O'TIN SP D'ANT ET VERITAS YALE UNIVERSITY PRESS At the Earl Trumbull Williams Memorial NEW HAVEN CONNECTICUT January 22, 1957 Professor Ludwig von Mises 777 West End Avenue New York 25, N. Y. Dear Mr. von Mises: Thank you for your good letter and for returning the second batch of manuscript so quickly. All the rest of the material goes to you today by express, insured for $500. When you have been over it and returned it to us, won't you name some date, a little after our probable receipt of it, at which it may be convenient for you to come to New Haven and discuss any remaining problems? It will be helpful, of course, if you will allow me time before hand to read over your marginal com- ments and clean off all answered queries. Won't you please leave my slips attached to the pages even after you have answered their queries? I have difficulty in remembering what the query was unless it is still there. Also, if you should retype a page, will you leave the old type- script in the manuscript along with the new? Can you possibly send me the two void pages, which I believe you have retyped, in the early part of the manuscript? Sincerely yours, yerkes RY:jbl
