July 10, 1950

Dear Solovine,

I received your letter of June 30 and agree to all your proposals. The matter of spectral rays is of course explained by the fact that I had nothing at all do with the publication of my essays and the publishers had no notion of the subject. I am curious to learn just how far our opinions on religion differ. I can not imagine how, basically, our opinions could be widely divergent. If that is the way it appears, I probably failed to express myself clearly.

Personally I am getting along well, though my sister has retrogressed, without suffering much, however.

The next edition of the Appendix is still being held up because I can find no completely satisfactory proof for the compatibility of the new field equations. Hence the delay.

With my cordial greetings,
Your
