Page 94 - Egyptians, as they seemed to have used it many centuries before the Christian era. The researches of modern travellers, particularly those of Sir Gardiner Wilkinson,* proved that the brick arch was known in Egypt in the reign of Amenoiph I., 1540 years BC, and the stone arch in the time of Psamaticus II., 600 years BC "The most remarkable," says Sir Gardiner Wilkinson, " are the door-ways surrounding the tanks of Assassief, which are composed of two or more concentric semicircles of brick, as well...
Page 125 - Decomposed granite, called by miners 'pot grawen,' was extremely troublesome in mines ; it consisted principally of felspar and potash, and was the China clay (Kaolin) so much used in potteries. This substance would appear to have been formed by the decomposing action of the air, or of chemically-formed oxygen. Pyrites, which appeared to have abounded in the strata of the New Cross cutting, not only had a natural tendency to decomposition, when exposed to the action of the air, but also affected...

Page 207 - When the carriage is to go through the canal, from the engine, the air must be forced into the canal behind it ; but when it is to go the contrary way, the same engine is to draw the air out of the canal, and rarify the air before the carriage, that the atmospheric air may press into the canal behind the carriage, and drive it the contrary way.

Page 252 - dead plate' in front of .the furnace is not material, as respects combustion ; in marine boilers, it is generally not more than about 6 inches broad, which is the width of the water space, between the fire and the front of the boiler ; but in land boilers it is frequently required to be very broad, to support the brick-work, especially in those cases where the flue is carried across the front. The amount of the opening between the bars, should be about...
Page 64 - Galloway remarked, that the properties of a screw with an increasing pitch, had been slightly invested by Tredgold, in his work on the Steam Engine, so early as 1827. That author had briefly referred to the subject of screw propellers, and had given some logarithmic calculations of their properties, from which he drew the conclusion, that the true screw could not be carried beyond a single convolution, with any good effect ; whereas by a progressive increase of the pitch, the propelling effort would...
