It is very encouraging that the threatening term destroys itself.
After all, the electromagnetic field laws read exactly the same way with you as
in my theory! You, too, have an absolutely normalized potential , and
the field current is connected with it according to the equation —
On the whole, I naturally am glad that I now meet you on the same purely specu-
lative paths which you were earlier always protesting
against.[5]
Indeed—who
knows whether a compelling decision can be reached by following this route!
With best regards, your truly devoted follower and opponent,

Dear Colleague,
I did, of course, miscalculate in the additional terms for the current in the sym-
metr. part of
