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).

(gcide) | biotin \bi"o*tin\ n.
a B vitamin (C10H16N2O3S) that aids in body growth; --
called also vitamin H and coenzyme R. It functions as a
coenzyme in many carboxylation reactions.

raw egg-whites. Rats or chick on a diet high in raw
egg-white may develop skin lesions and retarded growth,
which can be prevented by adding biotin to the diet.

1. A tough, white, aromatic resin, or gum, obtained from
different species of the Laurus family, esp. from
Cinnamomum camphara (the Laurus camphora of

obtainable as a white solid C10H18O, called also {Borneo
camphor}, Malay camphor, Malayan camphor, {camphor of
Borneo}, Sumatra camphor, bornyl alcohol, camphol,
and borneol. The isomer from Dryobalanops is
dextrorotatory; the levoratatory form is obtainable from
other species of plants, and the racemic mixture may be
obtained by reduction of camphor. It is used in perfumery,
and for manufacture of its esters. See Borneol.
[1913 Webster +PJC]
Note: The name camphor is also applied to a number of bodies
of similar appearance and properties, as {cedar
