Dear Dave:
Thank you for your kind, friendly letter of the Istf

It would be premature for me to make or encourage any further
comment now: I really haven't thought very seriously about Wister
yet, and em waiting to heave a chance to discuss it with Koprowski.
I am glad to hear the old institute ig being revitalized, and I
do think Koppowski would be a remarkable choice for it, In thinking
about this, of course I have to ask myself not only how attractive
and stimileting the situation would be, but also whether it would
warrant the uprooting fron Wisconsin, which has been very pleasant.
and rewarding as a place to work. I do think it would be unfortunate
if, at this time, I atest misled uuyth anyone into thinking I was actively
contemplating the move: for the next few weeks, I will however be
asking advice and finding out what I can that would be relevant. Your
letter has been quite helpful so far, and I trust I can call on you arafn
for your counsel if the deliberations co further,

Yours sincerely,

Joshua Lederbers
