My dear Bisset:

Thank you for your letter of the 5th. Of course you may use any
photograph that I have published, subject to the concurrent assent of
the copyright-holder, if any. You will not think me unduly cautious
i? I particularly request not only the usual attribution of source, but
some care in distinguishing added interpretation from my own assertions.

I have been particularly interested to read your recent accounts of
cell structure, especially in M. oryophilus, and there seems little doubt
of the validity of your criticiem in respect to the misidentification
of the cell wall. I may still hope, however, that some rationale of mitotic
division or ite equivalent will be left after you and “one supporter" have
retired from the arena. Please do remember to continue the mutual exbhan ge
of publications from our respective laboratories.

Yours sincerely,

Joshua Lederberg
Professor of Genetica
