Notes:
Thomas Say (1787-1834) was an American naturalist. His definitive studies of insects and shells, numerous contributions to scientific journals, and scientific expeditions to Florida, Georgia, the Rocky Mountains, Mexico, and elsewhere made him internationally known. Say has been called the father of American descriptive entomology and American conchology. He served as librarian for the Academy of Natural Sciences of Philadelphia, curator at the American Philosophical Society, and professor of natural history at the University of Pennsylvania. In 1821 he was appointed Professor of Zoology at the Peale Museum, but he evidently did not give the planned lectures.
