a, the leaves of which are bruised in a mortar, and applied
on the ulcers for two or three days, and then some more lenient application
is used.

A poor boy, about twelve years old, had a large scrophulous ulcer on one
side of the chest beneath the clavicle, and another under his jaw; he was
directed, about three weeks ago, to procure a pound of dry oak-bark from
the tanners, and to reduce it to fine powder, and to add to it one ounce of
white lead in fine powder, and to cover the ulcers daily with it, keeping
it on by brown paper and a bandage. He came to me a few minutes ago, to
shew me that both the ulcers are quite healed. The constant application of
linen rags, moistened with a solution of an ounce of sugar of lead in a
pint of water, I think I have seen equally efficacious.

14. _Scorbutus suppurans._ In the sea-scurvy there exists an inactivity of
venous absorption, whence vibices and petechiae, and sometimes ulcers. As
the column of blood pressing on the of origins of the veins of the lower
extremities, when the body is erect, opposes the ascent of the blood in
them, they are more frequently liable to become enlarged, and to produce
varixes, or vibices, or, lastly, ulcers about the legs, than on the upper
parts of the body. The exposure to cold is believed to be another cause of
ulcers on the extremities; as happens to many of the poor in winter at
Lisbon, who sleep in the open air, without stockings, on the steps of their
churches or palaces. See Class I. 2. 1. 15.

M. M. A bandage spread with plaster to cover the whole limb tight. Rags
dipped in a solution of sugar of lead. A warm flannel stocking or roller.
White lead and oak bark, both in fine powder. Horizontal rest.

15. _Scirrhus suppurans._ When a scirrhus affects any gland of no great
extent or sensibility, it is, after a long period of time, liable to
suppurate without inducing fever, like the indolent tumors of the
conglobate or lymphatic glands above mentioned; whence collections of
matter are often found after death both in men and other animals; as in the
liver of swine, which have been fed with the grounds of fermented mixtures
in the distilleries. Another termination of scirrhus is in cancer, as
described below. See Class I. 2. 3. 22.

16. _Carcinoma._ Cancer. When a schirrous tumor regains its sensibility by
nature, or by any accidental hurt, new vessels shoot amongst the yet
insensible parts of it, and a new secretion takes place of a very i
