          When you see Dr. Alonso Clark, will you, 
 with my compliments, remind him that I have 
 never received back again the pamphlet on the 
 Microscope by Ross, which belongs to the Lowell 
 Microscope, and which he was to return from 
 Boston. 


 Lyell has done better than before but is not in 
 my mind a good lecturer at all. He has had a
 fine audience throughout. They have been so much 
 interested in his later lectures occupying, tho' under
 a rather different aspect the ground I am to take
 up in my four last lectures on Geographical Botany 
 &c., that I feel quite emboldened to go on with 
 them. I am sure I can present the subject more 
 clearly and intelligibly, for Lyell jumbles much. 
 He finishes this evening, and I believe goes South. 
 I see him & Mrs. Lyell now and then, chiefly at 
 the Lecture room. 


 By the steamer I had nothing to speak of except 
 a nice letter from Joe Hooker, which had much 
 intelligence that you will be interested in. I enclosed
 it in a letter to Eliza. If you do not go home
 to-morrow, they will send it to you from Princeton. 


 I send you here with the proceedings of the Town 
 Council of Edinbro [Edinburgh], on the election of the Professor, 
 in the newspaper part of the last Gardener's Chronicle. 
 Be sure to send it back again, not to break my 
 set. Arnott, you will hear of in Hooker's letter,
