The urinary nitrogen likewise showed a considerable diminu- 

 tion when 50 per cent, alcohol was administered. The total nitro- 

 gen decreased 12 per cent. When the quantity of alcohol was 

 increased, however, the nitrogen failed to undergo a corresponding 

 diminution — our analysis showed a decrease of only about 4.4 

 per cent, as compared with the control period. The average 

 daily output of nitrogen remained practically the same during the 

 10 days of the after period. We have also made determinations of 

 the urinary chlorides. The influence of alcohol was plainly evi- 

 dent and was similar to that on the other urinary constituents. 

 The chlorides decreased 17-22 per cent, but they practically re- 

 turned to normal in the after period which was continued for 

 10 days. 



As was mentioned before, these particular results were obtained 

 in the analysis of the urine of one dog. Whether alcohol behaves 

 the same in other individuals remains to be seen. There are some 

 indications, however, that not all dogs react alike to alcohol.

Spirochaeta microgyrata (Low) and mouse tumors. 

 By GARY N. CALKINS. 



[From the Department of Zoology, Columbia University, .] 

 A black female mouse purchased from a breeder in New York 

 City and belonging to a set of from 200 to 300 mice under obser- 

 vation by Mr. Horton of Columbia, in experiments on Mendelian 

 inheritance, developed a tumor on the right fore leg. The shoulder 

 and axilla were involved and the mouse could not use the leg in
