agreeable hyacinthine odour, melts at 33° C., and boils at 250° 
C. Styracin and cinnamic acid yield with oxidizing agents 
oil of bitter almonds and benzoic acid, and when styrol is 
treated with chromic acid and then boiled with water, benzoic 
acid is obtained. After saponifying storax with an alkali, and 
subjecting the alcohols to fractional distillation, Laubenheimer 
- (1872) obtained a distillate having the properties of benzyl 
alcohol ; this is a colourless liquid of a weak but fragrant odour 
having the specific gravity 1-06 and the ‘composition C7 H80. 
Storesin, C°SH°80§, is amorphous, melts at 168° C. (8 storesin 
at 145° C.), and dissolves readily in alcohol, ether, petroleum, 
benzin, and potassa, forming with the latter a crystalline 
compound, Mylius (1882) prepared styrogenin, C2°H*9O3, 
from that portion of storax which is soluble in boiling benzin; 
after treating it with an equal weight of sulphuric acid, boiling 
with water, and washing with ether, white crystals are left 
_which are easily soluble in chloroform, melt at 350° C., dissolve’ 
in cold sulphuri¢ acid, being reprecipitated by water, and yield 
with warm sulphuric acid a yellowish-red solution, which with - 
water precipitates uncrystallizable resin. (Stillé and Maisch.) 
Commerce.—The imports of this article into Bombay in 1881- 
82 amounted to 363 cwts. from the Red Sea ports. Value, 
Rs. 16,154. In India it is often adulterated with coal tar. 
Under the name of Usturak (crvpat), a bark is sometimes 
found in the Indian drug shops; it is said to be imported 
: from Turkey, and occurs in half quills several inches long, of 
a light brown colonr, the external surface soft and corky, but * 
the inner portion resinous and aromatic; it is probably the 
bark of Storaz officinalis, Linn., the tree which produced the 
storax of the ancients. (Of. Pliny xii. 55.)
