MEDICAL ASSOCIATIONS.

American Medical Association.

Organized in New York City, May 5, 1846, as the National Medical Convention. Reorganized, and name changed, May 5, 1847. First Annual Meeting held at Baltimore, May 2, 1848.

Composed of permanent members and delegates. Each local medical society in good standing may send one delegate for every ten of its resident members, and one for every additional fraction of more than half this number. The faculty of every regularly constituted medical college, or chartered school of medicine, and the professional staff of every chartered or municipal hospital, containing one hundred inmates or more, are privileged to send two delegates; but every other permanently organized medical institution in good standing is limited in its representation to one delegate. The medical departments of the United States army and navy, are each entitled to four delegates, appointed by the chiefs of their respective bureaus. Each delegate holds his appointment for one year.

Permanent members, who are entitled to all the privileges of the Association, except voting, comprise all those who have served in the capacity of delegates, and such other members as may have been elected by unanimous vote.

Meetings are held annually on the first Tuesday in May or June, the time and place being determined by vote.

The annual dues are five dollars, to be paid before taking a seat as delegate.

Permanent Secretary-William B. Atkinson, M.D., 1400 Pine Street, S. W. cor. Broad Street, Philadelphia, Pa.
