Dr. William J. Gartland, Jr. - Page 2 
In summary, I would like to see the regulatory aspects of the guidelines 
kept in place for a bare handful of experimental systems. This would 
serve two purposes: keeping the broadly acknowledged potential dangers 
under external scrutiny, and retaining the basic ORDA-RAC structure in 
place so that it can easily respond to future developments. 
Sincerely yours.
