When the violence of the disease approached the heart, the gums were blackened.
The sleep broken, troubled by convulsions, or by frightful visions, was worse than the waking hours; and when the reason sank under a delirium which had its seat in the brain, repose utterly forsook the patient's couch.

Soon the breath infected the air with a fetid odor, the lips were glazed, despair painted itself in the eyes, and sobs, with long intervals of silence, formed the only language.

From each side of the mouth, spread foam tinged with black and burnt blood.
Blue streaks mingled with the yellow all over the frame.
