 which he never recovered, but died shortly afterwards in his 

 seventy-eighth year. 



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 w r hom 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.,

 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 dis- 

 interested friendship of Mr. Tonkin, a respectable medk.al 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. 



Soon after leaving Dr. Cardew's school, Davy's father died in 1794;
