It will be noticed that all of the seeds in the smallest lot 
are lighter than water. This observation applies to grape seeds 
in general. In the next larger size there are relatively a large 
number of floaters. Only the seeds of highest specific gravity 
germinated. In the case of the variety (Mabel) shown in this 
table the percentage of germination among the small seeds was 
less than what it commonly is with such vigorous and self-fertile 
varieties as Concord. It is noticed from the table also that as the 
size of the seed increases the number of light seed decreases; but 
‘at the same time the maximum range of the heavier seed becomes 
less and less. This observation also is of general application. 
In the seeds of largest diameter there are very few light seeds. 
In the table the range within which germination took place is 
included within the irregular line. 
These facts as to the distribution of seeds of different sizes 
through the range of specific gravity are shown in graphic form in 
Chart II. A glance at this chart shows immediately that the 
great mass of seeds are of medium size, which would have been 
anticipated. The small seeds are numerically greater in number 
than the large ones, but fewer of them fall within the range of 
germinable seeds. On the other hand almost all of the large 
seeds are seen to be of good quality. The medium sized seeds 
are seen to fall in larger part within the range of good seed.
