Dear Josh and Esther:

I am now planning to arrive in Palo Alto by car on
Thursday morning, April 25th, driving from Berkeley. Would you
be so kind and tell me once more which exit to take from the freeway
and how to reach the campus, since I lost my previous notes?

I do not know how long it will take from Berkeley to
Palo Alto but I should expect to arrive sometime between 10 and 11
o'clock in the morning; where should I reach you at that time?

May I ask one more favor of you? I would like to meet
Grofetein while I am in Palo Alto and talk to him about several problems

of mutual interest; could you check to see if this could be arranged?

Iam really looking forward to this brief interlude in
California and particularly, to seeing you both again.

Warmest regards,

Singfrely yours,

Hilary Koprowski, M.D.
Director
