Страница 12 - ... nitric acid, thus working in every case in a manner the inverse of that which is peculiar to animals ? If the animal kingdom constitutes an immense apparatus for combustion, the vegetable kingdom, in its turn, constitutes an immense apparatus for reduction, in which reduced carbonic acid yields its carbon, reduced water its hydrogen, and in which also reduced oxide of ammonium and nitric acid yield their ammonium or their azote. If animals then continually produce carbonic acid, water, azote,...
Страница 112 - ... will soon be full of the hot air, or smoke from the fire circulating in it, and rendering it every where of as uniform temperature as if it were full of hot water.
Страница 93 - ... fire in this room were fruitless. I could not imagine the reason; till at length, observing that the chamber over it, which had no fire-place in it, was always filled with smoke when a fire was kindled below, and that the smoke came through the cracks and crevices of the...
Страница 132 - ... where it receives a fresh amount of heat, and being thus rendered lighter, rises up the pipe, b, and descends the inclined planes of the pipes, losing a portion of its heat on the way, and at the same time increasing in density ; the velocity of the current depending on the difference between the temperature of the water in the boiler, and that in the descending pipe. At the highest point of the apparatus is a pipe, i, furnished with a stop-cock for the escape of the air which the cold water...
Страница 143 - ... will heat 222 cubic feet of air 1° per minute, when the difference between the temperature of the pipe and the air is 125°.
Страница 102 - ... in various graceful architectural mouldings; sometimes surmounted with classic figures of great beauty, and opening with brass doors, kept as bright as if they were of gold. In houses of less display, these stoves are merely a projection in the wall, coloured and corniced in the same style as the apartment. In adjoining rooms they are generally placed back to back, so that the same fire suffices for both. These are heated but once in the twenty-four hours, by an old Caliban, whose business during...
Страница 110 - ... them. This heated air cannot get up the vent, because the passage above these spaces are shut up. It therefore comes out into the room ; some of it goes into the real fire-place, and is carried up the vent, and the rest rises to the ceiling, and is diffused over the room. The heating effect of this stove-grate is remarkable. Less than a quarter of the fuel consumed in an ordinary fire-place is sufficient, and this, with the same cheerful blazing hearth, and the salutary renewal of the air. Indeed,...
Страница 52 - ... watch, and then seated himself before it. He now marked precisely the hour, and lighted a brazier of charcoal beside him. He continued to note down the series of sensations he then experienced in succession, detailing the approach and the rapid progress of delirium, until, as time went on, the writing .; became confused and illegible, and the young victim dropped dead upon the floor...
Страница 189 - B consists partly of the air compressed by the extremities of the wings, and of the air rarified on its entrance near their roots. In the fan here represented, called the excentric, the air which escapes through the outlet B has undergone compression during its whole progress through the spiral space with the revolving wings, and is equal in density to that compressed at their extremities by the centrifugal force. This fan discharges therefore considerably more air than that with a chamber concentric...
Страница 50 - A large jar, called a kourcy, is sunk in the earthern floor, generally in the middle of the room. This is filled with wood, dung, or other combustible ; and when it is sufficiently charred, the mouth of the vessel is shut in with a square wooden frame, shaped like a low table, and the whole is then covered with a thick wadded quilt, under which the family, ranged around, place their knees to allow the hot vapour to insinuate itself into the folds of their clothing ; or when they desire more warmth,...
