POISONOUS MUSHROOMS.--- Symptoms: Nausea, heat and pains in the
stomach and bowels; vomiting and purging, thirst, convulsions and
faintings, pulse small and frequent, dilated pupil and stupor, cold
sweats and death.

Treatment: The stomach and bowels are to be cleared by an emetic of
ground mustard or sulphate of zinc, followed by frequent doses of
Glauber of Epsom salts, and large stimulating clysters. After the
poison is evacuated, either may be given with small quantities of
brandy and water. But if inflammatory symptoms manifest themselves,
such stimuli should be avoided, and these symptoms appropriately
treated.

POTASH.--See Alkali.

PRUSSIC ACID, HYDROCYANIC.--See Acids.

POISON IVY.--Symptoms. Contact with, and with many persons the
near approach to the vine, gives rise to violent erysipelatous
inflammation, especially of the face and hands, attended with itching,
redness, burning and swelling, with watery blisters.

Treatment: Give saline laxatives, and apply weak lead and laudanum,
or limewater and sweet oil, or bathe the parts freely with spirits of
nitre. Anointing with oil will prevent poisoning from it.
