Page 135 - Philosophers, arranged so as to form half an hour's reading for every day of the year. The student finds a taste of every quality, and a specimen of every style. Should he grow weary of one author, he can turn to another ; and if inclined to be critical, he can weigh the merits of one writer against those of his fellow. 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 97 - 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 135 - 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 65 - Two electrified bodies attract or repel each other with a force which is inversely proportional to the square of the distance that separates them.
Page 104 - In further proof of this high electric condition of the particles of matter, and the identity as to quantity of that belonging to them with that necessary for their separation.
Page 74 - 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...

The effective part of the length of the wire is therefore the variable portion which is on the wood cylinder.
Page 97 - The theory which I believe to be a true expression of the facts of electro-chemical decomposition, and which I have therefore detailed in a former series of these Researches, is so much at variance with those previously advanced, that I find the greatest difficulty in stating results, as I think, correctly, whilst limited to the use of terms which are current with a certain accepted meaning. Of this kind is the term^o/*?, with its prefixes of positive and negative, and the attached ideas of attraction...
