Letter of Urey Concerning Visit of Timofeyev.

Dick Youngsays that there is real interest at Ames in having him
speak. Klaus Keil and William Quaide of the Space Science Div-
ision have ans work on meteorites, Keil in particular would
be glad to chair a meeting at which Timofeyev would speak. He
however would not like m do this under circumstances which would
prevent him from inviting Timofeyev to visit his labs at Ames.
He therefore requires that Timofeyev would be cleared to visit
Ames. This can best be done by having Harold Urey contact Walter
Peterson of the Ames Research Center, extension 2498, directly.
If this can be done, I suggest that the meeting be held at Ames
with Keil as host. We could jointly sponsor it if this is a help

for any reason - such as expenses or honorarium.
