18. Corn ripe. The amount of water in the stalks, 
leaves and sheaths, has gradually decreased 
since the 13th of September. The kernels 
have gradually increased in specific gravity 
since their first appearance.

Specific gravity of kernels taken directly from 
the plant, 1" 233378. 
Specific gravity of kernels after being deprived 
of water, 1-2753. 
Depriving the kernels of water, in this case, 
has increased their specific gravity.
