14/9/59 Dear Lederberg, One of these days, I hope to prepare another edition of my cytology book, and am collecting material all the time. I would be very glad to have, for this purpose, an original photograph of one of your copulating bacteria in action. Naturally, knowing that you have a poor opinion of the book, [END PAGE ONE] [BEGIN PAGE TWO] I will confine myself to stating exactly what it is, in your own terms, so that you need have no fear of my giving it a slanted interpretation. Several people could, of course, provide such material, and I have a couple of cultures myself that do so; but since you did discover the phenomenon, and proved it in such an elegant manner, I think the book should carry your picture. I hope you like Stanford; please remember me to Clifton, also Mrs. J.L. Yours sincerely, Kenneth Bisset
