Side 120 - ... to dive into the depths of dungeons; to plunge into the infection of hospitals; to survey the mansions of sorrow and pain; to take the gauge and dimensions of misery, depression, and contempt; to remember the forgotten, to attend to the neglected, to visit the forsaken, and to compare and collate the distresses of all men in all countries.
Side 30 - In thoughts from the visions of the night, When deep sleep falleth on men, Fear came upon me, and trembling, Which made all my bones to shake. Then a spirit passed before my face; The hair of my flesh stood up...
Side 262 - In its sublime research, philosophy May measure out the ocean deep, may count The sands or the sun's rays : but, God, for thee There is no weight nor measure ; none can mount Up to thy mysteries.

Side 182 - Pope had only a little, because Dryden had more : for every other writer since Milton must give place to Pope ; and even of Dryden it must be said, that, if he has brighter paragraphs, he has not better poems.
Side 182 - For this reason he kept his pieces very long in his hands, while he considered and reconsidered them. The only poems which can be supposed to have been written with such regard to the times as might hasten their publication, were the two satires of ' Thirty- eight ; ' of which Dodsley told me, that they were brought to him by the author, that they might be fairly copied.
