ProvenanceOwned and used by Professor Jeffries Wyman, Professor of Anatomy and Curator of the Peabody Museum at Harvard University. Given by Mary M. Wyman, daughter of Dr. Jeffries Wyman, to Professor Alpheus Hyatt for the Boston Society of Natural History in October 1899. Presented by Prof. Alpheus Hyatt, Oct. 6, 1900, to Dr. Ernst. Part of Ernst-Lewis Collection of Microscopes (inv. no. 16), Harvard Medical School, 1900.
Historical AttributesThe Tolles notebook (p. 21) describes a No. 2 side illuminator made for Mr. Twitchell on September 24, 1869. Since this one is dated February 23, 1867, perhaps it is No. 1.
