The electric and the magnetic forces of the ether vibrations, 
emitted by the element are proportionate to [Mi]. The emitted 
energy is therefore proportionate to [M2]. This energy proves to be 
on an average the sum of the quantities of the energy, which every 
molecule would emit, if it were alone in space. 
Let us now examine what would be the distribution of the electric 
and the magnetic forces, the components of which we represent by:
