Dear Dr. Dubos: 
Thank you for your letter of October 30. From our 
brief conversation when you were at NIH for the Nutrition 
Conference, and also from reading both your Op. Ed. piece 
and most enjoyable book on Avery and DNA, I knew that you 
did not endorse the conments of the Natural Resources 
Defense Council on the recombinant DNA guidelines. 
Believing myself devoted to the original aims of the 
environmental movement, I, too, am appalled at its recent 
descent into sterile procedurallsm. Yet, your resignation 
from the Board of Trustees of NRDC is at once gratifying 
and disturbing to me. Without the continued influence 
and participation of such persons as yourself, who is to 
save the Salvationists? 
With my great respect and kindest regards. 
Sincerely, 
/S/ Donald 9 . Fredri;: :i.D.
