Dear Jim:

| am terribly sorry and somewhat embarrassed that | couldn't
help you out on the Pontecorvo question but I'm afraid the
traumatic experiences of the last year have ejected most of
my recollections on the Symposium. {| should have thought
that there would have been some kind of notation in the card
File on the Symposium members which would refer to the receipt
of the manuscript but | assume that Evelyn would know as much
about this as could be known.

| am writing to ask you whether there happens to be a
cardboard drum of N-Z Casee still Sitting in the cold room.
We had Intended to take this along as the material would be
of very doubtful value to anyone else but it has not shown
up here and it may have been left in the cold room.

If it is there, might 1! ask you to have it shipped out to us
Express collect?

1 would not have bothered for this item alone but if you
are making that shipment, | wonder if it would be convenient
for you also to send us the Technicon pipette washer which
may still be sitting in the main sink. This would be on the
presumption that no one else is using it in the laboratory.
| Suspect this is right and | also think that it is in suf-
ficiently dilapidated shape now that anyone new you get in
would prefer to get a new washer. But use your own judgment
about this item.

Enclosed is a letter from Luria in which | would think
that you and the Genetics Department at Wisconsin might have
some interest although it is ofccosese, stil! on a personal
and informal basis. !f you have any thoughts on the matter
! suggest you do communicate them directly to Luria. While
| don't believe anyone at Wisconsin has had @ very intimate
association with Cold Spring Harbor as such, | am sure that
as Geneticists we would all be interested in its future welfare.

Ew bus fie

Yours as ever,

Joshua Lederberg
