690 EXPESIMENT STATION RECORD. [Vol. 37 



Milk sickness, D. T. Gray {North Carolina Sta. Rpt. 1916, p. S6). — A brief 

 statement of work by Curtis and Wolf (E. S. K.. 37. p. 583 >. 



Studies on the paratyphoid-enteritidis group. — III, Some oiltural charac- 

 teristics and their relation to host origin, C. Krumwiede, jr., Josephine S. 

 Pbatt, and L. A. Kohn {Jour. Med. Research. 35 {1911), No. S, pp. S57S66). — 

 "The quantitative differences in the reduction of fuchsin, added to the fer- 

 mentative results, especially of dulcit and arabinose, give fairly defined groups. 

 This grouping is only suggestive in that it correlates to some extent with host 

 origin, a correlation hitherto not observed. It also correlates with the primary 

 or secondary invasive properties of the various types. As would be expected, 

 the latter are much more heterogeneous. 



" Some of the re-sults do uot correlate with agglutinative results and suggest 

 the nece.ssity of further study in relation to such correlation." 



Studies on the paratyphoid-enteritidis group. — IV. The differentiation of 

 the members of the paratyphoid-enteritidis group from B. typhosus with 

 special reference to anaerogenic strains and observations on the fermentative 

 characteristics of the avian types, C. Kkvmwiede, ju.. and L. A. Kohn {Jour. 

 Med. Research, .36 (1911), No. S. pp. 509-51S). — "The ability to produce acid 

 from rhamnose is the essential characteristic of the paratyphoid-enteritidis 

 group, differentiating both the aerogenic and anaerogenic members from 

 /?. typhosus. Additional cultural differences between B. typhosus, B. sanguina- 

 rium, and B. pnllorum are presenteil. The agglutinative relationship of the 

 strains studied is recorde<l. Observations are added on the low or latent 

 avidity for carbohydrates In relation to variability and practical differentia- 

 tion. Without due regard to the.se factors, erroneous differential significance 

 night easily be given to variation even among members of the fixed groups." 



Effect of the injection of nonspecific foreign substances on the course of 

 experimental rabies, W. H. Bubmlihter (Jour. Inject. Diseases, 21 (1911), No. 

 1, pp. 95-101). — "The injection of certain nonspecific substances (hor.se serum, 

 serum globulin, egg white, egg yolk, broth, typhoid vaccine, or tuberculin) does 

 not inhibit the course of experimental rabies in rabbits produced by nonat- 

 tenuated virus. The seemingly beneficial effect of tuberculin in the early 

 .series of the experiments must be disregardetl because of the survival of some 

 control animals inoculated at a later date with the same virus. . . . Rabbits 

 surviving an intracerebral inoculation of attenuated rabies virus (fixed or 

 street virus) may become hypersensitive to a reinoculation of the same virus 

 made in the same way." 



Tuberculosis in camels, F. E. ^Iason (Jour. Compar. Path, and Ther., SO 

 {1917), No. 1, pp. SO-Sff). — The literature on the occurrence of tuberculosis in 

 camels is briofly reviewed. C-ontinuing the work previously noted (E. S. R.. 

 29, p. 676). the author has examined and made bacteriological studies of a large 

 number of camels slaughtered in the Cairo abattoir. The disease appears to 

 occur chiefly in Egyptian camels and the causative organism to be of the bovine 

 type. 



The source, method of infection, course, distribution of lesions, and histology 

 of lesions of tuberculosis in the camel are briefly discussed. 



The subcutaneous tuberculin test with ordinary tuberculin was successfully 

 employed on infected animals. Data relative to the variations in the normal 

 temperature of camels are submitted. 



Brisket disease, G. H. Glo\t;r and I. E. Newsom {Colorado Sta. Bui. 229 

 {1911), pp. S-8. figs. S). — This is a revised and abbreviated edition of Bulletin 

 204. previously noted (E. S. R.. 32. p. 7S1). 



Report of the- division of veterinary science, G. A. Roberts {North Carolina 

 Sta. Rpt. 1916, pp. 55-51). — The principal work of the year was with conta-
