140 LIFE OF BENJAMIN SILLIMAN. 



researches. The morning after the lecture, Mr. Dalton 

 gave me an hour or two in a conversational explanation of 

 his views, and in showing me his apparatus and mode of 

 experimenting. I had, in after years, occasion often to

 his name, as well as that of his (then to him unknown) co-

 to me. I was, however, willing to look at the subject and 

 see what could be done. The orders Avhich were com- 

 mitted to me for the purchase of books and apparatus re- 

 quired a residence in London during the summer ; and I 

 was desirous to discover what sources of information were 

 accessible in the metropolis. My first object was, however, 

 to make arrangements for obtaining the books for the 

 library, and the apparatus for the philosophical and chemical
