SCIENTIFIC AND LEARNED SOCIETIES OF GREAT BRITAIN AND IRELAND: LISTS OF THE PAPERS READ FROM JANUARY 1900 TO JUNE 1901 Price 7s. 6d. each Annual Volume. YEAR-BOOK OF THE SCIENTIFIC AND LEARNED SOCIETIES OF GREAT BRITAIN AND IRELAND. COMPILED FROM OFFICIAL SOURCES. "British Societies are now WELL REPRESENTED in the Year-Book of the Scientific and Learned Societies of Great Britain and Ireland.'"-(Art. Societies in the New Edition of the Encyclopædia Britannica, vol. xxii.) "The YEAR-BOOK OF SOCIETIES is a Record which ought to be of the greatest use for the progress of Science."-Lord Playfair, F.R.S., K.C.B., PastPresident of the British Association. "It goes almost without saying that a Handbook of this subject will be in time one of the most generally useful works for the library and the desk."-The Times. "Some idea of the limitless field which is covered by unselfish workers in the cause of Science may be gathered from the YEAR-BOOK OF THE SCIENTIFIC AND LEARNED SOCIETIES OF GREAT BRITAIN AND IRELAND. The Book is INVALUABLE, for it gives a synopsis of all that has been done during the past year in fourteen departments of research, and the student of any of these subjects can easily lay his finger on the work done in the course of the year.' Glasgow Herald. "An exceedingly well drawn up volume, compiled with great accuracy, and INDISPENSABLE to any one who may wish to keep himself abreast of the scientific work of the day."-Edinburgh Medical Journal. "It is a book which ought to be found in every library of reference." -Guardian. "Is an INVALUABLE INDEX to the Literature of British Science."-Westminster Review. "The outcome of a good idea, well carried out."-Manchester Examiner. "The YEAR-BOOK OF SOCIETIES fills a very real want. The volume will become a Scientific Directory, chronicling the work and discoveries of the year, and enabling the worker in one branch to try his hand in all that interests him in kindred lines of research."-Engineering. "Cannot fail to be of IMMENSE SERVICE to all who are interested in Scientific work."-Glasgow Medical Journal. "Nous avons parlé, il y a deux ans, du YEAR-BOOK OF SCIENTIFIC AND LEARNED SOCIETIES OF GREAT BRITAIN AND IRELAND, publié depuis 1884 par la librairie Ch. Griffin, de Londres. Nous venons de recevoir la 5e année de cette très utile publication. Les Societés savantes de l'Angleterre devraient tenir toutes à honneur de faciliter la tâche de l'éditeur."-Revue Historique, Sept. 1888. Copies of the FIRST ISSUE, giving an Account of the History, Organisation, and Conditions of Membership of the various Societies, and forming the groundwork of the Series, may still be had, also Copies of the following Issues. LONDON: CHARLES GRIFFIN & Co., LIMITED, PREFACE. :0: “British Societies are now well represented in the 'Year-Book of the Scientific and Learned Societies of Great Britain and Ireland.'"-(Art. Societies in New Edition of Encyclopædia Britannica, vol. xxii.) THE FIRST ISSUE of the YEAR-BOOK OF SOCIETIES (for 1884) offered to the Public a concise Review of the History, Organisation, and Conditions of Membership of the various Scientific and Learned Societies of Great Britain and Ireland, compiled from data furnished by the Societies themselves. Since that date, Seventeen Annual Volumes have been issued, giving a CHRONICLE of the Work done during the previous year by the same Societies (as well as by those more recently organised), together with the necessary information as to official changes. In accordance with suggestions made to the Publishers last year on behalf of the ROYAL SOCIETY, the ROYAL GEOGRAPHICAL SOCIETY, and other leading institutions, respecting the date of publication, it has been decided that, in future, this shall correspond as closely as possible with the sessional year (SeptemberJune), instead of with the calendar year, as hitherto. Henceforth, forms for filling up will be sent out on the 1st of June every year, returnable by or before the end of the month; and the YEAR-BOOK, incorporating the work of the previous sessional year, will be published at the commencement of the ensuing session. The PRESENT ISSUE has therefore been enlarged, in order to fill the gap of six months that would otherwise have been created; and the LISTS OF PAPERS now given comprise, with few exceptions, those read before the various Societies during the eighteen months which have elapsed since the last issue, viz., January 1900 to June 1901. In most instances the LISTS OF PAPERS have been contributed directly by the Societies. Where Papers are not given, their absence |
