For often the attempt to secure pure air by one class of persons brings chills, colds, and disease on another class, from mere ignorance or mismanagement. To illustrate this, it must be borne in mind that those who live in warm, close, and unventilated rooms are much more liable to take cold from exposure to draughts and cold air than those of vigorous vitality accustomed to breathe pure air.
The decayed animal matter sent off from the skin and lungs in a close, unventilated bedroom is one thing that generates these zymotic diseases. The decay of animal and vegetable matter in cellars, sinks, drains, and marshy districts is another cause; and the decayed vegetable matter thrown up by plowing up of decayed vegetable matter in the rich soil in new countries is another.
Like every other householder in the town, whatever his religious convictions might be, Cazaban, in the pilgrimage season, let his bedrooms, surrendered his dining-room, end sought refuge in his cellar, where, heaped up with his family, he ate and slept, although this unventilated hole was no more than three yards square.
Cairo strikes one as unventilated and unsterilised, even when the sun and wind are scouring it together. The tourist talks a good deal, as you may see here, but the permanent European resident does not open his mouth more than is necessary sound travels so far across flat water. Besides, the whole position of things, politically and administratively, is essentially false.
Snagsby passes along the middle of a villainous street, undrained, unventilated, deep in black mud and corrupt water though the roads are dry elsewhere and reeking with such smells and sights that he, who has lived in London all his life, can scarce believe his senses.

It is here that the external respiration or the exchange of gases between the capillaries and the air cells occurs. VENTILATION. It is agreed by all persons who have investigated the subject, that unventilated stable air is injurious to animals.
It never occurred to him to complain of nubbly bed and ill-cooked steak and crowded and unventilated dressing rooms; but it always struck him as being absurd that such should continue to be the lot of one predestined to greatness. There was some flaw in the working of destiny. It puzzled him.
I can hear myself droning out in detestable English a meaningless portion of that endless journey of the pious AEneas; can see Gene Hollister, with heart-rending glances of despair, stumbling through Cornelius Nepos in an unventilated room with chalk-rubbed blackboards and heavy odours of ink and stale lunch.
Now the carbonic acid in the breath which comes out of our mouth is warm, lighter than the air, and rises to the ceiling; and therefore in any unventilated room full of people, there is a layer of foul air along the ceiling. You might soon test that for yourselves, if you could mount a ladder and put your heads there aloft.
