This table conclusively shows (i) that the proportion of 
nitrogenous compounds in the grain depends, within certain 
limits, on the supply of nitrogen in the manure, and (2) that 
barley poor in crude protein contains more mealy grains than 
when it is rich in nitrogenous components,—Similar observa¬ 
tions were made before the above researches by Millon, 
W. Schuhmacher, Th. Siegert, A. Nowacki, and recently 
also by Th. Dietrich. 
To resume our subject, the crucial test for ascertaining 
whether the fact revealed by our researches is actually connect¬ 
ed with an insufficient resistibility to pressure or dynamical 
forces, was now plain before us : We had to decide whether 
rice grains poor in protein break under a less pressure than 
those rich in protein. For this purpose we used a very simple 
instrument, viz. a graduated lever fixed on one end and lying 
horizontally on a block on which an unhurt hulled rice grain
