Professor Hans Riechenbach,
California.

Dear Reichenbach,

Thank you very much for your good letter of March 28th and for the accompanying literature. I will, as soon as I can, study carefully all that you say on the subject of probability.

I perceive already that you are right as to the mathematical error that I committed on page 416. Most of the other points seem more capable of being argued.

I am sorry, however, that I overstated your relation to Mises.

I decided not to go to Argentina not for any public reason, but I could not spare the time.

All best wishes from us all.

Yours very cordially
