in eight days
from the first application of the caustic the hand was quite well.

3. _Of Fungous Ulcer of the Navel in Infants._

It sometimes occurs that a little fungous sore exists upon the navel
in infants which is difficult of cure in the ordinary way. I had one
case which had subsisted for two years, and another, which had
continued for two months, and were, during those periods, a source of
great trouble and uneasiness to the mothers of the little patients.
These ulcers are easily cured in the following manner.

The fungus is to be completely removed by a pair of scissors, and when
the bleeding has quite ceased, the lunar caustic is to be applied,
and the part defended by the gold-beater's skin and kept carefully
from any moisture.

In one of the cases mentioned above the eschar was accidentally
separated twice and required to be renewed; but both cases were cured
in the space of a few days.

4. _Of Inflammation of the Knee._

Servant women, I suspect from much kneeling in scouring stairs, &c.
are subject to a species of inflammation of the knee which is
frequently extremely troublesome.

In one case suppuration of the integuments took place in the forepart
of the knee, and the patient was obliged to leave her situation and go
to her friends at a distance, although every antiphlogistic means was
tried for her relief.

In two other cases, after the application of twenty leeches and the
administration of an emetic and purgative medicine, I applied the
lunar caustic freely over the whole surface of the knee previously
moistened with water. In a few hours the cuticle was raised and
vesicated; I evacuated a viscid puriform fluid, and I directed the
constant application of the cold poultice and lotion.

In a few days all inflammation subsided and the patients remained
well.

These three cases having occurred to me at the same time, and being
apparently equally severe, I was enabled to judge of the efficacy of
this use of the caustic, and I can strongly recommend it to a future
and further trial. Its application causes more pain than a blister,
but not so much as to form an obstacle to its employment.

It may not be unimportant, here, to suggest the trial of the caustic
in other cases of inflammation, in which a more than usually active
local remedy is required.

5. _Of Tinea Capitis, &c._

In this place I have only to observe that I have in some cases
completely succeeded, in others completely
