Historical AttributesNote from Dr. Lewis: "Presented by Professor Alpheus Hyatt on October 16, 1900--previously the property of Professor Jeffries Wyman," who was the Hersey Professor of Anatomy from 1847 to 1874.
Curatorial RemarksResembles in particular a Nachet of 1843 shown in Collection Nachet, plate XII, p. 86, item 86 (CHSI Lib. 582).
A signed Nachet instrument (1106a) has the same wooden objective box as CHSI 1081, which is unsigned but also likely by Nachet.
