Removal of the tonsils and adenoid tissue resulted in the prompt 

 disappearance of the organisms upon culture. — G. H. S. 



A Study of the Etiology of Chronic Nephritis. P. K. Brown and W. T. 



Cummins. Journ. A. M. A., 1916, 66, 793-797. 



From the study of a large number of cases of nephritis the authors 

 conclude that venereal and other serious infections, chiefly strepto- 

 coccus and pneumococcus, have a very definite bearing on the occurrence 

 of advanced kidney disease. — G. H. S. 



Experiynental Syphilis in the Rabbit Produced by the Brain Substance of 

 the Living Paretic. Udo J. Wile. Jour. Exp. Med., 1916, S3, 

 199-202. 



Brain tissue from living paretics easily produces experimental syphilis 

 in rabbits and the spirochaetes contained in this living tissue consti- 

 tute a virulent strain with a shorter period of incubation for the rabbit 

 than exists with other strains. — B. W. 



The Incidence of Syphilis Among Juvenile Delinquents. Thomas H. 



Harris. Journ. A. M. A., 1916, 66, 102. 



Wassermann tests performed on the sera of 365 juvenile delinquents 

 taken without selection, gave positive results in about one-fifth of the 

 cases. The author regards much of the infection as acquired rather 

 than congenital. The relation of syphilitic infection to mental status 

 is discussed. — G. H. S. 



Cultural Experinfients with the Spirochaeta pallida Derived from the 

 Paretic Brain. Udo J. Wile and Paul Henry De Kjriuf. Jour. 

 A. M. A., 1916, 66, 646. 



Rabbit inoculation with paretic brain has yielded pure cultures of 

 pallida. The strains may be cultivated in artificial media. The or- 

 ganisms from brain tissue are morphologically identical with spiro- 

 chaetes derived from cutaneous syphilids, although the growth of the 

 latter is much more luxuriant. — G. H. S. 



Diphtheria Carriers. J. C. Geiger Frank L. Kelly, and Violet M. 



Bathgate. Jour. A. M. A., 191b, 66, 645. 



Nose and throat cultures were taken from all contacts in six inves- 

 tigations. Nose cultures gave 42.2 in the percentage average of posi- 

 tives, throat cultures 7.9. Of all positive cultures 72 per cent were 

 nose and 28 per cent throat. 



The Schick test applied in one investigation proved of value in dis- 

 tinguishing between contacts and carriers. — G. H. S. 



Rdle of the Lymphatics in Ascending Renal Infection. Daniel N. 



Eisendrath and Jacob V. Kahn. Jour. A. M. A., 1916, 66, 561. 



In a series of experiments on dogs and rabbits the authors have 

 demonstrated that infection of the bladder with the Bacillus coli,
