166 LIFE OF BENJAMIN SILLIMAN. 



with his apparatus and experiments, and with the opera- 

 tions of his great mind ; and as my conversation regarding 

 Lavoisier was only eleven and a half years after his death,

 consumption, and died not many years after I left Edin- 

 burgh. He wrote to me a year or two after my return, and 

 informed me that he was about going to the south of Eng- 

 land to revive his health. A son who bore his name, re-
