THE UNIT GROWTH -CYCLE 33 



a new cycle begins. That is, the unit-cycle of growth 

 requires two units for its commencement, course, and 

 conclusion. It is simply an act of attraction followed by 

 one of repulsion, a unit diphasic reaction. The unit growth- 

 cycle may therefore be represented as below.

Here, A and B are two atoms mutually attracted. As 

 a result there is unit growth, AB. Repulsion is induced 

 between A and B, and each is restored or reproduced ; or 

 better, their original independence is thus affected. They 

 are now ready to begin a new cycle with each other, or two 

 separate new cycles with two new units. It is to be noted 

 that the repulsion which " reproduces " A and B is induced. 

 Were AB not interfered with, there would be no repulsion 

 and no reproduction. For these to occur there must be 

 present other atoms capable of upsetting the atomic attach- 

 ment and equilibrium of AB. Thus, the figure might be 

 drawn as below.

Here the atom C, being stronger in attracting power 

 on B than is A, induces the repulsion of A and attaches 

 itself to B. As a result the independence of A is reproduced. 

 Similarly, B may be reproduced in the presence of D, whose 

 affinity for C is stronger than B's. However,

may be taken as the diagram of the unit growth-cycle, 

 which, it is to be repeated, represents an Act of Attbac-
