I have no reason to change my views now. The present proposal 
seems eminently sensible and prudent. It transforms The Guidelines from 
regulations (which they were) to guidelines (which they should be). My 
own early concerns that some recombinant DNA experiments might carry 
risks have long been dissipated. The data, discussions and experience 
of the last six years have convinced me that our earlier concerns are no 
longer warranted. I now believe that there is more to fear from the 
intrusions of government in the conduct of scientific research than from 
recombinant DNA experiments themselves. Consequently, I welcome the 
changes put forward by Baltimore and Campbell and hope that RAC will 
approve them pronqitly. 
With best wishes. 
Sincerely,
