Dear Bill: 
In connection with Winston Brill's recent letter re- 
garding lowering of containment for non-pathogenic pro- 
and lower eukaryotes, I would like to say that I concur 
but would prefer that the lowering be to P 2 rather than 
PI because of the large variety and number of organisms 
that will be affected. 
Incidentally, I regret that I will be unable to attend 
the January 8-9 meeting.
