Dear Dr. Lederberg:

You are quite correct, I did do a review of the acridines
which appeared in Medicine, Vol. 23, p. 79, 194. Unfortunate-
ly, I have no reprints of this article and therefore cannot
comply with your request. As you know, Dr. Adrien Albert re-
cently wrote a book on this subject but then, clearly, I am
proposing coal for Newcastle, in view of the presence in your
group of Dr. Rubbo.

I do very mich appreciate your willingness to exchange
publications and with that thought in view, I am sending to you,
under separate cover, a copy of "Biological Antagonism’.

With all good wishes for the coming holiday season.

Sincerely yours,

Cuate J. Waly
