sulphur was regulated directly by the extent of the total nitrogen and 

 sulphur elimination. This point is well illustrated in the following 

 table which contains data regarding the so-called "partition" or 

 "distribution" of the urinary nitrogen and sulphur. 



THE NITROGEN AND SULPHUR "PARTITIONS" AS INFLUENCED BY DIET 1 



It will be observed from an examination of this table that a normal 

 protein diet which gave 16.8 grams of urinary nitrogen yielded 87.5 

 per cent of this nitrogen as urea, 3 per cent as ammonia, 3.6 per cent as 

 creatinine and i.i per cent as uric acid; whereas a "non-protein diet" 

 (starch and cream containing about i gram of nitrogen) which gave 

 only 3.6 grams of urinary nitrogen yielded only 61.7 per cent of this 

 nitrogen as urea but gave a greatly increased percentage output in the 

 case of each of the other nitrogenous constituents mentioned, e.g., 11.3 

 per cent as ammonia, 17.2 per cent as creatinine and 2.5 per cent as 

 uric acid. The percentage output of neutral sulphur was also greatly 

 increased. 



It will furthermore be observed that the actual daily output of
