Page 135 - AN INTRODUCTION TO THE STUDY OF CHEMICAL PHILOSOPHY : being a preparatory View of the Forces which concur to the Production of Chemical Phenomena. By J. FREDERIC DANIELL, FRS Professor of Chemistry in King's College, London ; and Lecturer on Chemistry and Geology in the Hon. East India Company's Military Seminary at Addiscombe ; and Author of Meteorological Essays.
Page 28 - SOUND : a Course of Eight Lectures delivered at the Royal Institution of Great Britain. By JOHN TYNDALL, LL.DFRS New Edition, crown 8vo.
Page 19 - ... appeared precisely similar to the spectra of those nebulae of which the light is apparently monochromatic. This resemblance was made more complete by the faintness of the line ; from which cause it appeared much narrower, and the separate existence of its two components could no longer be detected. When this line was observed simultaneously with that in the nebula, it was found to appear but a very little broader than that line.
Page 19 - It is obvious that if the spectrum of hydrogen were reduced in intensity, the line in the blue, which corresponds to that in the nebula, would remain visible after the line in the red and the lines more refrangible than F had become too feeble to affect the eye. " ' It therefore becomes a question of much interest whether the one, two...
Page 12 - Heat is a very brisk agitation of the insensible parts of the object, which produces in us that sensation from whence we denominate the object hot ; so what in our sensation, is heat, in the object is nothing but motion.
Page 233 - THE minutes of the previous meeting having been read and confirmed, the President referred to the intimation that Mr.
Page 96 - The colouring-matter is in fact a natural organic compound of which copper is one of the essential constituents. Traces of this metal had previously been found in animals, for example, in oysters, to the cost of those who partook of them. But in these cases the presence of the copper was merely accidental ; thus oysters that lived near the mouths of streams which came down from copper-mines assimilated a portion of the copper salt, without apparently its doing them either good or harm.
Page 97 - No other physical science has been brought to such perfection as mechanics; and In mechanics we have long been familiar with the Idea of the perfect generality of its laws, of their applicability to bodies organic as well as Inorganic, living as well as dead. Thus in a railway collision, when a train is suddenly arrested the passengers are thrown forward, by virtue of the Inertia of their bodies, precisely according to the laws which regulate the motion of dead matter. So trite has the idea become...
Page 235 - No explanation is wrung from her; no present won from her, which she does not give freely. She is cunning, but for good ends, and it is best not to notice her tricks. 'She is complete, but never finished. As she works now, so can she always work. Everyone sees her in his own fashion. She hides under a thousand names and phrases, and is always the same.
Page 97 - Universe (p. 184) :'Admitting to the full as highly probable, though not completely demonstrated, the applicability to living beings of the laws which have been ascertained with reference to dead matter, I feel constrained at the same time to admit the existence of a mysterious something lying beyond, a something...
