It is possible this ought to be corrected in the same way as shown 
for the polarization. The correction, however would be of the third 
order and contain 6*; and this we drop throughout our investigation. 
For this same reason we are justified in replacing s* by o“ in the 
expression for the magnetization.

7. If e be the charge carried by an electron, then the current 
carried by the electrons is 
eNwt + ed Nwt + Led? Nw%, (a = 1,2, 3, 4). 
Adding the current carried by the nuclei, viz. —eNw*, we get 
for the resulting current: 
ed Nwt + 4 ed? Nw,
