und geologische Verbreitung,' 2 vols ; the continuation of L. Reeve's ' Conchologia Iconica; ' H. Abich's ' Geologische Beobachtungen auf Reisen in der Gebirgslandern zwischen Kur und Araxes ; ' Professor Gervais's 'Recherches sur l'Anciennete de l'Homme et la periode Quaternaire ; ' Stoppani's 'Paleontologie Lombarde,' 4th series ; and the third volume of the great French edition of the works of Aristotle in Greek and Latin, containing the portion of his writings relating to Natural History.
The Library has been increased during the past year by a great number of valuable donations, including, besides periodicals and the publications of Learned Societies, many separate works of importance, such as : —
Barrande's ' Systeme Silurien de la Boheme,' vol. ii., ' Cephalopodes Siluriens,' Text and Atlas ; Greppin's ' Essai Geologique sur la Jura Suisse;' 0. Heer's 'Fossilen Hymenopteren aus OEningen und Radoboj ;' Eadmann's ' Expose des Formations Quaternaires de la Suede;' F. J. Pictet's ' Materiaux pour la Paleontologie Suisse' (the commencement of a fourth series) ; Zigno's ' Flora fossilis Formationis Oolithicae ' (the completion of vol. i.) ; the second edition of Dawson's ' Acadian Geology ; ' the late Professor Hornes's ' Fossilen Mollusken des Tertiarbeckens von Wien,' Bivalves 7 and 8 ; the conclusion of Gaudry's ' Animaux fossiles de l'Attique;' W. K. Parker's ' Monograph on the Structure and Development of the Shoulder-girdle ; ' Gumbel's ' Geognostiche Beschreibung und Karte des ostbayerischen Grenzgebirges,' with a magnificent Atlas ; and the publications of the Geological Survey of the Grand Duchy of Baden, containing Maps and Descriptions of the Environs of Lahr and Offenburg, and of Mohringen and Mosskirchen.
A good many Maps and Plans have been added to the Society's Collection ; they include the Maps of the Geological Surveys of the Netherlands (2 sheets), Sweden (4 sheets), Austria (2 maps), and Victoria (3 maps), those of the British Ordnance Survey, a Geological Map of the South-east of England presented by W. Whitaker, Esq., and a Geological Map of South Devonshire, prepared and presented by Dr. Holl.
Great inconvenience has often been experienced from the difficulty of arranging detached pamphlets, parts of serial works, and similar publications so as to render them easily accessible. A set of pigeon holes has now been made for the reception of such papers ; and in these they may be kept in alphabetical order, and made more available for the use of the Fellows until they can be bound into volumes.
Mr. Skertchley resigned the office of Library Assistant at the end of the year 1868, and Mr. F. H. Waterhouse has been appointed his successor.
