Report op the Assistant Chemist of the 
The great variation shown in the dry substance, also in the water 
content, for the two years, leads us to carry further our investigation, 
to learn whether any other differences could be found.

Unfortunately, the sugars and starch were not determined in the 
grasses for 188G ; so we are unable to compare the differences in the 
nitrogen free extract for the two years.
