hich circumstance deserves further attention.

Another way of immediately stimulating the heart and arteries would be by
transfusing new blood into them. Is it possible that any other fluid
besides blood, as chyle, or milk, or water, could, if managed with great
art, be introduced safely or advantageously into the vein of a living
animal?

A third method of exciting the heart and arteries immediately is by
increasing the natural stimulus of the blood, and is well worthy experiment
in all fevers with weak pulse; and that consists in supplying the blood
with a greater proportion of oxygen; which may be done by respiration, if
the patient was to breathe either oxygen gas pure, or diluted with
atmospheric air, which might be given to many gallons frequently in a day,
and by passing through the moist membranes of the lungs, according to the
experiments of Dr. Priestley, and uniting with the blood, might render it
more stimulant, and thus excite the heart and arteries into greater action!
May not some easier method of exhibiting oxygen gas by respiration be
discovered, as by using very small quantities of hyper-oxygenated marine
acid gas very much diluted with atmospheric air?

XII. _Torpor of the Stomach and upper Intestines._

1. The principal circumstance, which supports the increased action of the
capillaries in continued fever with weak pulse, is their reverse sympathy
with those of the stomach and upper intestines, or with those of the heart
and arteries. The torpor of the stomach and upper intestines is apparent in
continued fevers from the total want of appetite for solid food, besides
the sickness with which fevers generally commence, and the frequent
diarrhoea with indigested stools, at the same time the thirst of the
patient is sometimes urgent at the intervals of the sickness. Why the
stomach can at this time take fluids by intervals, and not solids, is
difficult to explain; except it be supposed, as some have affirmed, that
the lacteal absorbents are a different branch from the lymphatic
absorbents, and that in this case the former only are in a state of
permanent torpor.

2. The torpor of the heart and arteries is known by the weakness of the
pulse. When the actions of the absorbents of the stomach are diminished by
the exhibition of small doses of digitalis, or become retrograde by larger
ones, the heart and arteries act more feebly by direct sympathy; but the
cellular, cutaneous, and pulmonary absorbents a
