Dear Joshua:

Thanks for your letter telling about your new and interesting
work with the actinomycetes. That field certainly needs a lot
more attention.

The lyophil business is out of my field so I have turned your
letter over to Dr. Raper, Head of our Culture Collection Section,
who should have an answer for you soon.

One of these days we will get together at a meeting and talk
over those days at Columbia.

Best wishes for the holiday season.

Sincerely yours,

Sy onda,
