Dear Doctor Lederberg:

Thanks for the additional instruction sheets,
We have every intention of developing this into a
substantial research project, and applying for a subsidy
from the U. S. Public Health Service or other sponsor,
Just now we are tied up in negotiations with Camp Detrick
on another project which, if it zvoes through, will use
up all the personmel and space we have. Until this project
is settled, we have only spare time for the silica gel study
but I do want to keep it going so as to be able to expand
it to a major operation at first opportunity.

Sincerely yours

Firetree ae Ql. Lhect+
