formerly constituted the collection of the late 
Right Hon. Charles Greville. These consolidated 
collections are arranged in cabinets containing 
upwards of 640 drawers, independently of the 
specimens exhibited in the glazed compartments 
above, which form a suite for study, and respec¬ 
tively indicate the contents of the drawers below. 
In the arrangement of this collection a natural or¬ 
der founded on external characters has been 
followed; not, however, without consulting the 
chemical composition of the substances, so far as 
convenience would admit. In order to facilitate 
the distinction of the specimens in the glazed 
compartments, the separations of their different 
genera and species are marked by lines of various 
colours, corresponding to those on the tickets 
which bear their respective names and synonyms. 
As, besides these, almost every specimen has its 
habitat (or place where it is found) written upon 
it, to which is annexed a ticket indicating the ex¬ 
ternal character for the illustration of which the 
specimen is deposited, it would be unnecessary to 
repeat the same in this synopsis, which can be in¬ 
tended only to give a summary view of the con¬ 
tents of the different compartments, or cases. 
Each of these has its number iuscribed on the 
upper part of the middle square of glass. 
(Case 1) Contains the combustible substances, 
among which may be particularized the different 
varieties of bitumen , from the fluid naphta, to the 
solid
