This work of Delassiis exactly confirms the results of detailed experi- 

 ments reported by Hicks and Dabney(4i) in 189G, who compared large 

 and small seeds of Soy Beans and Garden Peas respectively. The seeds 

 were planted in pure sand in a greenhouse, equal amounts of a culture 

 solution which contained all the elements necessary to plant growth being

 The upper curves represent plants from heavy and the lower those from hght seed.

given to the plants, which were kept from first to last under identically 

 similar conditions so far as possible. In result they found that the large 

 seed produced plants which gained continually upon those from the 

 small seed and finally gave larger and more vigorous plants and a better 

 yield as is shown by the curves represented in Figs. 1 and 2.
