According to these results, the proportion of nitrogenous sub¬ 
stances in the crops, both in grain and straw were influenced 
by the manures to a remarkable degree. The richest in 
nitrogen are the products of the unmanured and of those plots 
which did not receive any phosphatic food ; we find in these 
10 Inch the chaff, which contained according to the analysis of a mixed 
sample 11.69% moisture, 0.5186°/ 0 nitrogen, 0.729370 phosphoric acid, 
°-533°/o potash and o.o8667 0 lime.
