I849-5 2 -] EXCURSION TO TIMBER CREEK. 29 



Agassiz saw a great deal of Morton during his two 

 months' stay at Philadelphia, frequently visiting him, 

 for Morton was already confined almost constantly to 

 his library. I may say that after George Cuvier, 

 Morton was the only zoologist who had any influence 

 on Agassiz's mind and scientific opinions. Of course, I 

 do not refer to the glacial question, which belongs to 

 another order of studies entirely outside of pure zoology. 

 I several times enjoyed the privilege of accompanying 

 Agassiz on these visits, and was much impressed by his 

 enthusiasm. He had, at last, found a naturalist to his

 knowledge of Agassiz. He delighted in showing him 

 all the rare specimens contained in the museum, and 

 finally he succeeded in organizing an excursion into

 early spring day in March, after awaiting at Camden the 

 arrival of Agassiz, who was never an early riser, the party, 

 composed of Conrad, Agassiz, Leidy, Dr. Hallowell, 

 myself, and two of Agassiz's Cambridge students, started 

 for Timber Creek, under the guidance of Dr. Harris, a
