Letter to Harvey Cushing from F.X. Dercum, 1719, Walnut Street, Philadelphia, Pennsylvania, USA. The founders of the American Anthropometric Society were Dr. Harrison Allen, Dr. Joseph Leidy, Dr. William Pepper, Dr. Edward Spitzka and Dr. Dercum. The first meeting was held in 1899 and Osler was a member. The brains collected by the Society were kept in the Wistar Institute and studied by Dr. Spitzka. His findings were published in the Transactions of the American Philosophical Society, N.S., Volume XXI, Part III. [See CUS417/78.21] Incl. ms. notes.
