A brief analysis of the above table shows that in 15 of the 19 

 experiments from 12.00 to 27.45 per cent, or an average of 

 17.87 per cent, of the fecal nitrogen was soluble in ether, 

 alcholiol and hot water, in the same cases additional treat- 

 ment witli cold lime water taking out an average of eight per 

 cent, more, the amounts extracted Viy this latter solvent ranyfing in 

 the several experiments from 2 46 to 15.66 per cent, of the toIa^ 

 nitrogen. 



The percentage of nitrogen, dissolved by the pepsin digestion was 

 on the average 12 per cent, more than that extracted by the com- 

 bined action of the other four solvents.
