118 HISTORY OF THE OCEANS 



by Hull (1960) that photosynthetic degradation must accompany 

 photosynthetic creation of complex compounds from simple 

 molecules. I have already pointed out (Bernal, 1960) that the 

 removal of the reaction products would also help to preserve them, 

 but Mason's hypothesis would very much strengthen my argument.
