Page 391 - Farewell, a long farewell, to all my greatness ! This is the state of man ; to-day he puts forth The tender leaves of hope, to-morrow blossoms, And bears his blushing honours thick upon him : The third day comes a frost, a killing frost ; And,— when he thinks, good easy man, full surely His greatness is a ripening, — nips his root, And then he falls, as I do.
Page 159 - I have seen the wild stone-avalanches of the Alps, which smoke and thunder down the declivities with a vehemence almost sufficient to stun the observer. I have also seen snow-flakes descending so softly as not to hurt the fragile spangles of which they were composed ; yet to produce, from aqueous...
Page 139 - ... the particles move round their own axes, and separate from each other, penetrating in right lines through space. Temperature may be conceived to depend upon the velocities of the vibrations; increase of capacity on the motion being performed in greater space; and the diminution of temperature, during the conversion of solids into fluids or gases, may be explained on the idea of the loss of vibratory motion, in consequence of the revolution of particles round their axes, at the moment when the...
Page 139 - It seems possible to account for all the phenomena of heat, if it be supposed that in solids the particles are in a constant state of vibratory motion, the particles of the hottest bodies moving with the greatest velocity...
Page 314 - I endeavoured upon this law to construct an instrument which should measure out the electricity passing through it, and which, being interposed in the course of the current used in any particular experiment, should serve at pleasure, either as a comparative standard of effect, or as a positive measurer of this subtile agent.

Page 312 - 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 pole, with its prefixes of positive and negative, and the attached ideas of attraction...
Page 313 - I propose to distinguish these bodies by calling those anions\ which go to the anode of the decomposing body ; and those passing to the cathode, cations^ ' and when I have occasion to speak of these together, I shall call them ions.

Page 139 - ... and elastic fluids, besides the vibratory motion, which must be conceived greatest in the last, the particles have a motion round their own axes, with different velocities, the particles of elastic fluids moving with the greatest quickness : and that in ethereal substances the particles move round their own axes, and separate from each other, penetrating in right lines through space.
