reflex movements, hurried and shallowed respiration, and death. The
pupils are usually contracted, and the urine, if not suppressed, is dark
in colour, or even black. Patients often improve for a time, and then
die suddenly from collapse. When the poison has been absorbed through
the skin or mucous membranes, a mild form of delirium, with great
weakness and lividity, are the first signs.
Post-Mortem.--If strong acid has been swallowed, the lips and mucous
membranes are hardened, whitened, and corrugated. In the stomach the
tops of the folds are whitened and eroded, while the furrows are
Treatment.--Soluble sulphates which form harmless sulpho-carbolates in
the blood should be administered at once. An ounce of Epsom salts or of
Glauber's salts dissolved in a pint of water will answer the purpose
admirably. After this an emetic of sulphate of zinc may be given. White
of egg and water or olive-oil may prove useful. Warmth should be applied
to the body.
Fatal Dose.--One drachm, but recovery has taken place after much
larger quantities, if well diluted or taken after a meal.

toxic than carbolic acid.
