292 ORD. X-VIL.. Bicornes. STYRAX OFFICINALE, 
parts of Europe, yet the resinous drug which it produces is only 
to be obtained in perfection from these trees growing in Asiatic 
Turkey.* The Storax issues in a fluid state from incisions made in 
the bark of the trunk, or branches, of the tree; and as.it was for- 
merly the custom to collect and export this gum-resin in reeds, 
it obtained the name of Styrax calamita. But-the only two kinds 
of Storax* now to be met with in the shops may be divided into 
the pure and the common Storax; the first is usually in irregular 
compact masses, free from impurities, «of a yellowish or reddish 
brown appearance, and interspersed with whitish tears, somewhat 
like Gum ammoniac or Benzoin; it is extremely fragrant, and, upon 
the application of heat, readily melts. This has been called Storax 
in the lump, red Storax, and the separate tears, Storax in the tear. 
The common Storax is in large masses, very light, and bears no 
external resemblance whatever to the former Storax, as it seems 
almost wholly composed of dirty saw-dust merely caked together 
by the resinous matter; and though much less esteemed than the 
purer kinds of Storax, yet wen freed from the woody part, we 
are told that it possesses more fragrance, and is superior to the 
other kind. Rectified spirit, the common menstruum of resins, 
readily dissolves the Storax, which may be inspissated toa solid 
consistence, as directed for the Styracis purificatio in the London 
Pharm. without sustaining any considerable loss of its sensible 
qualities.

* It is necessary to observe, that no reference is here made to the Styrax liquida, 
which is produced from a very difierent tree, viz. the Liquidamber styraciflua; and, 
according to Monardes, is obtained by boiling the branches in water, which 
occasions the drug to separate, and rise to the surface, when it is skimmed off for
