Publisher's Synopsis
Excerpt from The Journal of the Franklin Institute, Vol. 144: Devoted to Science and the Mechanic Arts; Nos. 859 864; July December, 1897
I should say at this time, perhaps, that some two years ago experiments were carried on for some time, by a com mittee consisting of Dr. S. Weir Mitchell and Dr. J. S. Billings, the results of which were published by the Smithsonian Insti tution. The object Of these experiments was to find out to what the drowsy feeling that we have when in an ill-ventilated place was due, and also to find out what produces death from lack of ventilation. Those studies seem to indicate that the amount of fresh air that I have mentioned, namely, cubic feet of air per person per hour, is large, and that possibly a smaller figure would be satisfactory. These authorities, how ever, are very cautious; they give us no definite figures. They apparently could not prove the existence of, or at least could not isolate any poisons in the air that would produce death. They seem to indicate that the drowsy feeling is due principally to increase of carbonic acid and diminution of oxygen. And, finally, they say in so many words that it would be a mistake to assume from their experiments that the ordinary figures applying to ventilation are widely in error.
