The equation of configuration (B) depending on the assumed form of 

 the compound molecule 



If we suppose r" = 1 (compound molecule of same size as molecule 

 of element), the cheapest and most probable result will be found, 

 from making e^ = 0, a^ = 0, from which we obtain 



Mi

as the general relation between the atomic weight and periodic time 

 of the tetrad.
