IV.-CHEMISTRY, 



INTRODUCTORY NAERAT1VE. 

 LESSON I. 



RATHER more than seventy-three 

 years ago, there resided in the old 

 corporate town of Penzancc which is 

 situated on the north-western shore of 

 Mount's Bay, in Cornwall a carver in 

 wood, who has left some specimens 

 behind him in the town, to testify that 

 he was a skilful workman. On the 

 17th December, 1778, his family was 

 increased by the addition of a fine boy, 

 whose name was afterwards intimately 

 connected with Chemistry, and will 

 ever #race the calendar of science- 

 Sir Humphry Davy.
