it is recommended that there be inoculated from the original fecal sus- 

 pension 0.1 cc. into 1 per cent glucose extract broth containing 1 : 300,000 

 of the brilliant green. If slight growth develops on the green plates, Endo 

 agar is inoculated from the broth tubes after 18 hours. In tests made 

 upon carrier and normal stools, and of convalescents prior to discharge it 

 was found that many fecal types were restrained while the typhoid bacilli 

 developed well. In one instance the positive results were increased 36 

 per cent over Endo plates. The method also proved successful for the 

 isolation of members of the paratyphoid-enteritidis group from feces. —

MEDICAL BACTERIOLOGY 



The Effect of Continuous Electric Light in Experimental Arthritis. W. E. 



SiMMONDS AND J. L. MooRE. Arch. Int. Med. 1916, 17, 78-81. 



Exposure to continuous incandescent electric light prevented or ren- 

 dered less severe experimental streptococcal arthritis in rabbits. When 

 the light treatment was begun after the development of arthritis, treated 

 animals improved, while control animals continued to develop new 

 lesions. — G. H. R. 



Lesions Produced in Rabbits bij Repeated Intravenous Injections of Living 

 Colon Bacilli. C. H. Bailey. Proc. Soc. Exp. Biol, and Med., 1915, 

 13, 62-63. ... 



Colon bacilli were injected intravenously into rabbits at 3-4 day inter- 

 vals over long periods. Animals surviving 88 to 142 days showed fibrous 

 and hyaline changes in the kidneys, spleen and liver. In the spleen a 

 material resembling amyloid was formed about the Malpighian bodies 

 but the amyloid nature of this substance was not conclusively demon- 

 strated.— W. J. M. 



Tuberculosis in Infancy. C. H. Dunn, Amer. Jour. Diseases of Children, 



1916, 11, 85-94. 



The author briefly reviews the various opinions that have been held 

 concerning the portal of entry and the type of the organism in tuberculo- 

 sis of children. The observations recorded consist of twenty-five 

 autopsies upon infants under two years of age. The examinations were 

 particularly directed toward the lungs and intestines, which were cut 

 into small pieces and all suspicious portions sectioned and examined 

 microscopically. In twenty-two of the twenty-five cases there was 

 found what was regarded as the primary focus and portal of entry. The 

 author therefore, disagrees with the opinion that the tubercle bacillus 

 may in many cases enter the body and leave no local histological evidence. 

 In twenty of the cases the supposed primary was located in the lung and 

 in two it was found in the intestine. In only five cases were animal 

 inoculations made and the type of organism studied. Four of these 

 proved to be human and one bovine. The one bovine culture came 

 irom one of the cases in which the primary lesion was located in the 

 intestine.— R. M. T.
