Translations of ancient scientific and mathematical treatises by Professors John G. Winter and L.C. Karpinski are also to be found in two other volumes of this series, while certain studies in Roman Law and administration by Professors A.E. Boak and J.H. Drake and a discussion of "Greek Themes in Modern Musical Settings," by Professor A.A. Stanley, bring the volumes issued down to the present time. Accompanying this series are a number of Humanistic Papers, including a discussion and symposium on the value of classical training in American education, and a biography of Professor George S. Morris by Professor R.M. Wenley. Two volumes in a scientific series have also appeared: "The Circulation and Sleep," by Professor J.A. Shepard of the Department of Psychology, and "Studies in Divergent Series and Summability," by Professor W.B. Ford of the Department of Mathematics. Two volumes of the Publications of the Astronomical Observatory, dealing with the spectroscopic investigations for which the Observatory is now particularly well equipped, have also appeared. Also to be noted are four numbers of a series of Publications by the Physical Laboratory and seventy-two "Occasional Papers from the Museum of Zooelogy," as well as four volumes in a "University of Michigan Historical Series," including "A History of the Presidents' Cabinets," "The English Rule in Gascony, 1199-1259," "The Color Line in Ohio," and "The Senate and Treaties (1789-1817)," (the last by Professor J.R. Hayden), and two volumes in a series of Economic Studies. A "History of the Chemical Laboratory," by Professor E.D. Campbell, should also be mentioned. From time to time there have been issued compilations of the publications of members of the University Faculties. These have shown an ever-increasing body of books, articles, and reviews which may be taken as another concrete evidence of the activity of the members of the Faculty in their various fields. The first two of these lists were issued through the medium of a little informative sheet issued for the University for some years by the Alumni Association, known as the _News-Letter_. The data were far from complete but the published total was not unimpressive. Later the University Library took up the work, while the last two lists of this character were made by Dean A.H. Lloyd, of the Graduate School, as regular University Bulletins. These cover the period from July 1, 1909 to June 30, 1919 and include over one hundred volumes exclusive of ordinary handbooks and textbooks. These two lists give some 1,700 titles.
