ted by means of a syringe into the
mouth. If there are ulcers on the external skin, fine powder of bark seven
parts, and cerusia in fine powder one part, should be mixed, and applied
dry on the sore, and kept on by lint, and a bandage.

As sloughs in the mouth are frequently produced by the previous dryness of
the membranes, which line it, this dryness should be prevented by
frequently moistening them, which may be effected by injection with a
syringe, or by a moist sponge, or lastly in the following manner. Place a
glass of wine and water, or of milk and sugar, on a table by the bedside, a
little above the level of the mouth of the patient; then, having previously
moistened a long piece of narrow listing, or cloth, or flannel, with the
same liquor, leave one end of it in the glass, and introduce the other into
the mouth of the patient; which will thus be supplied with a constant
oozing of the fluid through the cloth, which acts as a capillary syphon.

The viscid phlegm, which adheres to the tongue, should be coagulated by
some austere acid, as by lemon-juice evaporated to half its quantity, or by
crab-juice; and then it may be scraped off by a knife, or rubbed off by
flannel, or a sage leaf dipped in vinegar, or in salt and water.

2. _Erysipelas_, St. Anthony's fire, may be divided into three kinds, which
differ in their method of cure, the irritated, the inirritated, and the
sensitive erysipelas.

_Erysipelas irritatum_ is attended with increase of irritation besides
increase of sensation; that is, with strong, hard, and full pulse, which
requires frequent venesection, like other inflammations with arterial
strength. It is distinguished from the phlegmonic inflammations of the last
genus by its situation on the external habit, and by the redness, heat, and
tumour not being distinctly circumscribed; so that the eye or finger cannot
exactly trace the extent of them.

When the external skin is the seat of inflammation, and produces sensitive
irritated fever, no collection of matter is formed, as when a phlegmon is
situated in the cellular membrane beneath the skin; but the cuticle rises
as beneath a blister-plaster, and becomes ruptured; and a yellow material
oozes out, and becomes inspissated, and lies upon its surface; as is seen
in this kind of erysipelas, and in the confluent small-pox; or if the new
vessels are reabsorbed the cuticle peels off in scales. This difference of
the termination of erysipelatous and ph
