Стр. 21 - Hear, Nature, hear ! dear goddess, hear ! Suspend thy purpose, if thou didst intend To make this creature fruitful ! Into her womb convey sterility ! Dry up in her the organs of increase, And from her derogate body never spring A babe to honour her ! If she must teem...
Стр. 22 - I have ventured, Like little wanton boys that swim on bladders, This many summers in a sea of glory ; But far beyond my depth ; my high-blown pride At length broke under me ; and now has left me, Weary, and old with service, to the mercy Of a rude stream, that must for ever hide me.
Стр. 22 - 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.
Стр. 179 - To me the fundamental supposition itself seems impossible, namely, that the waves or vibrations of any fluid can, like the rays of light, be propagated in straight lines, without a continual and very extravagant spreading and bending every way into the quiescent medium, where they are terminated by it.
Стр. 19 - Pr'ythee, lead me in: There take an inventory of all I have, To the last penny ; 'tis the king's : my robe, And my integrity to heaven, is all I dare now call mine own.
Стр. 119 - He seldom gave an opinion, and never volunteered one. He never laid down the law like other learned Doctors, or uttered apothegms, or sayings to be remembered. Indeed, like most mathematicians, (though we hear of abstract mathematics,) he never seemed to think abstractedly. A philosophical fact, a difficult calculation, an ingenious instrument, or a new invention, would engage his attention ; but he never spoke of morals, of metapHysics, or of religion.
Стр. 142 - Suppose a number of equal waves of water to move upon the surface of a stagnant lake, with a certain constant velocity, and to enter a narrow channel leading out of the lake ; suppose, then, another similar cause to have excited another equal series of waves, which arrive at the same channel with the same velocity and at the same time with the first. Neither series of waves will destroy the other, but their effects will be combined : if they enter the channel in such a manner that...
Стр. 116 - When the master introduced Young to his tutors, he jocularly said, ' I have brought you a pupil qualified to read lectures to his tutors.' This, however, as might be concluded, he did not attempt : and the forbearance was mutual ; he was never required to attend the common duties of the college.
Стр. 183 - ... Boyle, and Cavendish, and Maskelyne, and Herschel. Young's most famous experiment of stopping the rays which passed on one side of a thin card exposed to a sunbeam in a dark chamber Brougham threw aside, with the assertion that the experiment was inaccurately made. Dr. Young replied : The reviewer has here afforded me an opportunity for a triumph, as gratifying as any triumph can be where an enemy is so contemptible. Conscious of inability to explain the experiment, too ungenerous to confess...
Стр. 116 - Person, he said that if he had seen it before he would have adopted it. The views, objects, character, and arguments of our mathematicians were very different then to what they are now, and Young, who was certainly beforehand with the world, perceived their defects. Certain it is that he looked down upon the science, and would not cultivate the acquaintance of any of our philosophers. Wood's books I have heard him speak of with approbation, but Vince he treated with contempt, and Vince afterwards...
