decided on glucose, one part of glucose to three of water, Sp. Gr. 1.21. In 
this mixture the light kernels came to the top. I thus had light and heavy 
kernels, and with these I experimented as follows: 
First Test.—3800 kernels were taken from every other row of an ear 
that tested “good” in the usual “seed box” germinating test: Lot 1, 800 
kernels from the alternating rows were divided into two lots by the specific 
gravity test; lot 2 showed 258 heavy grains; lot 3, 42 light grains. (Lot 
1 was not put in solution.) The vitality of these three lots was deter- 
mined by testing in a box, under identical conditions.

Second Test.—100 kernels were taken from an ear which showed a 
germinating test of 4 dead kernels and 1 weak out of 5 (the usual test 
number being 5). These kernels were separated by the specific gravity 
test and tested as before.

Third Test.—100 kernels were taken from two ears which showed 
; 
“extra strong” in the germinating test. They were separated by the specific 
gravity test, which gave a high percentage of heavy kernels, and were 
tested under conditions similar to the above. (It will be noticed that the 
per cent of light kernels is quite small and that all germinated. )

Fourth Test.—Two full rows were taken from 25 ears, in which all 
ofthe five test kernels bad failed to germinate in the “box test.” This 
gave a total of 2,116 kernels. The specific gravity test showed 592 heavy 
and 1,524 light; these were tested as mentioned above.
