than thirty papers, published separately in advance by Professor Cope as "Paleontological Bulletins," were included in the official reports of the Government geological surveys of the Territories as special reports of the departments of the work which were assigned to him, including general geology, and the identification, classification, and descriptions of new fossils and species. Among papers which do not fall exactly under any of these heads may be mentioned those "On the Fresh-Water Origin of Certain Deposits in West New Jersey"; "The Birds of Palestine and Panama compared"; "On some New and Little known Myriapoda from the Southern Alleghanies"; "Intelligence in Monkeys"; "The Significance of Paleontology"; "Biological Research in the United States"; articles on "Osteology" and "Comparative Anatomy" in Johnson's "Cyclopædia"; "Excursions of the Geological Society of France"; "The Fauna of the Lowest Tertiary of France"; "A New Deer from Indiana"; "The Modern Museum"; "Pliocene Man," etc. His papers on evolution form a separate department. Professor Cope has been a diligent student of this subject, and has opinions of his own upon it. Among his principal contributions to its literature are: "On the Origin of Genera" (1868); "Method of Creation of Organic Types" (1871); "Evolution and its Consequences" (1872); "Homologies and Origin of the Molar Teeth of Mammalia Educabilia" (1874); "Consciousness in Evolution" (1875); "Relation of Man to Tertiary Mammalia" (1875); "On the Theory of Evolution" (1876); "The Origin of the Will" (1877); "The Relation of Animal Motion to Animal Evolution" (1878); and "A Review of the Modern Doctrine of Evolution" (1879).
Professor Cope was for a long time Secretary and Curator of the Academy of Natural Sciences, of Philadelphia, and was chief of the Department of Organic Material of the Permanent Exposition of that city. He received the Bigsby gold medal of the Royal Geological Society of Great Britain in 1879; is a member of the Geological Society of France, and of the American Association for the Advancement of Science.
