eastward. It has been said to grow in the forests near the river Var, 
but I have never met with any botanist who felt sure that it still 
exists there. The more adventurous visitors staying at Cannes should 
try to clear up this doubtful question. From Marseilles to Genoa, the 
only certain habitats for this plant are those in the more mountainous 
districts between Toulon and the Esterelles. Styrax officinale, Linn., 
yields a resinous balsamic juice, obtained by crushing the bark, which 
is known as storax, and used in perfumery and medicine. “Styrax 
Benzoin, a native of Sumatra, Borneo, ete., yields the resin called Ben- 
zoin. Benzoin is employed medicinally in chronic pulmonary disorders, 
and also by perfumers. It is used in Roman Catholic churches in the 
composition of incense.”*
