April 18, 1968 Dr. Alice C. Evans 1661 Crescent Place, Apt. 604 Washington, D. C. 20009 Dear Dr. Evans: Thank you very much for your letter and reprint about chronic brucellosis. I do regard the pursuit of biological weaponry and our simultaneous neglect of the threate of world pestilence as two of our major problems of biological policy, and I intend to have much more to say about them in future. I was amused that you thought that I might not know of you, at least by repubation! Sincerely yours, Joshua Lederberg Professor of Genetics SAMWA (4161 7 3 vi SVMYA A
