Abstract :
NOTICE TO AUTHORS — The Meetings and Papers Committee announces that papers intended for the 1924 Midwinter Convention must be received prior to October 12, 1923. Manuscripts received after this date will be considered only for subsequent meetings. In order to review, edit, print, and mail copies of more than a score of papers in advance of the conventions, three months are required. Much advanced engineering work is being done this year. A considerable part of the Midwinter Convention program is already made up of papers crowded out of the Swampscott Convention. Members preparing papers for any of the four conventions of 1924 are requested to send a preliminary note of the approximate title and probable date of completion to the Meetings and Papers Committee.
