Democratic Sentinel, Volume 4, Number 11, Rensselaer, Jasper County, 23 April 1880 — Vitiated Air. [ARTICLE]

Vitiated Air.

Dr. Willard Parker, in a lecture before the students of the College of Physicians and Surgeons of New York, used the following apt words: “If, gentleman, instead of air, you suppose this room to be filled with pure, clear water, and that, instead, of air, were exhaling twenty times a minute a pint of milk, you can see how soon the water, at first sparkling, would become hazy and finally opaque, the milk diffusing itself rapidly through the water. You will thus be able to appreciate, also, how at each fresh inspiration you would be taking in a fluid that grew momentarily more impure. Were we able to see the air as we are the water, we could at once appreciate how thoroughly we are contaminating it, and that, unless there be some vent for the air thus vitiated, and some opening large enough to admit a free supply of this very valuable material, we will be momentarily poisoning ourselves as surely as if we were taking sewage matter into our stomachs. ”
