In the healthy living Body the BALANCE of
Principles is conftantly kept up by the Sur-

When the Balance gets broken, a lofs of
HEALTH, OF DEATH, enfues,
When an Animal is bit by a VIPER, with
the Lofs of IRRITABILITY, there is a De-
ftruction of the RIGHT BALANCE of the
Principles of the Body, -

The Blood diffolved and partly coagulated,
from being red becomes black or brown,
From being a bland Fluid contained within
numerous Veffels, it becomes a perfect Cauf-
tic, corrupting and decompofing whatever
it meets with,
{T
The PART BITTEN goes into immediate Putre-
faction,
{The SKIN becomes fpeedily livid,
{And the MUSCLES become black and fœtid,
But the moft remarkable Change is in the
LUNGS, which is filled with black Blood,
and exhibits every where livid Spots,-
This black Appearance, especially in the
Lungs, would lead one to fuppose, that
the OXYGEN of the Blood, which we have
before fhewn gives it its crimson Colour, had entered into fome new State of Com- bination, and with it, the IRRITABLE PRIN- CIPLE itself was fled,

Equal Quantities of Blood were put into the
fame Veffels, and equally agitated,
In the one three Drops of VENOM was re-
ceived, and in two Minutes, the Blood in
the Veffel containing no Venom coagulated,
and affumed a fine vermilion Colour, where-
as in the other it remained black and
fluid,
It is the fame with the VEGETABLE POI-
SONS,
About a Quarter of a Drop of a Solution of
the TICUNAS being injected into the Jugu-
lar Vein of a Rabbit, it instantly dropped
down dead,
1. The whole BODY became pliant and relaxed,
2. The BLOOD was fluid, and in the
venous Veffels near the Heart darker
than usual,
3. The MUSCLES were remarkably pale,
4. The Lungs were covered with large
and livid Spots.
This Change in fo noble an Organ de-
ferves the utmost Attention.

nearly the fame with refpect to the
Venom of the Viper,
A COMPARISON made betwixt the Poison of
the Viper and the Ticunas, -
A ftrong Proof, of the Tenacity of Life in the Viper and Adder, and of the fuperior Power of the Ticunas,
Four Drops of an aqueous Solution of the TI-
CUNAS being put into a Veffel contain-
ing fome fresh Blood, it did not coagulate,
and affumed a dark Colour,

This Poifon was next tried in Parts devoid of
Irritability, as
1. On the TENDON of a Mufcle,
2. On the NERVES,
Here the Ticunas agrees with the Venom of
the Viper in being quite INNOCENT When
applied to either TENDON or NERVE,
The Nerve was feparated going to the
Thigh, but the Venom applied to the Muf-
cle of the Leg, nevertheless extended its
influence over that Limb to the Rest of the
Body, -

{These are overcome by actual Experiments.
A Frog being put into Azotic Air, the Ani-

1. The BODY was flaccid and relaxed, - ib.
2. The HEART, as well as all the other MUSCLES, were inirritable, -
3. The Colour of the Red BLOOD was

Two Frogs being put into Nitrous Gas, they
almost instantly died, and,

4. On pricking the CRURAL NERVES,
the Leg remained motionless, -
Some Azotic Air being injected into the Ju-
gular Vein of a Dog, the Animal
died, -
1. The BLOOD was found of a black
Colour on the right and left Sides of
the Heart,
2. The HEART and all the MUSCLES had
loft their Irritability,
Some Fixed Air being injected into the Jugu-
lar Vein of a Dog, the Animal died,
1. The RIGHT AURICLE and VEN-
TRICLE were filled with dark Blood,
2. The Blood contained in the LEFT
VENTRICLE and AURICLE was of a
deeper Colour than ordinary, -
3. The HEART and MUSCLES had loft
all their Irritability,
