hich
is also sometimes accompanied with great flow of urine, owing to the
defective absorption of its aqueous parts; and with consequent thirst
occasioned by the want of so much fluid being returned into the
circulation; a lodgment of faeces in the rectum sometimes occurs after this
complaint from the lessened sensibility of it. See Class I. 2. 4. 15.

M. M. Venesection; gentle cathartics; diluents; fomentation; poultice with
camomile flowers, turpentine, soap, and opium; afterwards the bark. See
Class I. 1. 3. 5.

When this inflammation terminates in suppuration the matter generally can
be felt to fluctuate in the groin, or near the top of the thigh. In this
circumstance, my friend Mr. Bent, Surgeon near Newcastle in Staffordshire,
proposes to tap the abscess by means of a trocar, and thus as often as
necessary to discharge the matter without admitting the air. Might a weak
injection of wine and water, as in the hydrocele, be used with great
caution to inflame the walls of the abscess, and cause them to unite? See
Class II. 1. 6. 9.

19. _Paronychia interna._ Inflammation beneath the finger-nail. The pain
occasioned by the inflammatory action and tumor of parts bound down between
the nail on one side and the bone on the other, neither of which will
yield, is said to occasion so much pain as to produce immediate delirium,
and even death, except the parts are divided by a deep incision; which must
pass quite through the periosteum, as the inflammation is said generally to
exist beneath it. This disease is thus resembled by the process of toothing
in young children; where an extraneous body lodged beneath the periosteum
induces pain and fever, and sometimes delirium, and requires to be set at
liberty, by the lancet.

GENUS III.

_With the Production of new Vessels by external Membranes or Glands with
Fever._

The diseases of this genus are perhaps all productive of contagious matter;
or which becomes so by its exposure to the air, either through the cuticle,
or by immediate contact with it; such are the matters of the small-pox and
measles. The purulent matter formed on parts covered from the air by
thicker membranes or muscles, as in the preceding genus, does not induce
fever, and cannot therefore be called contagious; but it acquires this
property of producing fever in a few hours, after the abscess has been
opened, so as to admit the
