Page 229 - 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 288 - That, so soon as the Board of Regents sh'all have selected the said site, they shall cause to be erected a suitable building, of plain and durable materials and structure, without unnecessary ornament, and of sufficient size, and with suitable rooms, or halls, for the reception and arrangement, upon a liberal scale, of objects of natural history, including a geological and mineralogical cabinet; also a chemical laboratory, a library, a gallery of art, and the necessary lecture rooms...

Page 245 - In a very early stage of electro-magnetic experiments it had been suggested that an instantaneous telegraph might be established by means of conducting wires and compasses. The details of this contrivance are so obvious, and the...
Page 343 - The man of science, says Dr. Tait, ought to go on, "honestly, patiently, diffidently, observing and storing up his observations, and carrying his reasonings unflinchingly to their legitimate conclusions, convinced that it would be treason to the majesty at once of science and of religion if he sought to help either by swerving ever so little from the straight rule of truth*.
Page 252 - 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 246 - But with the 1060 feet of copper wire (a little more than one-fifth of a mile) suspended several times across the large room of the Academy, and placed in the galvanic circuit, the same magnet sustained eight ounces: that is to say, the current from the galvanic trough produced greater magnetic effect after traversing this length of wire, than it did without it. " From this experiment it appears that the current from a galvanic trough is capable of producing greater magnetic effect on soft iron after...
