From this it may be seen tliat tlic ab.soliitc weight of a seed Jias 

 an intimate relation with its productive power but the latter has 

 almost no relation with its specific gravity. Moreover, the results 

 above recorded confirm those obtained by Hcllriegel, Wollny and 

 other experimenters.
