Dear Dr. Gartland: 
I vrlte In support of the proposal by Drs. David Baltimore and Allan 
Campbell to modify existing NIH Guidelines on Recombinant DNA Research. 
The proposal Is based soundly srrlte "....neither experimental evidence nor 
solid theoretical arguments have been advanced to support the position that 
recombinant DNA research poses any danger to himan health or to the Integrity 
of the natural environment". There Is no question that this statement Is 
valid. In view of this fact, reduction In regulatory activity In this area 
should be undertaken without delay. 
Your sincerely.
