M. M. The lancet is the anchor of hope in this disease; which must be
repeated four or five times, or as often as the fever and difficulty of
breathing increase, which is generally in the evening; antimonials,
diluents, repeated small blisters about the chest, mucilage, pediluvium,
warm bath. Is a decoction of seneka-root of use? Do not neutral salts
increase the tendency to cough by their stimulus, as they increase the heat
of urine in gonorrhoea? Children in every kind of difficult breathing, from
whatever cause, should be kept as upright in bed as may be, and continually
watched; since, if they slip down, they are liable to be immediately
suffocated. After the patient is greatly debilitated, so that no further
evacuation can be admitted, and the difficult breathing and cough continue,
I have given four or five drops of tincture of opium, that is, about a
quarter of a grain of solid opium, with great advantage, and I believe in
several cases I have saved the patient. A greater quantity of opium in this
state of debility cannot be used without hazarding the life of the person.
This small quantity of an opiate should be given about six in the evening,
or before the access of the evening paroxysm, and repeated three or four
nights, or longer.

There is a peripneumony with weak pulse, which may be termed _peripneumonia
inirritata_, as described in Sect. XXVII. 2. which belongs to this place.
See also Superficial Peripneumony, Class II. 1. 3. 7.

5. _Pleuritis._ Pleurisy. Inflammation of the pleura, with hard pulse, pain
chiefly of the side, pungent, particularly increased during inspiration;
lying on either side uneasy, the cough very painful, dry at the beginning,
afterwards moist, often bloody.

One cause of pleurisy is probably a previous adhesion of the lungs to a
part of the pleura, which envelops them. This in many cases has been
produced in infancy, by suffering children to lie too long on one side. Or
by placing them uniformly on one side of a fire, or window, to which they
will be liable always to bend themselves.

When matter is produced during peripneumony or pleurisy in one side of the
chest, so long as it is a concealed vomica, the fever continues, if the
disease be great, for many weeks, and even months; and requires occasional
venesection, till the patient sinks under the inflammatory or sensitive
irritated fever. But if air be admitted, by a part of the abscess opening
itself
