Of the leaves of P. Terebinthus are very small sacs, three or four 
of which communicate together; they are of a pink colour, 
and have a terebinthinate and astringent taste, and appear to 
be caused by the presence of an aphis. 
Chemical composition. — According to Plickiger and re 
a bury, the solution of Hast Indian mastich in acetone or benzol 
has the same optical properties as that of true mastich ; it 
deviates the ray of polarised light to the right. (Pharma- 
cographia.) Kast Indian mastich has been examined by Fielding, 
who found that it differs from the resin of P. Lentiscus in being 
entirely soluble in hot alcohol, becoming only slightly turbid 
on cooling, whereas 25 per cent. of true mastich remains . 
insoluble in tot alcohol. On the other hand, the latter resin 
is entirely soluble in turpentine, whereas East Indian Mastich 
dissolves in hot turpentine but throws down about 25 per cent. 
0n cooling in cauliflower-like crystalline grains. It approaches 
to the oleo-resin of ‘the European P. Terebinthus in these 
respects, but differs from it in being quite soluble in ether, 
Whereas that oleo-resin gives a cloudy solution with ether, 
Whether hot or cold. True mastich contains a trace of volatile 
oil and two resins, mastichic acid and masticin. The first is pe
