Fig. 1. A sketch showing an arrangement of genes contained in individuals; the rosary- 
bends representing genes, which change from time to time as if they were in one current of 
communication in their essence. Although in the above case, as I was trying to explain my 
idea in the simplest way, I regarded the rosary as a line in one plane, yet we may assume that 
the same rosary may be extended in boundless space of three dimensions; at the same time, 
our rosay-beads may be regarded as solid bodies of three dimensions.
