Dear Dr. Gartland: 
I am writing to offer my strong support for the proposal to convert the 
NIH Guidelines Into a non-regulating code of standard practice and to reduce 
the recoomended containment level for some experiments, as put forth by Drs. 
David Baltimore and Allan Campbell and published In the Federal Register of 
Friday. March 20. 1981. I agree strongly with the justifications for this 
proposal provided by Drs. Baltimore and Campbell.
