Dear Professor Lederberg:

In the course of my work with Harvey Brooks in discussing
the need for assessment of technology I wrote the attached brief
paper on trace element contamination of the environment which I
believe is the one in which you expressed an interest. This was
done quickly and is not very complete. You are certainly welcome
to have it.

Sincerely yours,

E. Creutz
