Pemphigus. Pompholix.

THE, first of these terms is from the Greek, and means a bubble; the second, pompholix, is from the same language, and means a water bubble. This is still more applicable to the disease in hand, which consists, in fact, in the raising up of the scarf skin in the shape of bubbles, containing a watery fluid. These bubbles are just like common blisters. They vary from the size; of a split pea to that of a hen's egg. They rise up very rapidly, and break in two or three days, leaving a raw surface which soon becomes covered by a thin crust.

Treatment. Similar to that for Rupia, with the addition of iodide of potassium (140), and applying the stick nitrate of silver to the whole surface of the ulcer, and a short distance beyond it on all sides, or the ointment (176). See treatment for syphilis.
