PUBLICATIONS. THE publications of the Institute comprise : 1. The minutes of the Proceedings of each Meeting, published in pamphlet form. 2. Such of the papers presented or read by title at each Meeting as are furnished by the authors and approved by the Council for full publication. (In nearly all cases in which papers, the titles of which appear in the Proceedings, are not subsequently published, they have been withdrawn by the authors.) These papers are published separately in pamphlet form, and are marked "Subject to Revision." A small supply, beyond the edition distributed, is retained to meet subsequent demand. There are no copies on hand of papers read before 1880. The stock is nearly complete from 1880. 3. Annual volumes of Transactions, containing the list of officers, rules, etc.; the Proceedings; and the papers, revised for final publication. (In this revision after the preliminary publication, authors are permitted to use the largest liberty; and the changes and additions made in papers are sometimes important. It should be borne in mind, by those who study or quote a paper in the preliminary edition, that they may not have in that form the ultimate and deliberate expression of the author's views. It should be added, however, that in the majority of cases there is no essential change, the correction of typographical errors and additions of later information being the usual alterations.) 4. Special editions of separate papers, for which there is demand. These are fully revised, and are usually issued in pamphlet covers. 5. Books. (Under this head the only publications are an Index to Vols. I.to XV. inclusive, a Glossary of Mining and Metallurgical Terms, and a Memorial of Alexander Lyman Holley.) All the foregoing publications are sent free to members and associates · not in arrears at the time of publication. They are also for sale at the office of the Secretary, or are sent to purchasers by mail or express, charges paid, on receipt of the price by the Secretary, as follows: Classes 1 and 2, above mentioned, at the following rates: NO.

Extra copies, when ordered before the types have been distributed, are furnished to authors under Rule VII., at the following rates: When a paper contains one or more separate plates or "folders," these will be charged in reprinting as follows: One page or one fold, the same as four pages in the above table; each additional fold, the same as four additional pages.
