Dear Dr. Fredrickson, 
I wish to voice my support for the revisions listed in the Federal 
Register of November 30, 1979, which are concerned with recom- 
binant DNA experiments. I am referring to those revisions stated 
in Section III-O which reduce the registration and containment 
requirements for experiments involving E. coli K12. 
Please be aware that delay in implementation of the revisions can 
only hamper the completion of those experiments now in progress. 
Sincerely 
[ 453 ]
