By comparison with the extremes for green stalks it is seen that the 

 albuminoids are higher in the dry substance of one of the ensilages, No. 

 1502, than in the dry substance of any of the stalks. The high figure 

 in the ensilage is probably only relative, clue to great loss of carbby- 

 drates, and little change of albuminoids. Exact quantitative experi- 

 ments are greatly to be desired, in order that we may have some expla- 

 nation of the interesting changes which are shown by what has been 

 already done.
