340 LIFE OF BENJAMIN SILLIMAN. 



cially attracted to his lectures the refined and cultiva 

 ted. The numerous courses which he gave in all parts 

 of the land were almost uniformly successful. He 

 kindled wherever he went a lively interest in the

 assistance to my family at a period when my children were 

 requiring aid in their settlement in life. I conceive that 

 in no period of my life have my efforts been more useful, 

 both to my country and my family ; and' as regards pro

 1834, was the first that I delivered out of New Haven.

 Smith and Daniel Wadsworth, Esqrs. Their letter, dated
