Dr. R. Angus Smith thus describes Dalton's mode of life while living with the family of the Rev. W. Johns, of George Street, Manchester, with whom Dalton continued to reside for twenty-six years: "He rose at about eight o'clock in the morning; if in winter, went with his lantern in his hand to his laboratory, lighted the fire, and came over to breakfast when the family had nearly done. Went to the laboratory and staid till dinner-time, coming in a hurry when it was nearly over, eating moderately, and drinking water only. Went out again and returned about five o'clock to tea, still in a hurry, when the rest were finishing. Again to his laboratory till nine o'clock, when he returned to supper, after which he and Mr. Johns smoked a pipe, and the whole family seems much to have enjoyed this time of conversation and recreation after the busy day".--_Life of J. Dalton, by William Charles Henry, M.D., F.R.S., &c._ London, 1854.--_Life of J. Dalton, by Robert Angus Smith, Ph.D., F.R.S., &c._ London, 1856. SIR HUMPHRY DAVY, BART., LL.D., P.R.S., &c., MEMBER OF THE INSTITUTE OF FRANCE, ETC. Born December 17, 1778. Died May 30, 1829. This eminent philosopher was born at Penzance, in Cornwall. As a child he was remarkably healthy and strong, displaying at the same time great mental capacity. The first school he ever attended was that of Mr. Bushell, at which reading and writing only were taught. In these rudimentary branches of education he soon made such progress, that he was removed, by the master's advice, to the grammar school kept by the Rev. Mr. Coryton. He was then only six years old. Here Davy received the elements of his education until 1793, when he went to the grammar school of Truro, conducted by the Rev. Mr. Cardew, at which place he continued for about a year. Both Davy and his family received much assistance from the disinterested friendship of Mr. Tonkin, a respectable medical practitioner at Penzance, who had adopted the mother of Davy and her sisters, under circumstances of deep distress, extending his kindness to all her family, particularly to Humphry.
