“ Half an ounce of the ordinary watery extract is fatal to dogs 
in about thirty hours, when given by the mouth; half that 
quantity in twenty-four hours when introduced into a wound ; 
and even smaller doses than these are more speedily fatal when 
injected into the jugular vein.” —Chrzstison. 
Post-mortem Appearances.—‘ Inanimals poisoned by belladonna, 
death results partly from paralysis, partly from coma ; the blood 
remains fluid, and putrefaction sets in very early ; the lungs, and 
sometimes also the brain and its membranes, are congested ; but 
no inflammatory appearances can in general be detected.”—
