The appropriation amounted to about $650.000—about $467,000 being for the maintenance of its departments; $50,000 for minor grants; $30,000 for research associates and assistants; $54,000 for publication, and $50,000 for administrative expenses. As indicated in the last issue of the Monthly, the administration building was dedicated in November. No new department was inaugurated during the year, but the observatory for meridian astronomy at San Luis, Argentina, began its work under the direction of Dr. Louis Boss, of the Dudley Observatory, Albany.

All the leading officers of the institution were engaged in scientific work before its establishment, and it is a question whether their work is better than it would have been if they had remained in their previous positions. The places which they held have been filled by others and there is
