BEGINNINGS OF CO-OPERATION 85 



the survival value existing for separate living cells 

 before actual sexual union took place we can find a 

 logical beginning for the action of selection, which 

 would in turn, with present known values, result in 

 the establishment of the sexual phenomena as they 

 appear today. These fields have not been sufficiently 

 explored to allow for more than this flash of imagina- 

 tion, which future researches may verify or discard. 



At this point it would be well to pause and look 

 back over the road we have traveled thus far. The 

 charts, (7) shown as Figures 13 A and B, show that 

 most of our evidence has come from fairly well down 

 among the simpler forms of life. I have called atten- 

 tion to mass protection of one sort or another among 

 bacteria, planarian worms, goldfish and the simpler 

 crustaceans. Actually there are in scientific literature 

 good cases of mass protection for almost all the ani- 

 mals shown in these charts; and where exact informa- 

 tion is lacking, as for example among the rotifers, 

 this is a result only of lack of interest in conducting 

 experiments on this point with these animals. I have 

 little doubt that we could, overnight, demonstrate 

 mass protection from colloidal silver for rotifers; but 

 we have more interesting work to do. 



I have also shown active acceleration of fundamen- 

 tal biological processes as a result of numbers present 

 for sea-urchin eggs and larvae, and for various pro-
