HEREDITY 199 



exist, nor the light and colours, so beings, on re- 

 production, obey the rhythm of force, and each 

 being is a vibration of the rhythm to which it owes 

 its origin. 



Nature reproduces indefinitely plants and 

 animals just as the sea impels its waves. From 

 the infinitely small to man, there exist as many 

 classes of rhythms as of organisms. 



Bearing in mind what I have said in speaking 

 of health in its relation to the general laws of 

 mechanics, man, in order to live in a normal medium, 

 will keep the equilibrium of his harmonic cellular 

 mechanics in consonance with the laws of universal 

 harmony, and the sons will reproduce the same 

 equilibrium of formula N as their progenitors, for 

 they will be the reproduction of the same force, 

 adjusting itself to the same rhythm. 



Man is born, lives, and dies in a limited portion 

 of time and space, since he represents only one 

 vibration, like other rhythms destined to vibrate 

 and die away, being subsequently renewed in the 

 universal energy. 



In the present state of social organisation, among 

 the members of which formula N (A, B, C, D) is 

 altered, the children are ever tending to modify 

 and lose the parent form, until in many cases, as in 

 certain families, in the third or fourth generation 

 they are either not reproduced or die off prematurely.
