This volume is characterized by its directness throughout. The transactions are singularly free from superfluous verbiage, and the authors, as a rule, plunge in medias res without any circumlocution. The tendency of the time is shown by the appearance of a Committee on Society History, which, a footnote informs us, is composed of those members who have held continuous membership for forty years. Although several of the papers have been printed in this Journal many of them have not been elsewhere printed. The Society will next year meet at East St. Louis and the Missouri State Medical Society will meet at St. Louis at the same time. We notice that a joint committee has been appointed to act with a similar committee from the Missouri State Society to make arrangements for one day's joint meeting.
