By an alteration in the disposition of the Table-cases in Room V. space has been acquired 

 for an extra Table, much wanted to display some recent additions to ihe Ceplnlopodous 

 Moliusca; and with this additional space, the whole of the exhibited Ammonites and 

 aUied gtnera have been re-arranged, and now occupy seven Table-cases in tiie Room 

 mentioned. 



The series of seven Half-Table Cases on the North side of the Room devoted to small 

 Mammalian remains, Crinoids, Foraminifera, &c., have in jjaitbeen re-aranged. Tiie Corals 

 have been removed from Room VI., and re-arrangeii in Room V., and space has thus been 

 gained for the exhibition of a more extensive series of British Eocene Shells, a large number 

 of which have been mounted on tablets and displayed. In the same Room (VI.) an extra 

 Table of Foreian Tertiary Shells has been exhibited. The whole of the Foreign Miocene 

 Shells not exhibited to ihe public have been collected together, and arranged in 64 drawers 

 in this Room ; and the greater portion of them has been named and regi>tered. A series 

 of slabs coniaining Fossil Plants from Solenhofen has been exhibited for the first time in 

 Room I. A hirge number of Crustacea and Radiata have also been arranged and 

 exhibited. 



The tine new Pledosaurus rostratus, already mentioned, has been mounted in a frame, 

 and exhil)itod on the North side of Room III. 



Numerous additions have been made to the exhibited collection of Vertebrate Animal 

 remains, especially from the Solenhofen Collection, obtained from Dr. Haberlein, many of 

 the specimens of wliich have been developed by the mason, and mountei.1 in frames. 



The inccrporaiion of these additional specimens has necessitated the partial re-arrange- 

 ment of the Case:^. The Wall-cases in Room III., containing the Ruminant rera;iins from 

 the Sewalik Hills, have been entirely re-arranged. 



The specimens from the Cavern of Bruniquel have been arranged in the Wall-cases at 

 the Webt end of Room VI.

Department of Mineralogy. 



In the Mineral Department the following work has been done during the past year. 



The Crystallogiaphy of the collection has made proiiress, and the inscription of the 

 symbols on the crystalline planes of important species has been carried forward. 



The numerous, and generally speaking very inferior Mineral specimens contained in 

 drawers in the basement have been carefully examined : the best have been selected, cleaned, 

 and, where they were not merely duplicates, have been arranged in their places in the 

 reserve drawers. 



A new Wall-case has been placed in Room I., to correspond with that in which the 

 Aerolites (stony Meteorites) were arranged la=t year. In it the iron Meteorites have been 

 arranged. Several of these have been polished and etched to exhibit the crystalline 

 structure which constitutes one of their most important peculiarities. 



The ends of two more Table-cases have been fitted with glazed compartments for the 

 exhibition of unusually large and otherwise remarkable specimens. 



New Species-labels have been placed with the Minerals in the first 15 cases, and 

 labels inscribed with the localities have been aflBxed to the specimens in 66 of the drawers 

 containing reserve and duplicate minerals. 



The arrangement of the two cases containing the pseudomorphs, begun last year, has also 

 been completed. 



The Mineral Collection has received additions during the past year, amounting to 634 in 

 number, some of which aie of a very choice character. These have been registered, 

 labelled, and incorporated in the collection.
