The general average for all schools was parts per io,0(X). Six-ty-six per cent, of the observations fall below parts, which may beconsidered a very satisfactory value. Twenty-nine per cent, are be-tween and parts, which indicates a rather inadequate air change,and 6% are over 12 parts, which cannot be considered satisfactory. /=ER CENT OF 0B^ERVATI0N6,nFach C.
