ported to the National Bison Range at Ravalli, Mont., and the Wichita Game 

 Preserve in Oklahoma. 



The establishment of a winter refuge, where the feed can be preserved by 

 excluding stock during the summer, is essential for the proper protection of 

 the elk, and is recommended. 



The deer of Chantilly forest decimated by helminths, E. Bbumpt {Compt. 

 Rend. Acad. Sci. [Paris], 152 (.1911), No. 13, pp. 906-909; abs. in Jour. Roy. 

 Micros. Soc. [London], 1911, No. 6, p. 760). — For 4 or 5 years deer living in 

 the forest about Chantilly have suffered from a disease, marked by cachexia, 

 which has resulted fatally to a large number, a score or more of fawns of 10 or 

 11 months of age dying during the single month of February, 1911. In exami- 

 nations to determine the infestation of 26 deer, the author found 23 to be in- 

 fested by Dictyocaulus nosrneri, 11 by CEsophagostomum venulosum, 2 by D. 

 fllaria, 8 by Capillaria n. sp., 4 by Strongle sp.?, 8 by Nematodirus roscidus, 

 and 3 by Trichocephalus affinis. In 3 deer on which post-mortem examinations 

 were made, death was found to have been due to pulmonary strongylosis, com- 

 plicated in 2 cases by intestinal helminthiasis. 



The cultivation of an acid-fast bacillus from a rat suffering with rat 

 leprosy, H. T. Hollmann (PuT). Health a)id Mar. Hosp. Sere. U. ,s'., PuJ). Health 

 Rpts., 21 (1912), No. 3, pp. 69, 70).— In this preliminary report the author 

 records having " succeeded in cultivating in pure culture an acid-fast bacillus 

 from a rat suffering with rat leprosy by the method described by Clegg "■ in the 

 cultivation of the human lepra bacillus. Of the 8 rats inoculated with the 

 pure culture subcutaneously acid-fast bacilli were found in all, in the lesion 

 of the skin of 8. in the lungs of 2, and in the nasal discharge of 1. Of the 

 3 rats inoculated intraperitoneally no lesions of the skin nor of the Internal 

 organs were found, but the splenic pulp in 2 of them contained acid-fast 

 bacilli." 



A microfilaria (Microfilaria rosenaui n. sp.) from the California ground 

 squirrel (Citellus beecheyi), G. W. McCoy (Parasitology, // (1911), No. 3, pp. 

 220, 221, pi. 1). — The nematode here described as new to science has been found 

 in squirrels coming from all parts of California east of the Sierra Nevada 

 Mountains, and between the Mexican border and the Sacramento River. " Ro- 

 dents from the southern sections of the State seem to show a higher percentage 

 of infestation than those from farther north. It is probable that at least 5 per 

 cent of the squirrels from the part of the State in which the parasites are found 

 harbor the worm. There is no evidence that the nematode exercises any dele- 

 terious influence on the host. The adult forms of the parasite have not been 

 found though careful search for them has been made." 



The tarbagan (Arctomys bobac) and plague, P. Preble (Pui. Health and 

 Mar. Hosp. Serv. U. 8., Pub. Health Rpts., 27 (1912), No. 2, pp. 31-39).— T^e 

 author summarizes evidence from which he concludes, a priori, that the tarbagan, 

 a marmot common in Siberia and Mongolia, may perform a role similar to that 

 of ground squirrels in the transmission of plague. " This has, however, only 

 the Aalue of an hypothesis since bacteriological and pathological proofs are as 

 yet lacking." 



A bibliography of 24 titles is appended.
