Pàgina 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...
Pàgina 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.
Pàgina 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.
Pàgina 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.
Pàgina 486 - SCIENCE, FIRST ESTABLISHED THE UNDULATORY THEORY OF LIGHT, AND FIRST PENETRATED THE OBSCURITY WHICH HAD VEILED FOR AGES THE HIEROGLYPHICS OF EGYPT. ENDEARED TO HIS FRIENDS BY HIS DOMESTIC VIRTUES, HONOURED BY THE WORLD FOR HIS UNRIVALLED ACQUIREMENTS, HE DIED IN THE HOPES OF THE RESURRECTION OF THE JUST.
Pàgina 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...
Pàgina 119 - 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.
Pàgina 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.
Pàgina 317 - 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,...
Pàgina 140 - Pression or Motion cannot be propagated in a fluid in right lines beyond an obstacle which stops part of the Motion, but will bend and spread every way into the quiescent Medium which lies beyond the Obstacle.
