Dear Josh:

It was a pleasure to’ see you and Mrs. Lederberg at the
meetings, and to hear your material. I am still sorry that
I was too beat to stay up for all of your presentations.

As I told Miss Lively, I am sending a copy of the manu-
seript on methods which will appear shortly in Stain Technology,
and which you and she may find useful. I am also including
a preparation of mefatherium which I think will pverhans help
in orienting you in the analysis of your own material. I hope
SO. find that I do not have immediately available an extra
photopranhic copy of one of my plates, but I plan to have
some of these made and will send you one at a later date.

I find this business of getting reorganized after a
period of being away is a pain, but gradually thines are be-
coming propverly oriented.-

Jean joins me in hoping that thines are soing well with
you. We hope to see’ you soon.

Sincerely yours,
sas D. DeLamater, M. D.
