UNIVERSITi OF CALIFORNU Z SANTA BARBARA Appendix No. 16. — 1887 A BIBLIOGRAPHY OF GEODESY. By J. HO^V^ARr) GORE, B. S., Ph. D. INTRODUCTION. Although the restricted popuhir demand for a work peculiarly designed for the uses of the student and scientist liirely induces its author or compiler to forego its prei)aration, it is never- theless likely to be a mat ter of serious consideration in connection with the question of publicatiou by i)rivate enterprise. It is especially the case that, beyond the gratification of his own scientific tastes and the undemonstrative a])probation of the worthy few who appreciate the value of appli- ances which lessen the labor of learning, the compiler of so complete and exhaustive a Bibliog- raphy of Geodesy as that of Professor Gore can have had little to inspire his zeal and sustain his prolonged labor in au undertaking which, at the outset, involved the thorough exploration, in l>erson, of thirty-four of the principal libraries of America and Europe, the exploration of the minor libraries by proxy, and, in addition, a searching inquiry by correspondence with all the geodesists or mathematicians of both coniiuents. That Professor Gore has not lacked, during the i)repara- tion of his work, such inspiration as was derivable from the approbation of the competent, is attested by the courteous action of Colonel Uerschel, R. E., in placing at the Professor's service his own manuscript contribution to Pendulum Bibliography, as well as by the generous overtures from various institutions, among them being the International Geodetic Associatipn at Berlin, olfeiing to undertake the i)ublication of his book — a most gratifying recognition of his fitness for the work and of its anticipated value. The propriety of the reason, assigned in his preface, for declining to place the publication of his book in foreign hands, will hardly be disputed by any save those who are indifferent to the just fame of American scientists and to the continued honorable identification of the U. S. Coast and Geodetic Survey with the best work, and the successful promotion of the highest interests, of Geodesy. ftly own conviction of the propriety of Professor Gore's attitude was so clear that I could not, without a conscious disregard of duty, have declined the proffer of his manuscript to this Survey, for i)reservation and publication among th»v8cientiflc Appendices to its Annual Report, and so assuring, without cost for prejjaration or compilation, appropriate association of the n-cognized American Bureau of Geodesy with a complete Bibliography of Geodesy, American in inception and authorship and the first work of its kind. F. M. THORN, Superintendent, Coast and Geodetic Survey, Wmhington^ May 23, 1889. 313 PREFACE. The reason for the preparation of this work was the need of it felt by the compiler. He began in 1885 a History of Geodesy, but before proceeding far it was found very dithcult at any time to be sure that the literature regarding the operations of a given period had been exhausted. It was at once deemed best to collect titles as well as the works themselves. The excellent library facili- ties in the various technical departments iu Washington emphasized the feasibility of such an under- taking. The number of titles collected for this purpose only, so far exceeded the si)ecial lists as given in the various bibliographies of mathematics that many persons suggested an extension of the original plan, so as to make the compilation useful to others. In response to this proposition the various libraries in Washington were carefully searched, and during two trips to Europe nearly every library facility there has been exhausted. In order to procure titles of such recent works of living authors as might escape notice, owing to delay in obtaining a place in the library cata- logues, a circular letter was sent to every mathematician whose address could be obtained. Each circular had appended to it the titles of all of the known works of the recipient, with a request that omissions be supplied. This alone was the labor of several months, but was fully repaid in the gratifying assurances from many that nothing could be added, as well as in the few additional titles which tend towards making this work complete. Special efiort has been made to examine carefully catalogues of libraries, however small, bibli- ographies of the exact sciences, biographies of mathematicians, and trade lists of antiquarian books, in addition to such well-known sources as the"Koyal Society Catalogue of Scientific Papers," Eeuss, " Kepertorium," etc. A most opportune assistance was furnished by Col. John Herschel, E. E., who, through the courtesy of the Royal Society, and with the consent of the India OflQce, sent a manuscript sup- plement to his contribution to pendulum bibliography, which was published in " Operations , of the Great Trigonometrical