OF NUTRITION. 



deducting the urea and salts from the total residue there remained for other 

 urinary constituents 28 grammes, which further analysis showed to contain 

 ' 9.6 grammes of carbon, 2.5 grammes of hydrogen, and 15.9 of oxygen. 40.7 

 grammes of moist fbeces, which when dried weighed 11.2 grammes, contained 

 4.9 grammes of carbon, 0.7 of hydrogen, 07 of nitrogen, 1.5 of oxygen, aud 

 3.4 grammes of salts. We have thus in the Egesta
