Стр. 6 - 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. 6 - Like little wanton boys that swim on bladders, These 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. 139 - 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. 5 - 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...
Стр. 102 - 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. 78 - 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. 275 - Young who had not only first suggested that the characters in the ring of Ptolemy were phonetic, but had determined, with one very unimportant inaccuracy, the values of four of those which were common to the name of Cleopatra, which were required to be analyzed. All the principles involved in the discovery of an alphabet of phonetic hieroglyphics were not only distinctly laid down, but fully exemplified by him ; and it only required the further identification of one or two royal names with the rings,...
Стр. 143 - ... 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. 436 - The disease proved to be an ossification of the aorta, which must have been in progress for many years, and every appearance indicated an advance of age, not brought on probably by the natural course of time, nor even by constitutional formation, but by unwearied and incessant labour of the mind from the earliest days of infancy.
Стр. 155 - We see forms of matter, differing in subtilty and mobility, bearing the names of solids, liquids, and gases ; above these are the semi-material existences, which produce the phenomena of electricity and magnetism, and either caloric or a universal ether. Higher still, perhaps, are the causes of gravitation, and the immediate agents in attractions of all kinds, which exhibit some phenomena apparently still more remote from all that is compatible with material bodies. And of these different orders...
