In closing I wish to say that I very much appreciated your article in the 
July 1979 Recombinant DNA Technical Bulletin and can sympathize with the position 
into which you and the NIH have been put by the "recombinant DNA affair". 
However, I hope that when the Guidelines are finally "preserved under glass" 
they will not be interpreted soley as response to a "social abberation" but 
will rather be seen as testimony to the fact that the scientific community 
did not bow to expedience, but rather put public safety first even though 
they considered likelihood of threat to that safety to be extraordinarily 
low. 
Sincerely, 
Bruce R. Levin 
Associate Professor of Zoology
