Diagram 4 shows graphically the results for the seminormal phenolic 

 solutions at 19° C. The diagrams for the other solutions are exactly similar 

 in form. 



* The rate of entry of the solution also falls off as the time proceeds, but this is 

 obviously because they are all the while getting fuller. It is evident that the time is 

 only a secondary factor ; the degree of fulness, as indicated by the weight to which the 

 seeds have attained, being the fundamental one.
