 we obtain at last, the comaion factor At AE being left out, 



Ï + " t + " I + s + ^ g + ^ % + 4: - V (/) + □ (./) . 



which is the fundamental f equation in statistical mechanics. It may even more 

 shortly be written in the form 



(4*) I = V (/) + □ (/) . 



It remains to deduce the analytical expressions for V (/) and □ (/) .
