MINERALOGY. 



THE GENERAL COLLECTION. 



The General Collection is contained in a series of table-cases ArraJ 

 numbered from 1 to 41, commencing at the entrance to the meut - 

 gallery : the relative positions of these cases will be clear from 

 the accompanying plan, which further shows that the specimens 

 are arranged as if each pair of opposite cases formed a single 

 large case extending across the gallery. Most of the larger 

 specimens are shown in the glazed ends of the table-cases, 

 and in general are of the same species as the smaller speci- 

 mens displayed in the tops above them. An alphabetical 

 index of the names and sj'nonyms of all the species and 

 varieties with references to the table-cases in which they are 

 exhibited is given in pages 92-114; for greater precision in 

 the statement of the position of a mineral in the collection every 

 table-case has been divided into eight compartments repre- 

 sented by the letters a, b, c, d, e, f, g, h. 



Besides the General Collection are exhibited a series of 

 Pseudomorphs in cases 42 and 43 ; collections of Meteorites 

 and of Crystals in the table-cases of the pavilion ; and 

 further, a collection of Rocks in the wall-cases of the pavilion 

 and the gallery. 



The following sketch will serve to indicate the general features of the Class 

 classification of the General Collection, and, by giving the numbers of tion.l 

 the particular table-cases, through which the principal divisions, sec- 

 tions, &c, are distributed, it will serve as a guide for finding any par- 

 ticular Minerals. The names of the species, as well as of important 

 varieties, will be found within the table-cases, associated with the 

 Minerals to which they belong. 



The Collection of Minerals is arranged in five principal Divisions. 

 These are — 



Division I. The Native Elements. Cases 1 and 2. 



Division II. The Compounds of Metals, with 



(i.) Elements of the Arsenic group (the Arsenoids, 

 viz., Bismuth, Antimony and Arsenic). Case 

 BM 3a, b, c.
