As will be seen by the figures in the table, the metabolic nitrogen 
is equal to the total nitrogen in the untreated feces less the amount 
remaining in the feces after treatment with the reagents: that is. it is 
equivalent to the amount dissolved out by the reagents. In a previous 
experiment'' it was found that the solvents above mentioned dissolved 
4*2 per cent of the total nitrogen present.
