It gives us a glimpse of the celebrities assembled within its portals. At a glance the student can obtain some idea of the subject. Such books are the true foundations of that knowledge...
Page 95 - On the Absolute Quantity of Electricity associated with the Particles or Atoms of Matter." The simplicity of Faraday's diction, and the clearness with which he describes the phenomena observed, are most remarkable, and supply a '• standard of excellence " which scientific writers may well try to imitate. The following are some of "FARADAY'S RESEARCHES." correctly, whilst limited to the use of terms which are current with a certain accepted meaning. Of this kind is the term pole, with its prefixes...
Page 133 - The articles are chiefly selected so as to afford a succession of graphic parts of English History, chronologically arranged, from the consideration that the portions of history upon which general readers delight to dwell are those which tell some story which is complete in itself, or furnish some illustration which has a separate as well as a general interest.

Page 72 - Wollaston's fourth experiment,t in which the ends of coated silver wires are immersed in a drop of sulphate of copper. By passing the electricity of the machine through such an arrangement, that end in the drop which received the electricity became coated with metallic copper. One hundred turns of the machine produced an evident effect ; two hundred turns a very sensible one. The decomposing action was, however, very feeble. Very little copper was precipitated, and no sensible trace of silver from...
Page 112 - ... wire coiled upon that cylinder, but the coils on the brass cylinder not being insulated the current passes immediately from the point of the wire which is in contact with the cylinder to the spring k.
