[1913 Webster]

Note: There are many varieties of turpentine. Chian
turpentine is produced in small quantities by the
turpentine tree ({Pistacia Terebinthus}). Venice,
Swiss, or larch turpentine, is obtained from {Larix
Europaea}. It is a clear, colorless balsam, having a
tendency to solidify. Canada turpentine, or Canada
balsam, is the purest of all the pine turpentines (see
under {Balsam}). The Carpathian and Hungarian varieties
are derived from {Pinus Cembra} and {Pinus Mugho}.
Carolina turpentine, the most abundant kind, comes from
the long-leaved pine ({Pinus palustris}). Strasburg
turpentine is from the silver fir ({Abies pectinata}).
