rs had separated
from the smallest ulcers leaving the parts healed.

In a day or two more, my patient took cold and was affected with
hoarseness and cough, and the skin round the eschar became excoriated
a little. I directed a saline purgative and applied the lunar caustic
to the excoriated parts.

On the succeeding day his cold was better and the eschars adherent. I
directed five grains of the Plummer's pill to be taken night and
morning, which he continued about a week.

Five days after this period, I again observed a disposition to
excoriate. I applied the caustic.

In two days more, the eschars were adherent, and there was no further
appearance of excoriation.

In ten more days, the eschars had separated and all the ulcers and
excoriations were completely healed.

This case occurred several years ago, and there has been no return of
the affliction whatever.

CASE XXIII.

Mr. Marshall, aged 60, had a troublesome ulcer under the outer ankle,
of an oblong form and of the size of sixpence. He has been long
subject to ulcers of the legs, and he had a similar ulcer to the
present one in the same situation, some years ago, which proved
extremely difficult to heal under usual remedies. The veins are
varicose.--From the small size of the ulcer, I applied the lunar
caustic and protected the eschar by the gold-beater's skin.

On the following day, I found the eschar complete but unadherent by
the effusion of a little fluid; this I evacuated daily in the manner
already described, for about a fortnight, when the eschar became
adherent.

During the progress of the cure a little excoriation formed round the
eschar. I touched the parts with the caustic, and the eschar thus
formed served to support that formerly made, and so to do good. The
whole adhered until the sore was very nearly healed; but as it was
situated in a part greatly exposed, it was removed by accident. The
caustic was again applied; fluid formed underneath the eschar as
before and required evacuating thrice; but at length the eschar
adhered, and in due time separated leaving the ulcer quite healed.

The same patient has since been affected by similar ulcers at
different times in different parts of the leg. He applied early and
they were each time easily cured by one application of the caustic. He
has also twice had injuries upon the shin, which were readily cured in
the same manner.

CASE XXIV.

The following case must not be regarded as altog
