METHYL ALCOHOL (WOOD ALCOHOL OR SPIRIT, PYROXYLIC SPIRIT,
METHANOL OR WOOD NAPHTHA), CHaOH

This is formed by the destructive distillation of wood or molasses. It is a colour-
less, mobile liquid, having a peculiar, nauseating odour and a burning taste, and boiling
at 64/7 °C. It mixes with water in all proportions. It burns with a pale blue, non-
luminous flame, and its vapour forms an explosive mixture with air or oxygen* It is
largely used as a solvent and in the manufacture of organic dyes and varnishes. It is
also used to render rectified spirit unpalatable for trade purposes ; this mixture is known
as industrial methylated spirit, and is used in arts and manufactures under the name
of denatured alcohol or spirit. With a view to making denatured spirit nauseating and
abhorrent for potable use the Government of Bombay State have ordered that from the
first October 1949 its present denaturing ingredients, namely 0.5 per cent caoutchoucine
and^0,5 per cent pyridine should be supplemented by 0.5 per cent naphthalene. This
spirit, if used for potable purposes, will produce poisonous symptoms, which may prove
fatal. They have further ordered that after the first November 1949 all bottles, jars
and casks containing denatured spirit shall bear a label printed in red marked " Poison "
with skull and cross bones in tixe centre and a warning " For external use only, not to
be taken internally" in English and the regional language of the district.

Symptoms.—These may appear within an hour or after an interval of several hours.
