have long stimulated the system.

M. M. The size of a large pea, of an ointment consisting of one part of
white precipitate of mercury to six parts of hogs' lard well triturated
together, to be rubbed on a part of the body every night, and washed off
with soap and water next morning, till every part is cleared; with lac
sulphuris twenty grains to be taken every morning inwardly. Warm saline
bath, with white vitriol in it. Flowers of sulphur mixed with thick gruel,
with hogs fat. With either of which the body may be smeared all over.

7. _Psora ebriorum._ Elderly people, who have been much addicted to
spirituous drinks, as beer, wine, or alcohol, are liable to an eruption all
over their bodies; which is attended with very afflicting itching, and
which they probably propagate from one part of their bodies to another with
their own nails by scratching themselves. I saw fatal effects in one such
patient, by a too extensive use of a solution of lead; the eruption
disappeared, he became dropsical, and died; I suppose from the too suddenly
ceasing of the great stimulus caused by the eruptions over the whole skin,
as in the preceding article.

M. M. The patient should gradually accustom himself to half his usual
quantity of vinous potation. The warm bath, with one pound of salt to every
three gallons. Mercurial ointments on small parts of the skin at a time. A
grain of opium at night instead of the usual potation of wine or beer.

8. _Herpes._ Herpes consists of gregarious spreading excoriations, which
are succeeded by branny scales or scabs. In this disease there appears to
be a deficient absorption of the subcutaneous mucus, as well as
inflammation and increased secretion of it. For the fluid not only
excoriates the parts in its vicinity by its acrimony, but is very saline to
the taste, as some of these patients have assured me; I believe this kind
of eruption, as well as the tinea, and perhaps all other cutaneous
eruption, is liable to be inoculated in other parts of the body by the
finger-nails of the patients in scratching themselves.

It is liable to affect the hands, and to return at distant periods; and is
probably a secondary disease, as well as the zona ignea, or shingles,
described below.

M. M. Poultice the eruption with bread and milk, or raw carrots grated, for
two or three whole days, to dilute or receive the discharged fluid, and
abate the inflammation; then cover the parts with fresh cerate mixed with
lap
