Dear Dr. Fredrickson: 
As a working virologist for nearly thirty years, I am writing in 
support of the revised safety guidelines for recombinant DNA research 
published in the Federal Register of 28 July 1978. The final guide- 
lines should be issued without delay and implemented promptly if Con- 
gress does not pass a bill dealing with recombinant DNA research. 
I believe there is more than sufficient information available 
now that warrants liberalization of the 1976 safety guidelines. 
Depending on the course of events by upper echelons of government, 
I hope you will implement the revised guidelines at the earliest 
time so as to move forward this extremely important area of biomedical 
research.
