Page 205 - Them hath he filled with wisdom of heart, to work all manner of work, of the engraver, and of the cunning workman, and of the embroiderer, in blue, and in purple, in scarlet, and in fine linen, and of the weaver, even of them that do any work, and of those that devise cunning work.
Page 184 - the painting and gilding of the architecture of the east end of the church, over the Communion-table, was intended only to serve the present occasion, till such time as materials could have been procured for a magnificent design of an altar, consisting of four pillars wreathed, of the richest Greek marbles, supporting a canopy hemispherical, with proper decorations of architecture and sculpture ; for which the respective drawings and a model were prepared.
Page 108 - THE forces concerned in the laying and lifting of deep submarine cables attracted much public attention in the years 1857-58. An experimental trip to the Bay of Biscay in May 1858, proved the possibility, not only of safely laying such a rope as the old Atlantic cable in very deep water, but of lifting it from the bottom without fracture. The speaker had witnessed the almost incredible feat of lifting up a considerable length of that slight and seemingly fragile thread from a depth of nearly 2J nautical...
Page 252 - I am about to discourse on ; that word is continuity, no new word, and used in no uew sense, but perhaps applied more generally than it has hitherto been. We shall see, unless I am much mistaken, that the development of observational, experimental, and even deductive knowledge is either attained by steps so extremely small as to form really a continuous ascent : or, when distinct results apparently separate from any co-ordinate phenomena have been attained, that then, by the subsequent progress of...
Page 110 - ... that can be done to find whether it is just on board or just overboard, is to cut the cable as near the outgoing part as the mechanical circumstances allow to be safely done. The electric test immediately transferred to the fresh-cut seaward end shows instantly if the line is perfect between it and the shore- A few minutes more, and the electric tests applied to the two ends of the remainder on board, will, in skilful hands, with a proper plan of working, show very closely the position of the...
Page 111 - ... sides of its grapnel, as nearly vertical as is necessary to make sure work of getting the cable on board. This plan was illustrated by lifting, by aid of two grapnels, a very fragile chain (a common brass chain in short lengths, joined by links of fine cotton thread) from the floor of the Royal Society. It was also pointed out that it can be executed by one ship alone, with only a little delay, but with scarcely any risk of failure. Thus, by first hooking the cable by a holding grapnel, and hauling...
Page 109 - ... jockey pulleys," by which the cable in entering the machine has the small amount of resistance applied to it which it requires to keep it from slipping round the main drum. The rate of egress of the cable was kept always under perfect control by a weighted friction brake of Appold's construction (which had proved its good quality in the 1858 Atlantic expedition) applied to a second drum carried on the same shaft with the main drum. When the weights were removed from the brake (which could be...
Page 82 - Taste (whatever it is) is improved exactly as we improve our judgment, by extending our knowledge, by a steady attention to our object, and by frequent exercise. They who have not taken these methods, if their Taste decides quickly, it is always uncertainly; and their quickness is owing to their presumption and rashness, and not to any sudden irradiation that in a moment dispels all darkness from their minds.
Page 111 - ... apparatus. 10. That the cable of 1865, owing to the improvements introduced into the manufacture of the gutta-percha core, . was more than one hundred times better insulated than cables made in 1858, then considered perfect and still working. 11. That the electrical testing can be conducted with such unerring accuracy as to enable the electricians to discover the existence of a fault immediately after its production or development, and very quickly to ascertain its position in the cable. 12....
Page 111 - Company, informing him that it is intended to use three ships, and to be provided both with cutting and with holding grapnels, and expressing great confidence as to the success of the attempt. In this confidence the speaker believed every practical man who witnessed the Atlantic operations of 1865 shared, as did also, to his knowledge, other engineers who were not present on that expedition, but who were well acquainted with the practice of cable-laying and mending in various seas, especially in...
