Page 110 - ... the angle of reflection is always equal to the angle of incidence, the image for any point can be seen only in the reflected ray prolonged.
Page xciv - Mr. Watt was an extraordinary and in many respects a wonderful man. Perhaps no individual in his age possessed so much and such varied and exact information, had read so much, or remembered what he had read so accurately and well. He had infinite quickness of apprehension, a prodigious memory, and a certain rectifying and methodising power of understanding, which extracted something precious out of all that was presented to it.
Page xcvi - I presently found that, by means of this lens, air was expelled from it very readily. Having got about three or four times as much as the bulk of my materials, I admitted water to it, and found that it was not imbibed by it. But what surprised me more than I can well express was that a candle burned in this air with a remarkably vigorous flame...
Page xciv - It is needless to say, that with those vast resources, his conversation was at all times rich and instructive in no ordinary degree ; but it was, if possible, still more pleasing than wise, and had all the charms of familiarity, with all the^ substantial treasures of knowledge. No man could be more social in his spirit, less assuming or fastidious in his manners, or more kind and indulgent towards all who approached him. He...
Page xciv - ... means of dispensing with that time and tide which wait for no man, and of sailing without that wind which defied the commands and threats of Xerxes himself. This potent commander of the elements...
Page xcvii - ... striking illustration of the truth of a remark, which I have more than once made in my philosophical writings, and which can hardly be too often repeated, as it tends greatly to encourage philosophical investigations; viz. that more is owing to what we call chance, that is, philosophically speaking, to the observation of events arising from unknown causes, than to any proper design, or pre-conceived theory in this business.
Page lvi - I do not here consider. What I call attraction may be performed by impulse, or by some other means unknown to me. I use that Word here to signify only in general any Force by which Bodies tend towards one another, whatsoever be the Cause.
Page xx - Full little knowest thou, that hast not tried, What hell it is in suing long to bide: To lose good days, that might be better spent; To waste long nights in pensive discontent; To speed to-day, to be put back to-morrow; To feed on hope, to pine with fear and sorrow; To have thy prince's grace, yet want her peers...
Page 311 - The viscid product, washed and dried over oil of vitriol in vacuo, yields hydrochlorate of acrolein as a mass of velvety crystals, which melt at 32° into a thick oil, having the odour of rancid fat. It is insoluble in water, but readily soluble in alcohol and ether, on the evaporation of which it remains as a thick oil. It is resolved by heat into acrolein and hydrochloric acid. It is not apparently altered by boiling with water, or by the action of dilute solutions of the alkalis.
Page 93 - Electrical effects are exhibited by the same bodies, when acting as masses, which produce chemical phenomena when acting by their particles ; it is not therefore improbable, that the primary cause of both may be the same...
