Professor Joshua Lederberg
Genetics Building
University of Wisconsin
Madison 6, Wisconsin

Dear Professor Lederberg:

I was very much impressed with your carefully calculated
reasoning in your memo accompanying your letter of
January 31. I am very thankful to you for bringing
to my attention a future aspect of the scientific
caution that must be observed in the extension of

our exploration into space. I can assure you that

I will bring this to the attention of the proper
authorities in the United States. In the meantime,

I will also endeavor to bring this to the attention
of the scientists of the International Council of
Scientific Unions with the hope that an international
position which will protect the scientific integrity
of space objectives can be confirmed.

. Sincerely yours,

1
