Pagina 116 - ... might acquire — and yet weak enough to give way slowly to a continued force. When at last the tables, cards, and hands all moved to the left together, and so a true result was obtained, I took up the pack. On examination, it was easy to see by the displacement of the parts of the line, that the hand had moved further than the table, and that the latter had lagged behind — that the hand, in fact, had pushed the upper card to the left, and that the under cards and the table had followed and...
Pagina 117 - The result was, that when the parties saw the index, it remained very steady ; when it was hidden from them, or they looked away from it, it wavered about, though they believed that they always pressed directly downwards ; and when the table did not move, there was still a resultant of hand force in the direction in which it was wished the table should move, which, however, was exercised quite unwittingly by the party operating. This resultant it is which, in the course of the waiting time, while...
Pagina 196 - A Verb Passive expresses a passion or a suffering, or the receiving of an action ; and necessarily implies an object acted upon, and an agent by which it is acted upon : as, to be loved ;
Pagina 266 - Chloride of sodium 6'906 9-420 The mould around the plants and an infusion of the dead stems and leaves also afforded abundant evidence of the presence of much chloride of sodium. Further inquiry showed that the well from which the water was procured had an accidental communication, by means of a drain, with the sea ; and had thus become mixed with the salt water from that source, and had been used in this state for some weeks, probably from two to three months.
Pagina 250 - From these it appeared that distilled water to which a known quantity of ammonia had been added, furnished more ammonia than had been mixed with it ; so that, apparently, all distilled water contains ammonia. The water employed in the following experiments was distilled first with sulphate of alumina, and afterwards over potash, to remove any ammonia and carbonic acid that might be contained in it. In the following table the first column gives the number of the experiment, the second the quantity...
Pagina 347 - I have never seen anything like the splendor of a Persian summer evening. It is not too much to say, that, were it not for the interference of the moon we should have seventy-five nights in the three summer months, superior for purposes of observation to the very finest nights which favor the astronomer in the New World.
Pagina 115 - Then, the table turner placed the hands upon the upper card, and we waited for the result. Now, the cement was strong enough to offer considerable resistance to mechanical motion, and also to retain the cards in any new position which they might acquire — and yet weak enough to give way slowly to a continued force. When at last the tables, cards, and hands all moved to the left together, and so a true result was obtained, I took up the pack. On examination, it was easy to see by the displacement...
Pagina 16 - It consists of two parts, of one and two stories respectively, and occupies the entire space between the main building and the Reservoir. Its length is 451 feet and 5 inches, and its extreme width is 75 feet. It is designed for the reception of machinery in motion, the cabinets of mining and mineralogy, and the refreshment rooms with their necessary offices. The second story, which is 21 feet wide, and extends the whole length, is entirely devoted to the exhibition of pictures and statuary.
