Tim. OBSEKVATIOirs, PARTS AND PROPORTtONS. QUANTITIES, 



October 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. 

 Relation of the difTerent parts of the plant to 

 each other : 



Tassels - 



Top stalk 



Butt stalk 



Sheaths - 



Leaves - 



Sheaths of husks 



Stalks of ears 



Silks - 



Roots 



Kernels - 



Cob 



12452- 

 Number of kernels on the above ear, 480. 

 Average weight of each kernel ... 7-226 



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. 



Relation of the kernels to the cob : 



Kernels 3468
