     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}).
