Dear Dr. Gartland: 
I have become aware of the cunendment to NIH 
Guidelines, prohibiting the construction of biological 
weapons by molecular cloning, offered by Drs Richard 
Goldstein and Richard Novick. 
For all of the reasons that their arguments raise 
I can strongly endorse this amendment. I hope that your 
DNA Advisory Committee agrees with this stand and uses 
its considerable clout to add another safeguard to the 
recombinant DNA technology and politics.
