alimentary canal, but intravesicular inoculation was more successful. 

 The duration of infection in all cases was limited but appeared sufficient 

 for therapeutic measures. — P. B. H. 



The Localization of Streptococci in the Eye. E. E. Irons, E. V. L. 



Brown and W. H. Nadler. Jour. Infect. Diseases, 1916, 18, 315. 



A study of the invasive action of haemolytic streptococci from a 

 case of iridocycHtis. Inoculated into rabbits the cultures produced 

 iritis for 17 days after isolation, but showed a loss of the quality of 

 localization. This could not be regained when once lost. The au- 

 thors conclude that "the invasive power of an organism for special 

 tissue may change within a short period of time during residence in the 

 original host, during animal passage, and in culture, without pronounced 

 or constant changes in cultural characteristics, or in general virulence 

 for animals." — P. B. H. 



Chronic Influenza in Pulmonary Tuberculosis. M. L. Hamblet and 

 H. L. Barnes. Archives Int. Med., 1916, 18, 313-316. 

 The purpose of the author's investigation was to determine the 

 number of tuberculous patients infected with influenza bacilli and to 

 determine whether the symptoms of patients diagnosed as having pul- 

 monary tuberculosis could be caused by a chronic influenza infection. 

 Examination for influenza bacilli was accomplished by cultural and 

 microscopic methods. Ninety-three to 96 per cent of patients diag- 

 nosed as having both open and closed tuberculosis appeared not to 

 harbor influenza bacilli. The sputum of twenty patients in whom 

 the diagnosis of tuberculosis was doubtful was negative for influenza 

 bacilH.— G. H. R. 



The Examination of the Urine and Feces of Suspect Typhoid Carriers 

 with a Report on Elaterin Catharsis. F. 0. Tonney, F. C. Cald- 

 well AND P. J. Griffin. Jour. Infect. Diseases, 1916, 18, 239-246. 

 The writers report the following results of the examination of 290 

 specimens of urine and 298 specimens of feces : The use of elaterin ca- 

 tharsis is of assistance in detection of typhoid bacteria, and at the same 

 time raises the value of a negative test. Endo plates were found 

 most satisfactory. Lactose-peptone-bile was found to inhibit typhoid 

 growth. The infectivity of typhoid carriers, in the absence of diarrhea 

 is probably negligible. Typhoid bacteria were not found in the urine 

 after administration of hexamethylenamin. — P. B. H. 



A Contrihutioti to the Chemotherapy of Tuberculosis, First Experimental 

 Report. G. Koga. Jour. Exp. Med., 1916, 24, 107-147. 

 Inspired by Koch's observation on the remarkable germicidal action 

 of potassium auricyanide on the tubercle bacillus in vitro, Koga pre- 

 pared a compound of copper and cyanide (details unfortunately not 

 given) and studied its action on experimental tuberculosis in the guinea
