in the field in North America, by which the nature and chronological 

 superposition of the Paleeozoic rocks of a large part of North Ame- 

 rica, and especially of the State of New York have been accurately 

 defined and mapped. Also for his labours in general Palaeontology, 

 by which he has collected and classified a great series of North 

 American organic remains from the lowest Silurian of New York to 

 the tertiary mammalia of the Western States inclusive ; and for his 

 valuable works, published and in progress, on the Geology and Palae- 

 ontology of New York, the publication of part of which has already 

 been of the highest value to European geologists, especially in afford- 

 ing them the means of comparing the general structure of the rocks 

 and the succession of life in the Paleeozoic rocks of Europe. 



Report of the Library and Museum Committee. 



Library. 



Of the books and pamphlets selected as duplicates from those be- 

 queathed by the late Mr. Greenough and from the Society's Library, 

 nearly all have been distributed as directed by the Council, accord- 

 ing to the recommendations of the Special Committee. The Royal 

 Geographical Society, the Geological Survey, and London University 

 College have received about 450 volumes, and the Geological Society 

 of Dublin have selected 30 volumes. It is proposed, in compliance 

 with the application of Professor Oldham, that the majority of the re- 

 mainder shall be presented to the Calcutta Library of the Geological 

 Survey of India. 



In accordance with the recommendation of the Library Committee 

 of last year, a fair copy in manuscript has been made of a Catalogue 

 of the additions of books to the Library. 



The books, maps, prints, &c. received during the past year have 

 been, as far as necessary, bound or mounted, and arranged in their re- 

 spective places on the shelves in the Society's Library, or in the Map- 

 cases and Portfolios. 



The printing of the Index* prepared by Mr. Ormerod is in pro- 

 gress : four sheets are in the press, and it is expected that the whole 

 will be completed by Lady Day next. We are happy to be able to 

 state that nearly 100 copies have been subscribed for; and as a limited 

 number is to be printed, it is suggested that those Institutions and 

 Fellows who are desirous to obtain a work so indispensable for the 

 advantageous use of the Society's publications should at an early date 

 add their names to the list of those intending to take copies. 



The number of British and Foreign Institutions to which the 

 Quarterly Journal of the Society is presented, and from most of 

 which their publications are received, has increased during the past 

 year and now amounts to above 100. The papers bearing on Geo- 

 logical Science which are contained in such publications, as well as in 

 the purchased Scientific Journals, continue to be noticed in the bi- 

 bliographical list printed in the Quarterly Journal.
