Dear Dr. Tamm:

I am enclosing a copy of a letter from Dr. Crick
at Cambridge, which presumably settles our previous discus-
sion very mich in your favor. I wish I could recall some of
the qualifications that I had in mind, but they are out of
order at the present time.

I will be very happy to hear from you concerning
the scientific issues on biological exploration of the
planets. The time, of course, is growing very short.

With best regards.

As ever,

P. 8. You will, of course, take note of my new address, where
I have been happy to be for the past week.
