Dear Dr. Fredrickson: 
Thank you for your letter relative to the 
Advisory Committee on the Recombinant DNA Guide- 
lines. It was indeed a stimulating experience 
for me, and I appreciate being involved. 
Should there be an occasion where I could be 
helpful in the future, I hope you will call on me. 
I am going over the reports with great interest. 
Good luck to you in the difficult decisions you 
must make.
