This name was adopted by a group of small boys, who, under the tutelage of Charles W. Johnson, curator of the Wagner Free Institute, met Saturday mornings for field trips and study in the natural sciences. It was continued some years after Johnson left for a position in the Boston Society of Natural History. Mr. Rehn's listing of members gives the following: James A. G. Rehn, Carl Fenninger, Charles T. Greene, George M. Greene, Henry L. Viereck, William Beatty, Harry Wenzel, Erich Dickey. In 1903 Viereck reported to the American Entomological Society, giving a short history, and in P. P. Calvert's papers (Coll. 634) the early insect collecting records are written on the Aristotle Society's printed map forms of Pennsylvania.
