METABOLISM IN NEPHRITIS 369 



When this test was first conceived by Hedinger and Schlayer, it was 

 supposed that a full dietary containing a reasonable amount of fluids, salt 

 and purins was necessary to obtain a "Normal response" on the part of 

 the kidney. Accordingly they designed an elaborate series of meals. 

 Mosenthal(&) (1915) modified their procedure to meet American standards 

 of three meals a day ; the outline giving directions for the diet and collec- 

 tions of urinary specimens at the time were the following:
