=Thomas Henry Huxley (1825-1895)=, one of the greatest of our men of science, was of interest not only on account of his vast scientific attainments, but for his profound acquaintance with metaphysics, as illustrated in his "Life of Hume," his wide culture, and his exquisite literary style. He was born and educated at Ealing, in Middlesex, where his father was a schoolmaster. He studied medicine at the Charing Cross Hospital, then entered the Royal Navy as an assistant surgeon, and went in the _Rattlesnake_ to survey the Barrier Reef of Australia. The papers which he sent to the Royal and Linnæan Societies gave him fame. After his return he devoted himself to original research; but work of that sort brings no recompense in money, and Huxley's means were narrow. In 1854, however, he obtained the chairs of Natural History and Palæontology at the School of Mines, and to this he afterwards added the appointment of Inspector of Fisheries. The "blue ribbon" of science, the Presidency of the Royal Society, was conferred on him in 1883. Huxley wrote much on biological problems, and by the publication of his "Physiography" gave a new name to the science which has extended the scope of the old Physical Geography: but his chief interest for us here is in his "Lay Sermons," "Addresses and Reviews," his "Critiques and Addresses," and his "American Addresses," all of which may take rank among the finest prose of our age. As an interesting contrast to the work of Darwin and Huxley, and all that it has implied to modern literature, one may refer once again to the movement inspired by Cardinal Newman. His most prominent associates for many years, neither of whom, however, left the Church of England for the Church of Rome, were Pusey and Keble.
