Dear Dr. Fredrickson: 
I have studied the proposed guidelines concerning Recombinant 
DNA Research (Federal Register, November 30, 1979) and wish to 
express my agreement with the indicated changes. The proposed changes 
in Section III-O are of particular significance because they represent 
much more realistic restrictions than the previous guidelines. It is 
apparent that the committee responsible for these decisions is 
exercising good judgment and should be commended. 
Sincerely, 
Duane L. Pierson 
Assistant Professor
