eparation of the eschars, I found the healing
process going on. I reapplied the lunar caustic to form eschars, and I
evacuated a little fluid from their centre for three successive days.

At this time the patient took cold and a smart attack of fever came
on, and the part round the eschars became much inflamed. I prescribed
an emetic and purge, and a cold poultice and lotion.

In the space of a week I again attempted to form an eschar over the
larger wound, for the smaller one had quite healed.

The next day I discharged a little fluid from the centre, and again on
the eight or nine succeeding days, giving saline purgatives.

After this time the eschar remained adherent, and no further remedy
was required.

This case is particularly interesting and important, as it illustrates
the plans to be adopted in two circumstances of no unfrequent
occurrence; 1. when there is an attack of fever and increased
inflammation, and 2. when a scab forms underneath the eschar. In both
cases we must relinquish our attempt to form an adherent eschar for a
time,--apply the poultice,--and recur to the caustic in the course of
a few days.

In the beginning of my trials of the treatment of the ulcers by the
caustic, I was repeatedly betrayed by the smooth appearance of the
eschar, to think that all was going on well, when in fact a scab was
all along forming underneath. In these cases inflammation soon
followed, and it was only by carefully and daily evacuating the fluid
effused under the eschar that I at length succeeded in effecting an
adherent eschar free from surrounding inflammation. This remark cannot
be too often repeated.

CASE XXIX.

The peculiarity of the present case arose from neglect in evacuating
the fluid effused under the eschar the day succeeding its formation,
the consequence of which was that the edges of the eschar became
raised all round, without however being entirely detached.

Mr. Draper, aged 50, had a small irritable ulcer of the size of a
horse-bean, upon the shin, of a month's duration, with surrounding
inflammation to the extent of several inches. I applied the lunar
caustic to form an eschar and protected it with gold-beater's skin.

On the following day, it appeared from the flatness of the surface,
that the eschar was adherent; the inflammation remained as before.

On the next day the eschar was raised all round its borders,
presenting the appearance of an elevated ring. I made an opening in
one
