Notes:

The donor was probably Andrew Ellicott (1754-1820), surveyor and mathematician and Peale's fellow member of the American Philosophical Society. He may have acquired the specimen during his Pennsylvania commission in 1793-1796 to plot a road from Reading, Pa. to Presqu'Ile, Pa. and plan the city of Erie.
