Note 45 — ADDENDA.

The petechiæ and other eruptions vary in size and colour. They are mostly small and distinct, but sometimes run together and form broad maculæ, which now and then end in carbuncles. Their colour in many instances is livid or black, in others (when the disease is milder) purplish, in some reddish. In convalescents, they turn first red, then yellow, and afterwards disappear. They are so common in the beginning of the plague, that scarcely any one dies without them; though buboes and carbuncles are not observable. Hence those who have never seen the plague under all its forms are apt to be deceived respecting the nature of the disorder.
