monia and urea determinations were made without delay, so 

 as to avoid error through decomposition of the urine. The 

 results are given in terms of the radicles as found by the 

 analyses :

The urines numbered i, 2 and 3 were from well-nourished 

 male students; numbers 4, 5 and 6 from men who had been 

 for a long period consistent vegetarians, consuming only 

 bread, fruits, vegetables and nuts and a very small amount of 

 milk. The average volume for i, 2 and 3 was nearly 1,200 

 cc., for 4, 5 and 6 about 1,000 cc. No characteristic differ- 

 ences are readily apparent. In the above table no determina- 

 tions of the traces of xanthine bodies are included and there 

 are also no carbonic acid determinations. For comparison be- 

 tween the bases and acids it is convenient to calculate the first 

 in terms of Na and the latter in terms of Cl, assuming that 

 the acids all act to form theoretically neutral salts. The re- 

 sults of such a calculation are given in the table below.
