Dear Sir: 
I would like to take thla opportunity to affirm my belief that the 
propoeed revlelona appearing In the Federal Register dated December 4, 
1981 promulgated by the Recombinant DNA Advisory Committee be adopted 
without delay. Substantial experimental evidence dictates the wisdom 
of this decision. 
I appreciate the opportunity to comment upon this important

Sincerely yours
