282 ODOROGRAPHIA. 
mode of procuring the gum consists in stripping the dead or un- 
sound bark from the wood, the more decayed portions of which are 
commonly saturated with the gummy exudation, and are found 
amalgamated with the woody fibre beneath in black crusts. 
Two kinds of frankincense are found in the market of Free- 
town, both of which are evidently the product of the same tree. 
The first can be partly recognized by the dark brown or black 
shining irregular fragments, and from apparently having a larger 
amount of gum blended with the woody fibre than the other, 
which is met with in smaller and less compact pieces, more friable, 
and of a lighter brown or yellow tint, being chiefly constituted of 
white woody particles cemented into masses by the excreted gum. 
Of these two varieties the latter is the least valued. The incense- 
like fragrance of these woody resinous excretions renders them 
available for a variety of uses, as a perfume and for fumigation. 
The native females triturate the gum with lime manufactured from 
sea-shells between two purposely adapted stones, and rub their 
bodies with the fine powder so produced. The bark is endowed with 
similar odoriferous properties in a lesser degree. The ignition of 
the gum is rapid; a bright yellow flame, attended with a black 
carbonaceous smoke, resulting. This is followed by the deposition 
of a viscid oleaginous matter and the evolution of a remarkably 
aromatic and semi-resinous odour, approximating to that produced 
from the common pastilles, for which they would form a substitute 
for use in the sick chamber or for perfuming the atmosphere of 
apartments. 
The gum is sold by the native traders under the designation 
Bungo, the same name as applied to the tree. The above in- 
formation is abstracted from a paper by Dr. Daniell contributed to 
the ‘ Pharmaceutical Journal’ [1] xiv. p. 400. A complete 
botanical description of this tree, which is of the Order Legumi- 
nose, suborder Cesalpinice, is given by Bennett at page 251 of the 
‘same volume.
