Give chloride of ammonium in 30
grain doses to prevent delirium; strychnine or digitalin
hypodermically.
_Method of Extraction from the Stomach._--Neutralize the contents of the
stomach, if acid, with sodium carbonate; place them in a retort and
carefully distil. Collect the distillate, mix with chloride of calcium
or anhydrous sulphate of copper, and again distil. Agitate distillate
with dry potassium carbonate, and draw off some of the supernatant fluid
for testing.
_Tests._--Odour. Dissolves camphor. With dilute sulphuric acid and
bichromate of potassium turns green, and evolves aldehyde. Product of
combustion makes lime-water white and turbid.
=Methyl Alcohol: Wood Naphtha.=--Used to produce intoxication by
painters, furniture-polishers, etc.
_Symptoms_ are those of alcoholic poisoning, but vomiting and delirium
are more persistent. Total or partial blindness may follow as a sequel
of optic atrophy. A fatal result not infrequently follows.
