gh with white
branny scales, which are full of chinks; often moist beneath, and itching.
The scales on the head or arms of some drinking people are a disease of
this kind. The perspirable matter designed for the purpose of lubricating
the external skin is secreted in this disease in a too viscid state, owing
to the inflammation of the subcutaneous vessels; and, as the absorbents act
too strongly at the same time, a viscid mucus is left adhering to the
surface of the skin.

In the leprosy of the Jews, described in the thirteenth and fourteenth
chapters of Leviticus, the depression of the sore beneath the surface of
the skin, and the hairs in it becoming white, seem to have been the
principal circumstances, which the priest was directed to attend to for the
purpose of ascertaining the disease.

M. M. Essence of antimony from 20 drops to 100 twice or thrice a day, with
half a pint of decoction of elm-bark; or tincture of cantharides from 20 to
60 drops four times a day; or sublimate of mercury, with much diluting
fluid. Acid of vitriol? Perhaps the cure chiefly depends on much dilution
with water, from two to four pints a day, in which elm-bark, or pine-buds,
or juniper-tops, may be boiled. Bath or Buxton water drank in large
quantities. Warm bath. Oil-skin bound on the part to confine the
perspirable matter. Ointment of tar and suet; or poultice for two or three
days, and then cerate with lapis calaminaris. Diet of raisins and bread.
Abstinence from wine, beer, and all spirits.

4. _Elephantiasis._ Leprosy of the Arabs. A contagious disease; the skin is
thickened, wrinkled, rough, unctuous, destitute of hair, without any
sensation of touch in the extremities of the limbs; the face deformed with
tubercles; the voice hoarse, and with a nasal tone. Cullen.

5. _Framboesia._ Yaws is said to be contagious and hereditary. It
principally affects the negroes in the West Indies. Edinb. Essays, Vol. VI.

6. _Psora._ Itch. A contagious prurient eruption. There are two kinds of
itch, that which appears between the fingers, and under the joints of the
knees and elbows; and that which seldom is seen in these places, but all
over the other parts of the body. The latter is seldom thought to be the
itch, as it does not easily infect even a bedfellow, and resists the usual
means of cure by brimstone.

If the itch be cured too hastily by rubbing mercurial or arsenical
preparations over the whole body, or on too great a part of it, many
