Dear Dr. Twitty: |

I ms oaly waiting for your reply, just rechdved, to confirm that we
will be happy toaparticipate in next sumser's Growth Sympoaiua. You have
an excellent pro if most of which is indeed of direst interest to us.
In view of the topic we have, perhaps reckless cliosen, I hope we will
not be too presumptucus in commenting on fields for which Billinghas, on
the one hand, and Relbruackg on the other might be better qualified.

My only reservation 4s that it would be extremely embarrassing, should
manuscripts be required, if these had to be subsaitted before the end of

the summer.
° Yours sincerely,

Joshua Lederberg
Professor of Genetics
