In addition to announcements of meetings and various circulars sent to members from time to time, the Society issues a single serial publication entitled THE NATIONAL GEOGRAPHIC MAGAZINE. During the first two years of the existence of the Society this serial was issued in quarterly numbers. With the beginning of the third year of the Society and the third volume of the Magazine the form of publication was changed, and the serial now appears at irregular intervals in parts or brochures (designated by pages and designed either for separate preservation or for gathering into volumes) which consist either of single memoirs or of magazine brochures made up of articles, notes, abstracts, and other geographic matter, together with the Proceedings and other administrative records of the Society.
The Magazine is mailed free to members of the Society and to exchanges. The first two volumes, as well as the separate brochures of the third and the complete volume, are sold at the prices given below by the Secretary, Mr. F. H. Newell, U. S. Geological Survey, Washington, D. C.

In the interests of exact bibliography, the Society takes cognizance of all publications issued either wholly or partly under its auspices. Each author of a memoir published in THE NATIONAL GEOGRAPHIC MAGAZINE receives 25 copies, and is authorized to order any number of additional copies at a slight advance on the cost of press-work and paper; and these separate brochures are identical with those of the regular edition issued by the Society. Contributors to the magazine brochures are authorized to order any number of copies of their contributions at a slight advance on cost of press-work and paper, provided these separates bear the original pagination and a printed reference to the serial and volume from which they are extracted; but such separates are bibliographically distinct from the brochures issued by the Society. The Magazine is not copyrighted, and articles may be reprinted freely; and a record of reprints, so far as known, is kept.
