branchings and on potatoes grows as a red-brown layer, and (2) typus anthra- 

 coides wliich grows in agar and gelatin stab cultures as button-like colonies 

 and on potatoes as a dirty-gray layer. 



Anthrax precipitating sera react positively with both anthrax and pseudoan- 

 thrax bacilli, consequently the test can be regarded only as a group test. An- 

 thrax and pseudoanthrax antigens show positive by the complement fixation test 

 with pseudoanthrax and anthrax sera. On blood medium the pseudoanthrax 

 bacilli show a definite hemolysis while anthrax bacilli do not. Pseudoanthrax 

 bacilli are not pathogenic except possibly for mice. Passage tests did not 

 increase the virulence of the bacteria. 



A butcher slaughtering one of the hogs examined became infected and died, 

 having all the symptoms of anthrax. The significance of pseudoanthrax bacil- 

 lus infection in man is discussed. 



An unusual result following anthrax vaccination and a lesson, M. P. 

 Ravenel (Amer. Vet. Rev., 46 (1915), No. 6, pp. 634-638).— An account of the 

 death of 41 animals treated with anthrax vaccine. The courts decided that the 

 manufacturers of the vaccine were not at fault. 



Eradication and treatment of the foot-and-mouth disease according to my 

 system, IV, L. Hoffmann {Ileilung der Kranken unci Vertilgung der Maul und 

 Klauenseuche nach meinem System, IV. Stuttgart: Stahle <£■ Friedel, 1914, PP- 

 409-502). — A description of the author's experience in treating and eradicating 

 foot-and-mouth disease with euguform in the community of Zuoz (Graubiinden). 



Further observations on the effect of quinin in rabies, V. H. Moon (Jour. 

 Infect. Diseases, 16 (1915), No. 1, pp. 58-62). — This is a report of experiments 

 in continuation of those previously noted (E. S. R., 29, p. 883). 



It is concluded that quinin has failed to be regularly effective as a cure or 

 preventive of rabies in animals. Given in the latter stages of hydrophobia in 

 two human cases, it produced no significant results, but it appears to retard 

 somewhat the development of street rabies if given in large doses during the 

 incubation period. " The results indicate that the organism which causes 

 rabies is influenced in some degree by quinin. This is significant as showing 

 that the organism is susceptible to therapeutic measures, and gives reason to 

 hope that some drug may be found which will be of value in the treatment of 

 hydrophobia." 



Experimental study of the distribution and habitat of the tetanus bacillus, 

 W. Noble (Jour. Infect. Diseases, 16 (1915), No. 2, pp. 132-141).— " The tetanus 

 bacillus appears in the intestines of many normal animals, especially of the 

 herbivora, but apparently it seems impossible, with the methods at our dis- 

 posal, to detect it there unless it is present in relatively large numbers. Ex- 

 l>erimental evidence shows that the tetanus bacillus may multiply in the 

 intestines of such animals. The intestines, or rather the intestinal contents of 

 certain individual animals, seem to offer especially favorable conditions for the 

 growth of the tetanus bacillus ; such animals are ' tetanus carriers ' comparable, 

 in regard to the distribution of the organism, with typhoid or cholera carriers 

 among human beings. 



" The presence of tetanus spores in soils, street dust, fresh vegetables, and on 

 clothing and the skin is undoubtedly due to fecal contamination." 



Some further investigations on hog cholera, K. Uhlenhuth, H. Gildemeis- 

 TER, and K. Schern (Arb. K. Gsndhtsamt., ^7 (1914), No. 2, pp. 145-239).— A 

 continuation of investigations published in 1907, 



In the work previously reported no cognizance was taken of the fact that 

 disinfectants act less effectively in solutions, etc., containing protein substances 

 than they do in aqueous solutions. In these experiments phenol, corrosive 

 sublimate, antiformin, ozone (all used in the previous experiments), and milk
