Table III. — Shotving Increase in Germination of Seeds by 



Separation. 



In some previous separations with onion seed, in which. 7 

 samples of seed were used and an average of 14 per cent, blown 

 out, we obtained an increase of 9 per cent, in the germination. 



In Table IV. are shown the results of seed germination before 

 separating, also the germination of the heavy and light seed. 

 The average amount of seed discarded here was 8 per cent. The 

 heavy seed showed an average increase of 5 per cent, in the ger- 

 mination, while the light or discarded seed gave an average of 

 only 57 f)er cent., or 28 per cent, less than the heavy seed. 



Table IV. — Showing Increase in Germination of Seeds by 



Separation. 



In Table V. the per cent, of germination and the weight of 

 celery seedlings are shown, the results being an average of two 

 experiments. The amount discarded in this experiment was 15
