0.5 for the dry condition. It appears, then, that these physio¬
logical observations reveal no difference in the reaction of the body
to the air conditions studied. Possibly more sensitive tests or more
rigorous conditions would bring out a difference. It must be re¬
membered in this connection that it was not the purpose of the
commission to discover what extremes of humidity could be borne
by the human organism. Since the study attempted to solve a
practical problem no humidity conditions were used in the labora¬
tory that might not have occurred under ordinary circumstances.
As a matter of fact an indoor humidity of 50 per cent, or 20 per cent,
would only rarely be found to exist. At least these votes and
physiological observations show that for practical purposes the
ventilation conditions studied are not noticeably uncomfortable or
dangerous to health during the exposure period of this experiment.

^ Supposed "dry" weeks too moist to be included as dry.
2 Average humidity in dry weeks 33 per cent.
