Dear Dr. Herczeg,
Thank you for yours of November 22 and the paper clips
you sent me. I am glad you agreed to my arguments and I am
also glad to let you know that meanwhile I got a letter from
Professor Heinrich. Upon the publication of the second
impression of my book "International Economic Integration"
I shall have the pleasure of sending you a copy.
Yours faithfully,
(J. Tinbergen)
