Seite 910 - ... 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 the winter...
Seite 748 - Daniell, who has stated to us that from the results of experiments, he is of opinion ' the nearer the magnesian limestones approach to equivalent proportions of carbonate of lime and carbonate of magnesia, the more crystalline and better they are in every respect.* 1 657.
Seite 742 - ... instead of employing given weights adapted to the lines of least resistance. The line of least resistance is that line by which the explosion of the powder will find the least opposition to its vent in the air. This need not necessarily be the shortest line to the surface; as, for instance, a long line in earth may, from the same charge, afford less resistance than a shorter line in rock. Supposing the matter in which the explosion is to take place to be of uniform consistence in every direction,...
Seite 926 - ETC. 179 in evidence given before the Health of Towns Commission, and in other published documents, both an extraordinary reduction of the number of sick applying for relief, and of the severity of diseases occurring.* Wide experience elsewhere has since obtained similar results. Most of the hospitals and poor-houses in the kingdom now have these chimney-valves ; and most of the medical men and others who have published of late on sanitary matters, have strongly commended them.
Seite 695 - An engine so contrived, that working the primum mobile forward or backward, upward or downward, circularly or cornerwise, to and fro, straight, upright, or downright, yet the pretended operation continueth, and advanceth, none of the motions above-mentioned hindering, much less stopping the other; bnt unanimously, and with harmony agreeing, they all augment and contribute strength unto the intended work and operation. And therefore I call this...
Seite 910 - Within these great houses, not a breath of cold is experienced. The rooms are heated by stoves, frequently ornamental rather than otherwise ; being built in tower-like shapes, story over story, of pure white porcelain, 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...
Seite 791 - Ireland from the establishment of the manufacture of sugar from the beet-root ; and, it appears to me as eminently calculated to be of service, not only as creating a new and extensive source of manufacturing employment, but, also, that, as the material used can only be profitably obtained by means of improved agriculture, and that an important element in the profits of the manufacture would be the careful economy of the scums and pulp...
Seite 696 - ... to keep them sweet, running through several streets, and so performing the work of scavengers, as well as furnishing the inhabitants with sufficient water for their private occasions ; but likewise supplying...
Seite 820 - To see how the action of caffeine, asparagine, theobromine, &c. may be explained, we must call to mind that the chief constituent of the bile contains only 3'8 per cent, of nitrogen, of which only the half, or 1-9 per cent., belongs to the taurine. Bile contains in its natural state water and solid matter, in the proportion of 90 parts by weight of the former to 10 of the latter. If we suppose these 10 parts by weight of solid matter to be choleic acid, with 3-87 per cent, of nitrogen, then 100 parts...
Seite 885 - ... a stack of the same conical shape, are let into this cavity. The whole is then covered with turf, to prevent the volatile parts from being dissipated, which, by means of a heavy wooden mallet, and a wooden stamper worked separately by two men, is beaten...
