Сторінка 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...
Сторінка 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...

Сторінка 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...
Сторінка 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.
Сторінка 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...
Сторінка 16 - It consists of two parts, of one and two stories respectively, and occupies the entire space between the main building and the Reservoir.