Survey of India," Vol. v. From this veritable treasure seventy-two new titles were fouud, each in the body of this work followed by (H). Most cordial thanks are due Colonel Herschel for his aid, as well as the confidence displayed in unreservedly placing such valuable material in the hands of another. During the progress of the compiling, various overtures were made by institutions desiring to become tlie source from which the completed work should emanate, but it was deemed only jjroper that it should be published in the country which witnessed its inception and fostered its growth. Therefore it is with pardonable pride that the compiler sees the results of his labors issuing from an institution of his owu country, which throughout the world is the recoguized advance guard iu geodetic science. In this connection thanks should be tendered Mr. F. M. Thorn, Superintendent, and Mr. B. A. Colonna, Assistant in Charge of Office and Topography, of the D. S. Coast and Geodetic Sur- vey i. for their energetic interest in this undertaking. The title " Bibliography" may appear as high sounding or inappropriate to a work in which all the refinements of bibliographic science are not observed. The entire collation is not always given, since a large i)roportion of the books have appeared in but one edition. The only well defined purpose has been to give as much of the title as will enable one desiring the book to obtain it from any library possessing it, with the minimum effort to himself and the librarian. This object 315 316 UNITED STATES COAST AND GEODETIC SURVEY. was also iu view iu preparing the abbreviations for the serial publications, wbich, it is hoped, may be amplified without looking for their equivalents in their alphabetical place. It is a pleasure to acknowledge obligations to Mr. C. C. Darwin, librarian of the U. S. Geologi- cal Survey, for suggestions iu preparing these abbreviations. The scope of the work will easily make itself evident to the user. The intention was to include only such works as treated directly of the figure of the earth, or described operations which could be used iu determiniug that figure. The only digression from this plan will be seen in the case of the pendulum, where the theoretical side is also included. This was done because of the belief that the pendulum will soou become a more important geodetic instrument, when it may be necessary to reconsider some of its theoretical features. A few treatises ou surveying, bearing the word "geodesy" or its equivalent in the title, have been inserted with a remark indicating the character of the contents. As a rule, remarks are used simply to correct erroneous impressions which the title alone might make. The plan adopted is to use only one alphabet, in which will be found authors, abbreviations, and subjects. Full names of the authors have been given as far as possible, but in any subsequent repetition only the initials of their Christian names are given. The title will be found repeated under the name of each co-writer or each person named in the title. A dash ( — ) in a title refers to the first name given, as the one who wrote the review, or about whom the article was written. This method gives, so far as entry is concerned, equal prominence to all persons named. Under the authors, their works are arranged chronologically ; iu the case of serials, according to the date as given to the entire volume. This will be found advantageous when it is desired to find the full title from the abbreviated form as given under a subject. It is also believed that the insert ion of an abbreviated title iu the subject classification will be found helpful, as it will enable one to see at a glance if an author whose name appears under the desired subject has writteu upon the special theme sought for, without turning to the author catalogue. After each book title, and after the full title of each serial publication, there appears in paren- theses the name of the owner of the work from which the title as given was taken. Of course it does not intimate that the work in question can be found only there. When a book was once found it was not again looked for. As a rule, those accredited to European libraries could not, at the time of trial, be found in any library in America. It is impossible to mention here the names of all who have assisted in this work. But special thanks are due Mr. Nicholson, of the Bodleian, Oxford; Mr. Fortescue, of the British Museum; Professors Helmert and Foerster, of Berlin; Captain von Kalmar, of Vienna; Colonel Hennequin, of Brussels; the faithful assistants in the libraries of America and Europe who searched for dusty books so seldom called for that they became lost for the time, and to those who iu the University Library at Cambridge and the Royal Library of Munich used their holiday hours in looking for books which they alone possessed.
