Dear Joshua:

I talked with Dr. Waksman today after his return from
Boston. He is very interested in inviting Tom and he wants Tom to
send him a formal application outlining his present status, name of
the fellowship and plans for studies - all in brief; and enclose his
curriculum vitae.

I believe that the future for Tom looks bright here, and
within this large group of people and visitors he may find good friends.
Iam one, at least.

I enjoyed very much your visit here and talking with you
and Esther. In the meantime I have "induced" new SM mutants in K-12
strain\W- 1336 (F+) (%6-2) and today I have some recombinants between
this strain and W-1177 (F-) to check for SM resistance. I wonder what
would happen.

Best regards for you and Esther. .

Best regards,

-—

P.S. I shall appreciate receiving the parental strains to W-1702 and
W-1697 i.e. strains W-1 and 58-272. Would you tell me what are
the deficiencies of W-1 and W-1702 and what is the origin of W-1
and 58-272 strains.
