Dear Josh:

I finally got back to Frederick and thus get a chance to
reply to some of your accumulated correspondence. First of all,
I want to thank you for the copy of the manuscript. With the
help of the dissecting microscope, i have been able to decipher
the material quite successfully. as far as the assembly for
holding the molecular filters is concerned, you should return this
item to Dr. 0.E. Bolduan, PD Division, Camp Detrick, Md. ‘

I expect that Mr. Reifsnider has informed you about the
manner in which we are planning to handle the extension of
your contract. Since Mr. Reifsnider is on vacation I have
not been able to check with him on this, but in case there
are any questions, do not hesitate to write to me inmediately.

We had a very pleasant time at C.S.H. and some of the
results which I obtained in regard to amino acid levels in
cells treated with mutagenic agents (415) might be of potential
intereste .

With best regardse

Sincerely yours,

(Oo
