NORTH GALLERY. 
[upper 
NOBTH GALLEKY. 
The six rooms forming the North Gallery are numbered over 
the doorways. The first four of these rooms contain sixty 
large and four small Table Cases in which the Collection of 
Minerals is displayed, besides two Cases containing the 
Meteorites. The Wall Cases and a few small Table Cases in 
these Rooms, and the whole space in Rooms Y. and VI. are 
devoted to Fossils. 
DEPARTMENT OF MINERALOGY. 
The sixty large Table Cases containing the Minerals are numbered 
consecutively. Commencing at the east end of the Gallery in Room I. 
and passing down the south side of the four rooms, the numbers return 
up the north side, the sixtieth table standing opposite to the first. 
Corresponding with this order of the numbers on the Table Cases is that 
of the Minerals arranged in them. 
The following sketch will serve to indicate the general features of the 
arrangement, and, by giving the numbers of the particular Table Cases, 
through which the principal divisions, sections, &c, are distributed, it will 
serve as a guide for finding any particular 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. 
At the eastern end of Room L, adjoining the wall, are two glazed 
Cases. In these, the important Collection of Meteorites is displayed. 
In Case A. are seen the stony varieties, the "Aerolites." Of these 
there are a large number characterised by the presence of minute 
stony spherules. They are the " Chondritic" Aerolites : they all con- 
tain meteoric iron in fine particles disseminated through them, and 
the more chondritic varieties are on the left hand side of the Case. 
Among other kinds of aerolites the carbonaceous stones that fell at 
Cold Bokkeveldt, Kaba, Grosnja, and Montauban, on the right hand 
end of this Case, are remarkable. So is the great chondritic aerolite 
that fell at Parnallee, in Madras, on February 28, 1857; presented 
to the Museum by Sir Wm. Denison, the Governor of that Presi- 
dency. The stone that fell at Busti on December 2, 1852, is also 
in this Case. It is remarkable for containing crystalline calcium 
sulphide, associated with Enstatite and Augite. 
in Case B. are displayed, on the left extremity of the Case, the 
Sidorolites, while the rest of the space is occupied by the Aero-siderites. 
The former are masses of meteoric iron containing stony matter ; the
