The collection is composed of notes on classical authors made by Professor Anthon. There are three bound volumes: 1) notes on Latin authors, ca. 250 leaves; 2) commentary on seven plays by Euripides, ca. 260 leaves; and 3) lecture notes, ca. 140 leaves. Each leaf is closely written in a minute but clear 19th century hand. In addition there are several short manuscripts and one letter to Joseph Green Cogswell. Also included are some printed books written by Anthon and various classical editions with his commentaries.
