g. — A series illustrating the manufacture of steel, brass, and other 

 metallic compounds or alloys. 



h. — An extensive series, illustrating the rocks which either have been 

 or may be advantageously employed for Architectural or Engineering 

 purposes. 



i. — The various cements, bricks, tiles, or other artificial mineral 

 compounds which may be, or have been, employed for the same pur- 



k. — A series of the substances used in the manufacture, and illustrat- 

 ing the manufacture itself of British porcelain, earthen- ware, and the 

 coarser potteries. 



I. — A series of soils, with their analysis attached, and a notice of 

 such circumstances connected with the climate and the situation of 

 the localities where they occur as can be obtained, accompanied by 

 such specimens of the subsoils or rocks in which they rest as can be 

 procured. 



In the Laboratory, analyses of mineral substances, such as ores, 

 rocks, soils, &c. are made at a regulated price for the public, who not 

 only thus obtain correct information without fear of fraud from interest- 

 ed motives, but also do so at moderate cost. Analyses are also executed 

 for such Government Departments as may desire them ; and pupils, as 

 above mentioned, are received. 



The Model Department will consist (and numerous important models 

 are already in the collection) of models to illustrate mining operations, 

 from the most simple conditions up to the most complicated of mining 

 machinery, and of such operations connected with mines as can be well 

 shewn by models, not only British but foreign, and of furnaces and 

 other works for the reduction of the metals. The tools and instru- 

 ments used in mining in different countries, with specimens of the ropes, 

 chains, &c. employed, form also part of this collection. 



In the Mining Record Office, not only will the plans and sections 

 which relate to British mining be accumulated, but all documents relat- 

 ing to foreign mines which can be obtained, will be added to the collec- 

 tion, and it is expected, from the arrangements which have been made, 

 that much important information will thus be brought together. Geo- 

 logical maps and sections of various countries will be here assembled, 

 and it is intended eventually to form a Library, containing works in
