IF SUCH HAS BEEN THE PROGRESS OF THIS
INSTITUTION IN ITS EARLY STAGES,
WHAT MAY NOT BE EXPECTED, NOW
THAT PHILOSOPHY HOLDS UP THE
TORCH TO MEDICINE, TO ILLUMINE ITS
VOTARIES, AND DIRECT THEIR COURSE
IN THIS NEW PATH OF SCIENCE!

A SCIENCE NO LESS DIFFICULT, THAN IT IS
SUBLIME AND IMPORTANT; INVOLVING
AT ONCE THE MOST INTRICATE PROBLEMS,
IN PHYSIOLOGY, PATHOLOGY, CHEMISTRY,
AND PNEUMATIC PHILOSOPHY !

CALCULATED NOT LESS TO EXERCISE THE
KEENEST FACULTIES OF THE HEAD, THAN
TO INTEREST THE FINEST FEELINGS OF
THE HEART!

SECT. XLVII. JOHN HUNTER'S PROPOSALS
FOR THE RECOVERY OF Drowned

PERSONS.

{

He confiders DROWNING as a Sufpenfion only
of the Actions of Life,

This Ceffation of Motion of the Heart he attri-
butes to the Lofs of Refpiration, which
needs only to be reftored in Time, and all
the other Actions of Life are as inftantly
renewed,

This Reasoning is enforced by the falutary
Effects of AIR on ftill-born Infants,

JOHN HUNTER'S CELEBRATED Experiment.

He contrived a pair of Bellows so as to imi-
tate by its twofold Action Respiration,

ib.

{The

The Muzzle of thefe Bellows he fixed in the
Windpipe of a Dog,

563

{

He removed the Sternum fo as to expofe to
View the Heart and Lungs,

When he ceafed to force AIR into the Lungs
the Action of the Heart became gradually
weaker, till it left off moving altogether, ib.

But

ib.

But by renewing the ARTIFICIAL BREATH-
ING its Contraction returned, as frequent and
as ftrong as ever,

JOHN HUNTER obferved, that the Blood on
the left Side, when AIR was not injected
into the Lungs, became as BLACK as
that in the right Side,

Or, in other Words, that both Sides of the
Heart had the SAME COLOURED
BLOOD,

This Situation of the Animal he confiders as

ib.

1. That an Animal poffeffes often the
POWER when deprived of the Ac-
TION of Life.

2. That the LIVING PRINCIPLE is in-
herent in the Blood.

3. That the Stomach fympathizes with
every Part of an Animal, and that

every Part fympathizes with the Sto-
mach, -

AS SOON AFTER IMMERSION AS POS-
SIBLE AIR SHOULD BE FORCED INTO
THE LUNGS.

VITAL AIR would produce a more certain and
immediate Effect, -

Whatever Philofopher, fays this great Anatomift, fhall hereafter inveftigate the Operation of Air in the animal Economy, and will purfue my Ideas of the Vitality of the Blood, he will become a Benefactor to Mankind, and his Name will be immortal, 565

The Heart is set in motion by the Stimulus of VITAL AIR, which the Blood absorbs in its paffage through the Lungs,

566

This abforbed Air gives the Blood its FLORID
COLOUR, and is the Source of ANIMAL
HEAT,

ib.

Hence we learn, when deprived of THIS
AIR, why

1. The Countenance and Lips grow
LIVID, and

2. The Body lofes its NATURAL HEAT, - 567

The primary Object therefore in the Sufpen

fion of VITAL ACTION is to institute arti-
ficial Refpiration,

{The PUREST AIR ought to be employed,

{This is proved by actual Experiments,

FIRST INFLATED THE LUNgs, if Re-

COVERY DOES NOT IMMEDIATELY SUC

CEED, TO APPLY VOLATILE SALTS TO
THE NOSTRILS.

refpiratory Organs,

Several curious Experiments wherein the Effi-
cacy of ELECTRICITY is demonftrated,
