Page 303 - The feeling of it to my lungs was not sensibly different from that of common air, but I fancied that my breast felt peculiarly light and easy for some time afterwards. Who can tell but that, in time, this pure air may become a fashionable article in luxury? Hitherto only two mice and myself have had the privilege of breathing it (24).
Page 154 - Any fireplace or furnace which does not as far as practicable consume the smoke arising from the combustible used therein, and which is used for working engines by steam, or in any mill factory dyehouse brewery bakehouse or gaswork, or in any manufacturing or trade process whatsoever; and Any chimney (not being the chimney of a private d'welling-house) sending forth black smoke in such quantity as to be a nuisance...
Page 308 - The neighbourhood chosen should be dry and high ; the soil, generally of a light loam, a sandy or gravelly bottom ; the atmosphere is in such situations comparatively free from fogs and dampness. The patient ought never to be deterred by the state of the weather from exercise in the open air; if wet and rainy, a covered » vehicle should be employed, with open windows. The cold is never too severe for the consumptive patient in this climate ; the cooler the air which passes into the lungs, the greater...
Page 164 - Every blade of grass, and every branch of tree, would drip with moisture, deposited by the passing air, our dresses would become wet and dripping, and umbrellas useless, but our miseries would not end here. The inside of our houses would become wet ; the walls and every object in the room would run with moisture.
Page 308 - The only gas fit for the lungs is the pure atmosphere freely administered, without fear ; its privation is the most constant and frequent cause of the progress of the disease. To live in and breathe freely the open air, without being deterred by the wind or weather, is one important and essential remedy in arresting its progress — one about which there appears to have generally prevailed a groundless alarm lest the consumptive patient should take cold.
Page 129 - The injurious effects of such airobserved appeared to be due entirely to the diminution of oxygen, or the increase of carbonic acid, or to a combination of these two factors. They also make it very improbable that the minute quantity of organic matter contained in the air expired from human lungs has any deleterious influence upon men who inhale it in ordinary rooms, and, hence, it is probably unnecessary to take this factor into account in providing for the ventilation of such rooms.
Page 153 - It is this horrid smoke which obscures our churches and makes our palaces look old, which fouls our clothes, and corrupts the waters, so as the very rain and refreshing dews which fall in the several seasons, precipitate this impure vapour, which with its black and tenacious quality spots and contaminates whatsoever is exposed to it.
Page 129 - In ordinary quiet respiration, no bacteria, epithelial scales, or particles of dead tissue are contained in the expired air. In the act of coughing or sneezing, such organisms or particles may probably be thrown out.
Page 126 - ... by one of the men contriving to force his way on deck, and to alarm the mate, who was called to a fearful spectacle : seventy -two were already dead, and many were dying ; their bodies were convulsed, the blood starting from their eyes, nostrils, and ears.
Page 129 - The minute quantity of ammonia, or of combined nitrogen or other oxidizable matters found in the condensed moisture of human breath appears to be largely due to products of the decomposition of organic matter which is constantly going on in the mouth and pharynx. This is shown by the effects of cleansing the mouth and teeth upon the amount of such...
