REPORT
OF THE
COMMITTEE
ON PUBLICATIONS.
To the Board of Managers: The publications of the Institute, particularly its monthly JOURNAL and the reprints of individual articles therein, have expanded in volume during the past year in natural sequence to the widening scope of scientific work that has come to be centred here. The prevailing activity in the field of analytical research, both in the collecting of purely theoretical data and also the practical application of such data in the advancement of the arts, finds in the organization of the Institute potent means for its furtherance and in the JOURNAL OF THE INSTITUTE a universally recognized medium of publicity. The amount of material of importance brought under consideration at the meetings of the Institute and of its several Sections has of late been rapidly increasing, as also have the number of announcements and reports sent in from authoritative investigators in various fields of work. We have thus had presented to us the necessity of increasing each issue of the JOURNAL by a minimum of sixteen pages, or the alternati~,e of failing to do justice not only to our valued contributors but also to our membership-at-large. Your committee has chosen the former course as the only proper one under the circumstances. The cost of producing the JOURNAL, the requisite reprints, and the incidentals has consequently increased considerably during the year, but the earnings of the publication have almost kept pace with it. The fiscal year ended with a debit balance against the JOURNAL amounting to $419.17, a sum much less than the deficits of previous years, when the publication was run on a smaller scale and when its editions were not nearly so large as now. The system of awarding the Howard N. Putts Gold Medal and of several Edward Longstreth Medals of Merit in recognition of the most important contributions to the JOURNAL, inaugurated last year, has afforded the Institute, through your committee, a means of testifying to the authors an appreciation which could not otherwise be adequately expressed. That these awards have been accepted in the spirit in which they were made may well go without saying. The idea has commended itself from every point of view, and not the least of its favorable aspects is that the awards are made through the medium of the Committee on Science and the Arts, to whose co-operation in this direction the Editorial Committee is greatly indebted. Respectfully submitted, Louis E. LEvy, PHILADELPHIA, January I0, 1912. Chairman.
