mical composition of the substances, so far as 
convenience would admit. Each of the glazed 
table-cases has its number inscribed 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 na'phtha to the 
solid jet (pitch coal of Werner) and the mineral 
caoutchouc from Derbyshire. (See British Collec¬ 
tion ; Derbyshire.) With these is placed an in¬ 
flammable fossil substance found by Humboldt 
in South America, where it is called dajpechej 
which has several of the properties of the com¬ 
mon caoutchouc or India rubber ; also the retin- 
asphaltum or retinite^ found at Bovey, and that 
from Wildshut and Bergen in Bavaria 5 the pe¬ 
culiar resinous substance discovered in digging 
the tunnel at Highgate, &c.— Amber^ the yellow 
and white varieties: fragments inclosing insects. 
— Sulphur^ crystallized and massive, with selenite, 
sulphate of strontian, &c.; the same found sub¬ 
limed near the craters of volcanos.— Graphite^ 
commonly called black lead, massive, dissemi¬ 
nated in porcelain earth, &c. (See British Col¬ 
lection : Cumberland.)—A few specimens of 
black coal.—Brown coal^ to which belongs the 
well known Bovey coal. — Dysodile^ or papyra¬ 
ceous brown coal. Among the specimens of 
anthracite or kohlenblende (to which may be re¬ 
ferred the Kilkenny coal) is a specimen from 
Kongsberg in Norway, with native silver.
