392 LIFE OF BENJAMIN SILLIMAN. 



February 19." The course of lectures on Natural Re- 

 ligion, in the Odeon, by the Rev. Dr. Walker of Harvard 

 College, on the Lowell foundation, was to be finished the 

 evening of our arrival, and we availed ourselves of the op-

 distinctive features and boundaries and connections of 

 each, coming down finally to the one science chemistry 

 which was to engage our immediate attention. This 

 lecture was read, quite audibly, I believe, to an audience 

 estimated to amount to fifteen hundred persons or more. 

 They were very attentive, and perfectly quiet during the 

 hour and a quarter which the discourse occupied. I 

 was glad to have got well through this lecture, the 

 only one in the course which I expected to read, which 

 I very much dislike to do, as in reading my manner is 

 artificial, and lacks the genial tone and expression which 

 an earnest speaker, full of his subject, and looking his 

 audience in the face, naturally assumes. I had, how-
