January 16, 1957 Mr. Eugene Davidson Yale University Press New Haven 7, Conn. Dear Mr. Davidson: Thanks for your kind letter of January 11. Miss Yerkes's editing is indeed a great help. She has considerably improved my manuscript. For the questioned reference to the scientific basis of econometrics -- or, more precisely, to the lack of such a basis -- I suggest the following wording: "which cuts the ground from under their line of reasoning." I highly appreciate the great interest you take in the publication of my new book as you have already done in my earlier publications. With all good wishes for a Happy New Year, Sincerely yours, LM/ms
