SUMMARY. 



Before proceeding to summarize the results of 

 this study, it may not "be out of place to emphasize the 

 application, in this case, of certain fxindamentai principles 

 sometimes seemingly neglected. These points emphasized in 

 this paper are "based primarily on the results of the experi- 

 ments of this particular study. Up attempt is made to make 

 the statements of this summary applicable to all plants, nor 

 to all v;heat seed, nor even to all "Marnuis" wheat seed. They 

 refer simply to this lot of wheat seed in these tests and to 

 the first phase of development, ahout 110 hours from the 

 beginning of the soaking of the seed. Similarly, they 

 refer only to the maintained temperatures here employed, 

 to, the total concentration (equivalent to about 0,1 atm. 

 of osmotic pressure) of the feblutions used, to the 126 

 different salt compositions outlined in the "Plan for 

 Cooperative. Research, " to the absence of light from the 

 culture chambers, and to the various other details that 

 may have been effective in controlling the results of this 

 experimentation. The present paper is simply a report on 

 the results secured from these tests and on the relations 

 that obtain among them. "Aether other seed mifht exhibit dif- 

 ferent relations for this same physiological phase o:^ develop- 

 ment and for these treatments Is of course not predictable
