34 ACCOUNTS, &C., OF THE BRITISH MUSEUM. 



Of 251 petrological specimens, microscopical sections have been prepared in the 

 Department, with a view to the proper discrimination and classification of the rocks they 

 represent. 



Towards the systematic work for the publication of a Scientific Catalogue of the 

 Mineral Collection, tlie ciystallography of the first and second divisions is nearly completed 

 to the end of the Monosulphides : and analyses have been made in the laboratory of 

 specimens of which the composition was doubtful in the species of Native Metals, of 

 Kaneite, Leucopyrite, Smaltine, Dyscrasite, Blende, Argentlte, Bismuthinite, Tetra- 

 dymite, and Onofrite. 



An analj'sis has also been made of the water of the Aiuseum well, of a green variety of 

 Garnet, and of the ingredients of rocks at Stonehenge and from Labrador. 



The Collection of Meteorites has been increased by four new falls, and by three belter 

 specimens of falls previously in the Museum. The most remarkable of these is a small 

 mass of iron which fell at Rowton, in Shropshire, on the 20th of April 1876, presented 

 by his Grace tlie Duke of Cleveland. 



The recorded number of students and visitors to the Department, for information in
