In whatever way the plants are compared, and however 

 minute the measurements that are made, the advantage remains 

 always with the plants from the large seed. The much greater 

 uniformity of growth cannot be shown in the table without 

 taking too much space, but it appears all through the details 

 given in the original paper. To give one or two instances : 

 Of the ten plants taken up on June 17, all but one of those 

 from the large seed had its leaves as given in the table, and the 

 odd one had twelve leaves ; on the other hand, of the plants 

 from the small seed some had ten, some eleven, and some twelve 

 leaves, and one had thirteen. The uniformity of the plants from 

 the large seed was marked. At the rate given in the above 

 table, the increased yield per acre of seed of the first quality 

 that may be obtained by the use of large seed rather than small 

 would be 250 Ib. A similar course of experiments with Peas 

 gave the following results :
