In addition to articles of theoretical interest, the Papers will welcome des- criptive studies putting factual information on record, as well as bibliographies, linguistic texts, vocabularies and historical docu- ments of anthropological interest. The Society welcomes student research papers of high quality. Manuscripts must be typewritten, double spaced, on good quality 8-1/2 x 11 inch paper, and on one side of the page only. Endnotes (the Papers do not employ footnotes) and bibliography should be placed on separate sheets. The bibliographic style to be followed is that used in this number of the Papers. Authors will note that the bibliographic style is an extended version of that employed by the American Anthro2ologist. A style sheet containing further information concerning manuscripts and bibliographic style may be obtained from the Society upon request. Authors will receive without charge twenty reprints of their articles. Additional reprints may be ordered at the price of one cent per page. A small extra charge will be made if illustra- tions must be reproduced by photolithography. When notified of the acceptance of their manuscripts, authors will be asked how many additional reprints they desire.
