With your tremendous com- prehension of the present coverage of the field, I am sure that such an outline from you would very ably serve as a directional finder at this time. as We shall look forward to hearing from you with deep appreciation, and with my cordial, warm regards, Most sincerely yours, ETM: jn Executive Director CC: Doctor Hilary Koprowski lu, Cent om J Calf Lan ac ath pel ptt i
