Dear Edouard:

| am surprised you don't have the reprint, which Is now enclosed.
Are you missing any other recent papers (e.g. In the bibliography
of "A view of genetics''?

We would look forward very much to coming to Geneva; however it
would not be a matter of 1960-61, so you need not :e concerned to save
space. We should be able to give you a year's notice of it to make sure
of any arrangements.

We likewise enjoyed your visit and have felt greatly enlightened
in understanding the bacterial nucleus.

With best wishe:,

Joshua Lederberg
