1 MATRIX FOR THE GENERATION OF THE PRIMARY ORGANISMS 229 



or difficult-reversible change was brought about and the changed 

 structure was able to exert a physicochemical effect stronger than the 

 original one, then the new structure would "assimilize" the sur- 

 rounding masses. By the repetition of such a production of stronger 

 structure the masses would become stronger and stronger in their 

 structure, and more and more fitted to act as strong assimilase. 



In short, the evolution of the primary organism at the primeval 

 stage might be quite similar to that of the secondary organisms or 

 viruses. In the case of viruses, however, the matrix in which they 

 have been evolved is the preexisted, perfect protoplasm, which itself 

 is the strong assimilase and in which various differentiated mechanism, 

 as for example, that of the spreading of changed structure, are already 

 provided, so that the stronger structure acting as the viruses would 

 easily be produced, whereas in the case of the primeval organisms, 

 as the matrix itself was quite incomplete, the enhancement of the 

 strength of the structural pattern would be much more difficult ; 

 accordingly far longer span of time would be required for their 

 evolution than for the virus. 



As fully discussed in the previous Part, when a virus continues 

 to multiply in the same kind of host cells, the virus structure is to 

 be gradually assimilized by the host protoplasm until it becomes 

 extinct. In order to avoid such a fate the virus must frequently 

 change the host. This may account for the difficult situation in the 

 continuance of their existence. The same might hold true for the 

 primeval primary organisms. 



The state in which the protolasm-like masses accumulated on the 

 bottom of the ocean of the primitive age, exerting mutually structural 

 influences upon one another, might be similar to the state of the 

 viruses multiplying always in the same kind of cells. Therefore, even 

 strong structures which might appear and spread in the accumulated 

 massses would likely be influenced in the long run by the weaker 

 masses existing in the overwhelming majority until it became iden- 

 tical to the weaker masses, or at least it became weaker in the 

 structure. 



In order to avoid such a decrease in the structural strength, the 

 mass which might acquire a strong structure would find it necessary 

 to move to another accumulation of the masses of a different type 

 corresponding to a different kind of host cells in the case of viruses. 

 In the movement of masses, the water in motion might play an im- 

 portant role. Thus, if the masses on the bottom of the ocean was 

 carried near the shore, say, by a tidal current, they would always 

 have good chance to contact with other masses of different structures 

 by the constant motion of waves. If there was a structure in common
