toms: Metallic taste in mouth, violent pain in abdomen,

Empty the stomach and give large doses of eggs.

slowness of respiration, feebleness of pulse, cold perspiration, 
aud contracted pupils. Treatment: Emetics (20 grains of 
sulphate of zinc, ipecacuanha, mustard, common salt, fol- 
lowed by copious drinks of warm water. Maintain respira- 
tion. Cold then hot water dashed on breast. Atropia, 
hypodermically administered. Strong coffec.

Puosrnorus.—Symptoms: Eructations of a garlic odour, 
violent gastric pain, vomiting, diarrhoea, vomited matters 
sometimes phosphorescent. Treatment: There is no anti-

purgatives, 
Porasstum, Bromide of.—Nervous stimulants. Opium. 
STRAMONIUM.—Treatment the same as in belladonna. 
STRYCHNINE.—In man strychnine causes twitching and 
rigidity of the muscles, followed by tetanic paroxysms, 
without loss of consciousness. In the intervals between the 
paroxysms the muscles are relaxed. Death may ensue from 
exhaustion between the fits of spasm or from aspnea during 
a paroxysm, owing to protracted rigidity of the muscles of 
respiration. ‘The fatal effects of an overdose of strychnine 
may be averted by the administration of chloroform or 
chloral, Tannic acid or vegetable astringents given freely.
