Dear Dr. Gartland: 
I an vrltlrv; In support of the proposed amendment to section I~D of 
the NIH guidelines co-authored by Prof. Richard Goldstein and Dr. Richard 
Novlck that would prohibit the use of molecular cloning for devolopnent 
of biological weapons. I support this amendment very strongly, especially 
at a time when biological weapons are becoming thinkable once again. 
Please, no more awful Inventions for death. 
Sincerely,
