August 26, 1952 Dear Dr. von Mises: Thank you for your letter of August 22. I shall communicate with Dr. Kelsen concerning that one passage which I do not understand ( Urteilen and beurteilen. ) My present difficulty is to find a copy of the book. I had a copy from the Library of Congress but had to return it. Would it be possible for you to lend me your own copy for a while or do you need it? Or could you lett me know where I may outain a copy? I find that I can work on this only a few hours a day. Consequently, it will take me considerably more time to complete the translation than I had anticipated. Please, remember me to Mrs. von Mises. With my best wishes, Cordially, Felix Wittmer 395 Grove Street Upper montclair, N.J.
