Dr. Koch at this meeting offered to visit Mississippi for the academy, and investigate certain finds recently made of the remains of Zeuglodon—a gigantic fossil whale. This was probably the first investigation made at the expense of the new academy. Dr. Koch visited Mississippi,

Among the original members was Mr. Charles P. Chouteau, one of two out of that list of incorporators who still lives. Mr. Chouteau, a man of business and means, never permitted his intelligent interest in the academy and its work to flag. Connected with the fur trade, his business took him or his representatives on frequent journeys into the far West. Such expeditions were enormous enterprises in those days. At that time even journeys to the East were no trifles. Mr. Chouteau—after recently making the trip from St. Louis to New York in twenty-four hours—narrates that on one occasion, when a young man, he was sent to New York to see Mr. Astor on im-
