cooHng, the rising of the water from the
trough into the disengaging vessels, th6
tube of safety is employed. For the ex-
trication of ceases taking place in solu-
tions, for which no external heat is re-
quired, the bottle called disengaging bot-
tle, or proof, may be used. For receiv-
ers, to collect the disengaged airs, various
cylinders of glass are used, whether gra-
duated or not, either closed at one end.
or open at both ; and, in this last case,
Ihey are made air tight bv a stopper fitted
by grinding. Basides these, glass belU
and common bottles are employed.

To combine with water, in a commo-
dious way, some gases that are only gra-
dually and slowly absorbed by it, the glass
apparatus of Parker is serviceable.

A genus of disease in the class cachexite,

by a collection of air in the cellular tex-

pneumatosis are :

1. Pneitmatomt tpontanea, without any
manifest cause.

2. Pneumatotii traumatica, from a wound.

3. Pneumatosit venenata^ from poisons.

4. Pneumatosis hysterica, Vf\\h hysteria.

genus of disease in the class pyrexiit
and order phle^atia of Cullen; cha-
racterised by pyrexia, dlfiicult respira-
tion, cough, and a sense of weight and
pain in the thorax. The species of pneumo-
nia, according to the above nosologist, are»

1. Peripnemnoma. The pulse not al-
ways hard, but sometimes soft : an obtuse
pain in the breast : the respiration always
difficult ; sometimes the patient cannot
breathe, unless in an upright posture;
the face swelled, and of a livid colour;
the cough for the most part moist, fre-
quently bloody.

cough, dry in the beginning of the dite»»e»
aAerwM'ds moiit, and frequently bbodj.

With respect to pneomonia* the mott
general cauie of this inflammation^ is the
application of cold to the body, which

Sves a check to the perspiration, and de-
rmines a great flow of the blood to the
lungs. It attacks principally those of a
nobust constitution and plethoric habit,
«nd occurs most frequently in the winter
season and spring of the year i but it may
arise in either of the other seasons, when
there are sudden Ticissitudes from heat tp
cold.

Other causes, such as Tiolent exertions
jn singing, speaking, or playing on wind
instruments, by producing an increased
action of the lungs, ha?e oeen known to
occasion peripneumony. Those who have
laboured under a former attack of this
oomplaintf are much predisposed to returns
0f it.

The true peripneumony comes on with
an obtuse pam in the chest or side, great
difficulty of breathing, (particularly in a
recumbent position, or when lying on the
tide afTcctedy) together with a cough, dry-
ness of the skin, heat, anjiiety, and thirst
At the first commencement of the disease
the pulse is usually fuU^ strong, hard, and
frequent; but in a more advanced stage
it is commonly weak, soft, and often irre-
«lar. In tlie beginning, the cough is
ntquently dry and without expectoration ;
but in some cases it is moist even from the
iirst, and the matter spit up is various
both in colour and consistence, and is often
streaked with blood.

If relief is not afforded in time, and the
inflammation proceeds with such violence
as to endanger suffocation, the vessels of
the neck will become turgid and swelled ;
the face will alter to a purple colour ; an
effusion of blood will take place into the
cellular substance of the lungs, so as to
impede the circulation through that organ,
and the patient will soon be deprived of
life.

If these violent symptoms do not arise,
and the proper means for carrying off tlie
inflammation have either been neglected,
or have proved ineffectual, although adopt-
ed at an early period of the disease, a sup-
puration may ensue, which event is to be
known by frequent slight shiverings, and
an abatement of the pain and sense of ful-
ness In the part, and by the patient not
being able to lay on the side which was
affected, without experiencing great unea-
siness.

When peripneumony proves fatal, it is
generally by an effusion of blood taking
place into the cellular texture of the nings,
so atf to occasion suffocation, which usually
happens between the tliird and sevonth

terminating either in suppuration or gm-
grene.

When it goes off by resolutioa» sooie
verv evident evacuation always attends it;
such as a gceat flow of urine, with a co-
pious sediment, diarrfa^a^ a sweat diffoaed
over the whole body, or a haunorrhage
from the nose ; but the evacuation which
most frequently terminates the compUunt,
and which does it with the greatest effect,
is a free and copious expectoration ^
thick white or jrelluw matter, slightly
streaked with blood, snd by this the dis-
ease is carried of generally in xhp course
of ten or twelve days.

Our opinion as to the event, is to be
.drawn from the symptoms which are ptie-
sent. A high degree of fever, attended
with delirium, great difficulty of breath-
ing, acute pain, and dry cough, denote
great danger : on the contrary an abate-
ment of the febrile sjrmptoms, wad of the
difficulty of breathing, and pain, taking
place on the coming on of a free ex-
pectoration, or the happening of any other
•ritical evacuation, promises fair for the
recovery of the patient. A termination
of the infianunation in suppuration, is al-
vays to be considered as dangerous.

On dissection, the lungs usually appear
inflamed, and there is onen found an ex-
travasation, either of blood, or of coagu-
lable lymph in their cellular substance.
The same appearances likewise present
themselves in the cavity of the thorax and
within the pericardium. The pkura, con-
nected with the lungs, is also ^n an in-
flamed state, having its surface every
where crowded with red vessels. Be-
sides these, abscesses are frequently found
in the substance of the lungs, as like-
wise tubercles and adhesions to the rihs
are formed. A quantity of purulent mat^
ter is often discovered also in the bron-
chi ae.
