had copied in colors an illustration of Owen’s so-called arche- 
type reproduced in Carpenter’s Physiology. Subsequently, 
however, the fact that there was only an approximation to the 
realization of it in the most specialized of fishes and not at all 
among the lower or higher vertebrate, with other considera- 
tions, turned me from it, and I gave my reasons for dissent to 
Cope. Ultimately he admitted the force of the argument, and 
also abandoned the theory at one time so popular in England 
and America. 
Our acquaintance, thus begun in 1859, continued uninter- 
ruptedly till death divided us. We rarely met, indeed, that 
we did not express difference of opinion respecting some sub- 
ject, but the difference was never of a serious nature, and gen- 
erally little more than sufficient to enliven intercourse.

_ The future naturalist was born in Philadelphia on the 28th 
of July, 1840, and the name Edward Drinker was given to him. 
He was the descendant of a prosperous line long established in 
Pennsylvania. His father, Alfred was a man of cultivated 
literary taste, and did much to train his son’s mind in early 
youth. He had retired from active business and lived in 
luxurious ease near Germantown,’ a suburb of Philadelphia. 
There he had formed an arboretum containing most of the 
American trees which would thrive in the climate of that re- 
gion. Amidst such surroundings the youthful Cope grew up. 
An active and intelligent interest in Nature became mani- 
fest at a very early age. When only about seven years old, 
during a sea voyage to Boston with his father, the boy is said 
to have kept a journal which he filled with drawings of “ jelly 
fish, grampuses and other natural objects seen by the way.” 
*I am indebted to a brother in-law of Prof. Cope, Mr. Philip C. Garrett, for 
fuller information and rectifications of statements made in the original address, 
which I have utilized in this edition in the form of notes. 
_* According to Mr. Garrett, “ in strict accuracy, his father either had not re- 
tired from active business or had never been in it, having been and remaining 
What is called an active partner of H. & A. Cope, though, it must be admitted, a 
rather inactive one at all times through very poor health. The home in which 
Edward was reared from early boyhood was not in Germantown, but about a mile 
east of it on the York road.”
