 College. He indulged in more digression than had 

 been his custom in earlier days. He took delight in

 the most of his pupils. 



The practical utility of science was always kept in

 tific truth as a means of promoting human comfort

 Prompted by his encouragement, I erected Franklin 

 Hall for the purpose of providing instruction in the
