Dear Dr. Nirenberg,

    Thank you for your letter of March 12.   I under-
stand very much how difficult it must be for you at this
time to establish plans so far ahead, but we need to know
definitely who will be coming in the laboratory.  I hope
very much you will be able to come sometime here and I
keep you some laboratory space for the year 1964-1965 as
you suggest.

   We shall probably meet in the Royaumont meeting
this summer.  I hope it will be possible at this time
to make more precise plans,
    With best regards,
                   Your.,s,
