among which may be particularized the different 
varieties of bitumen, from the fluid naphtha, to 
the solid jet (pitch coal of Werner) ; a suite of the 
elastic bitumen from Derbyshire, in its different 
states of induration; with this is placed an in¬ 
flammable fossil substance found by Humbolt in 
South America, where it is called Dapeche, 
which has several of the properties of the com¬ 
mon caoutchouc or India rubber; also the retin- 
asphaltum found at Bovey, and a peculiar re¬ 
sinous substance lately discovered in digging 
the tunnel at Highgate.—To the varieties of 
amber is added some w'ood converted into brown 
coal, and a small capsular fruit, both of which 
are found, together with that inflammable sub¬ 
stance, on the coast of Prussia.—The mellite 
or honey stone, strictly speaking a saline 
substance, but geognostically related to amber,

Beraiogicaily simple, may be considered as objects of geology (such 
as varieties of coal, basalt, clay, slate, &c.) will find a place in an
