This table emphasizes the need of having seeds in the air dry 
condition when specific gravity determinations are to be made. 
It shows also that the method of specific gravity is less applicable 
to seeds which must be kept moist in order for them to germi- 
nate. Among such are apple seeds and various other seeds which 
it is customary to stratify in the fall. At the same time these 
observations show that the specific gravity of the fresh seeds 
follows in a general way, though irregularly, the specific gravity 
of the air dry seed.
