most remarkable works in the whole field of biological literature. Another memoir gives the results of his study of the anatomy of snails and slugs. The inhabitants of the streams and ponds in the vicinity of his home furnished an unfailing supply of material for research and discovery, and many of his publications are on aquatic animals. He finally became so much interested in the fresh-water rhizopods that he abandoned all other scientific work in order to devote all his attention to these animals. His results were published in the memoir on The Fresh-water Rhizopods of North America. This is the most widely known of his works. It is, and must long be, the standard and classic upon its subject. I have no time to dwell upon his work as the naturalist of the home—his best and most characteristic work. Its lesson to later generations of naturalists seems to me to be that one may be useful to his fellowmen, and enjoy the keen pleasure of discovery, and come to honor and distinction, without visiting strange countries in search of rarities, without biological stations and marine laboratories, without the latest technical methods, without grants of money, and, above all, without undertaking to solve the riddles of the universe or resolving biology into physics and chemistry.
If one have the simple responsive mind of a child or of Leidy, he may, like Leidy, 'find tongues in trees, books in the running brooks, sermons in stones, and good in everything.'

By Professor HENRY FAIRFIELD OSBORN
In the beautiful marble portrait of Edward Drinker Cope, modeled by Mr. Couper and presented by President Jesup, you see the man of large brain, of keen eye, and of strong resolve, the ideal combination for a life of science, the man who scorns obstacles, who while battling with the present looks above and beyond. The portrait stands in its niche as a tribute to a great leader and founder of American paleontology, as an inspiration to young Americans. In unison with the other portraits its forcible words are: 'Go thou and do likewise.'
Cope, a Philadelphian, born July 28, 1840, passed away at the early age of fifty-seven. Favored by heredity, through distinguished ancestry of Pennsylvania quakers, who bequeathed intellectual keenness and a constructive spirit. As a boy of eight entering a life of travel and observation, and with rare precocity giving promise of the finest qualities of his manhood. Of incessant activity of mind and
