45. Biochemical reasons why free purgation is necessary in 

 combating acidosis of diabetes; results of clinico-chemical ob- 

 servations. Allan C. Eustis. (Laboratory of Clinical Medicine, 

 Medical Department, Tulane University, New Orleans, La.) Ob- 

 servations were made upon twelve patients in the von Noorden 

 clinic in Vienna and lipon four patients in the private practice of 

 the writer during the past year. Tests for indican were made by 

 Salkowski's method, the same amount of urine being used for each 

 test, and the grade of the color imparted by the indigo was recorded 

 +, ++, + + +J etc. The ammonia determinations were made 

 according to Folin's method. In each case there was a marked 

 degree of acetonuria, also a large percentage of ammonia nitrogen 

 in the urine, and a high indican index.
