Dear Sir: 
I have read the proposed changes of the NIH guidelines for 
recombinant DNA research. I would like to say that I am in 
complete agreement with all the recommended changes proposed by 
the NIH Recombinant DNA Advisory Committee. 
I trust that you will take further action on these proposals 
since the long overdue relaxation of the guidelines has seriously 
held up many experiments in this area of research that would in 
the long run be extremely beneficial to mankind.
