4 TESTIMONIALS. 



long connexion with Princeton College as Professor of Natural 

 History, he has had an opportunity of arranging his knowledge 

 so as with ease to communicate it to others. 1 most cheerfully 

 recommend him to the friends of Education, as a teacher of great 

 learning and experience, and a gentleman of probity and excel- 

 lence of character.

 his course of Eight Lectures on Zoology to the Young Ladies

 who has himself seen what he describes. 



It apoears to me that our higher Seminaries would very much
