192 SUPER-ORGANIC EVOLUTION 



anatomy as a demonstration of the rhythm that 

 governs the animal world. Sons are like fathers 

 because they are notes of one and the same rhythm, 

 and the rhythms are repeated under normal 

 conditions. 



In spectral analysis are shown the same rhythms, 

 for not only has each body its lines regularly invari- 

 able, but in some spectra, as in that of hydrogen, the 

 disposition of their lines is according to a formula 

 of perspective. 



To further justify what I have said and what 

 still remains to be said I am about to refer here 

 to the diagram of Sir William Crookes. 



This professor says in The Genesis of the Elements : 

 " I must crave your attention to my diagram, in 

 which I have slightly modified the primitive tracing 

 of Professor Reynolds. I have represented the 

 oscillation of the pendulum decreasing gradually 

 according to a mathematical law. Moreover, I 

 have interposed between cerium and lead another 

 semi-oscillation of the pendulum, which makes the 

 oscillations more symmetrical and brings gold, 

 mercury, thallium, lead, and bismuth to the side 

 where they are completely in harmony with the 

 elements of the first group. 



" The chemical elements are arranged, according 

 to their atomic weights, on a central vertical axis, 

 equally divided.
