but very slightly impaired, particularly in the more simple cases,
and when the proximate cause is not seated in the encephalon; but

and the neck and face tumid and livid, the cerebral functions are
obscured, and the convulsions attended by stupor, delirium, &c., or
rapidly pass into, or are followed by, these states.”
