Lot I received rather more dry matter than Lot II, and made 
slightly better gain. Lot I received 131 pounds, or 1.2 pounds 
per day more albuminoids than did Lot II. On the other hand 
Lot IL consumed just 131 pounds more nitrogen-free extract 
than did Lot I. Itis plain then that in this particular trial we 
can trace no apparent increased value for the substitution of 
albuminoids for nitrogen-free extract. We must then look for any 
differences in the amount digested, and for this purpose the 
digestion experiments were carried out with these same animals. 
- Before considering these trials we give, calculated from the food 
consumed and the average digestion coefficients, the amounts of
