DISCUSSION OF RESULTS. 
The data furnished by this experiment appear to justify the fol- 
lowing statements: 
1. The comparative nutritive value of the rations——The quantity 
of digestible dry matter fed daily varied in the several periods from

phosphorus periods being not greatly unlike what was eaten in the 
two low phosphorus periods. The quantities of digestible protein 
consumed in the several periods varied from 1.8 pounds daily to 2.8
