Dear Josh:

I am sorry that I wasn't able to come to the session last
weekend, but things had just piled up on me and I couldn't
get away. I haven't had a chance to talk to Cl yet about
what transpired, but I suppose that you will issue a memor-
andum covering the discussion at the meeting so that I will
have an idea about the direction that was taken.

The other matter that is pressing me now is a letter from
Seeley regarding the Sagan manuscript that I sent you sane
months back. Apparently you haven't taken any action on it,
and I wonder if it would be possible for you to return it to
me so that we may decide what to do with it. Many thanks.

reetings and very truly yours,
WEE
