Wide agreement as to a clear and useful nomenclature is of great benefit in any field of science. The nomenclature here presented merits wide acceptance among terpene and other interested chemists because of the thorough way in which the careful work was done. Many versed in the chemistry of terpenes and many others experienced in naming chemical compounds were consulted. Full opportunity for criticism was offered. The proposed system of nomenclature for terpene hydro- -carbons has been accepted by the Nomenclature Committee of the American Chemical Society's Division of Organic Chemistry (Committee A) and approved by the American Chemical Society (ACS).
