The air sacs, particularly those in the body cavity, are of a yellow- 

 ish color and upon the inner surface whitish yellow masses of exudative origin 

 are to be observed. Similar conditions are noted upon the serous covering of 

 the liver, spleen, intestines, and kidneys. In some cases the outer covering of 

 the stomach is likewise affected. In the blood of diseased birds, bacteria were 

 found and i)ure cultures were made. The organism in question produces no 

 effect in hens when injected into them and this test may be used as a means of 

 arriving at a differential diagnosis between fowl cholera and infectious inflam 

 matlou of the air sacs. The latter disease appears to be confined strictly to 

 geese, as ducks and jngeons, as well as common fowls, proved to be refractory. 

 No satisfactory method of treatment or prevention has been devised. 



The penetration of toxins from parasitic worms into the body of the host, 

 Weinherc; K'oiiijit. Rend. .S'or. Bioi. [I'aris]. 6', (190S). Xo. 1, pp. ;^J-27 ) .—Ac- 

 cording to the author sclerostomum, esophagostomum, and other parasites may 

 secrete substances which become absorbed by the host and constitute a part of 

 the toxic symptoms observed in cases of infestation by the parasites in question. 



Feeding stuffs poisonous or injurious for animals, R. Dumont (Prog. Agr. 

 ct Tit. {Ed. 1'Est), 28 (1901). Nos. .',8, pp. 658-661: 50, pp. 722-726; 51, pp. 756- 

 760; 52, pp. 778-781). — Attention is given to a brief consideration of species of 

 Euphorbia, wild mustard, and various other wild plants, including rhododen- 

 dron, aco!iite, and digitalis which have been found to be poisonous to stock. 

 ileution is made of the poisonous effects sometimes produced by cultivated plants 

 such as sorghum, lupines, potatoes, tobacco, and various species of beans. The 

 author also discusses briefly the unfavorable results which may follow the use of 

 cotton-seed meal, fern'euted molasses, and other commercial feeding stufts. 



The effect of digitalis and its glucosids upon various ruminants, A. Salvis- 

 BERd (I'chrr die ivirkung von digitaiis und digifaiisglijkosidcn aiif den orgnnis- 

 miis rerschiedener iriederkauer. Inaiig. Diss. TJniv. Bern, 1907, pp. .'(6). — The 

 author's experiments were carried out on sheep, goats, and cattle. In these 

 exiieriiHonts it was found that the leaves of digitalis could be given to ruminants 

 without producing any apparent effect. Cows received doses which would be 

 fatal for horses without giving any reaction whateA'er. The conclusion is
