Department of Mineralogy. 



The collection of Minerals has been much improved during the past year, as well by im- 

 portant additions that have been made to it, as by the general appearance of completeness 

 which a more finished classification and arrangement impart to it. 



This general arrangement is now in all essential particulars completed ; and the work of 

 the department has been for some time devoted to the detailed study of particular minerals 

 and to the crystallography of the collection. A popular guide was issued early in the 

 year, affording a sketch of the arrangement adopted in the distribution of the different 

 species throughout the collection. The symbols of the crystalline planes have been in- 

 scribed on prominent specimens in many of the more important mineral species, and on 

 others possessing special interest ; a work which is still in progress. 



The additions which have been made are of a valuable character, and amount to 1,200 

 mineral specimens. Of these, several have been acquired in consequence of opportunities 

 arising out of the International Exhibition. 



The collection of artificial crystals, which excited universal admiration in the Austrian 

 Court of the Exhibition, prepared by M. Carl von Hauer, of Vienna, was presented to Her 

 Majesty, with the rest of the very interesting objects sent to the Exhibition by the 

 Director of the Imperial and Royal Geological Survey at Vienna. Her Majesty has 

 placed the collection in the British Museum, and the Mineral Dejmrtment has thus become 

 enriched with a beautiful series of crystallographic illustrations of the most valuable 

 kind. 



Among the other specimens presented to the collection have been Pyrrhotine in fine 

 crystals, from Cav. Francfort, of Pallanza ; Chromite from Orsova, and Rock Salt from 

 Marmoros, from Professor Szabo. 



A beautiful crystal of Rock Salt from Wieliczka, from the Chevalier Schwartz, Austrian 

 Commissioner to the International Exhibition. 



Meerschaum from Cabanas ; Anglesite ; and Marbles from Cordova, from the Commis- 

 sioners for Spain to the International Exhibition. 



A series of specimens from the Canadian Court of the International Exhibition, from 

 Professor Sterry Hunt. 



The Collection of Aerolites has been increased by specimens representing four falls new 

 to the Collection, presented by the Asiatic Society of Calcutta, and by one of two small 

 fragments of a stone that fell at the North Inch of Perth on 17 May 1830; presented by 

 W. Nevill, Esq. The only record of this fall is in the handwriting of Dr. Thomson, of 



0.3. D Glasgow,
