Page 194 - The special committee reported the following resolutions, which were unanimously adopted : Resolved, That in the death of...
Page 359 - Contributions to Electricity and Magnetism. No. II. On the influence of a Spiral Conductor in increasing the intensity of Electricity from a Galvanic arrangement of a single Pair, etc.
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.

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.
Page 302 - The catalogue should begin from the year 1800. There should be a catalogue according to the names of. authors, and also a catalogue according to subjects.
