Dear Dr. Velikovsky:
In the rush of flying to Zurich next week to give a course of lectures at the University of Rome I have neglected my correspondence. Please excuse my delay in thanking for your letter of Dec. 6 and for letting me see the enclosed rebuttal.
Best wishes for your new book.
Robert H. Pfeiffer
I was gald to see you in New York.
