Page 227 - twere anew, the gaps of centuries ; Leaving that beautiful which still was so, And making that which was not, till the place Became religion, and the heart ran o'er With silent worship of the great of old ! — The dead, but sceptred sovereigns, who still rule Our spirits from their urns.

Page 250 - Before having any knowledge of the method given in the above account, I had succeeded in producing electrical effects in the following manner, which differs from that employed by Mr. Faraday, and which appears to me to develop some new and interesting facts. A piece of copper wire, about thirty feet long and covered with elastic varnish, was closely coiled around the middle of the soft iron armature of the galvanic magnet described in Vol.
Page 202 - We get no good By being ungenerous, even to a book, And calculating profits . . so much help By so much reading. It is rather when We gloriously forget ourselves, and plunge Soul-forward, headlong, into a book's profound, Impassioned for its beauty and salt of truth — 'Tis then we get the right good from a book.
Page 112 - July, 1862; which is to be set apart as a sinking fund; and the interest of which shall in like manner be applied to the purchase or payment of the public debt, as the Secretary of the Treasury shall from time to time direct.
Page 253 - The effect appears somewhat increased by coiling the wire into a helix ; it seems also to depend in some measure on the length and thickness of the wire. I can account for these phenomena only by supposing the long wire to become charged with electricity which by its reaction on itself projects a spark when the connection is broken...
Page 239 - Ibs., or more than 50 times its own weight These experiments conclusively proved that a great development of magnetism could be effected by a very small galvanic element, and also that the power of the coil was materially increased by multiplying the number of wires, without increasing the length of each.
