se sympathy, with which the absorbent vessels of the
stomach and upper intestines act in respect to all the other absorbent
vessels, as in the exhibition of digitalis, and in ileus; there is another
reverse sympathy exists between the capillaries, or secretory vessels of
the stomach, and those of the skin. Which may nevertheless be occasioned by
the accumulation of sensorial power by the torpor of the heart and
arteries, which is induced by direct sympathy with the stomach; thus when
the torpor of the stomach remains in a fever-fit which might otherwise have
intermitted, the torpor of the heart and arteries remains also by direct
sympathy, and the increased cutaneous capillary action, and consequent
heat, are produced by reverse sympathy; and the fever is thus rendered
continual, owing primarily to the torpor of the stomach.
6. The reverse sympathy, which exists between the capillaries of the
stomach and the cutaneous capillaries, appears by the chillness of some
people after dinner; and contrary-wise by the digestion being strengthened,
when the skin is exposed to cold air for a short time; as mentioned in
Class IV. 1. 1. 4. and IV. 2. 1. 1. and from the heat and glow on the skin,
which attends the action of vomiting; for though when sickness first
commences, the skin is pale and cold; as it then partakes of the general
torpor, which induces the sickness; yet after the vomiting has continued
some minutes, so that an accumulation of sensorial power exists in the
capillaries of the stomach, and of the skin, owing to their diminished
action; a glow of the skin succeeds, with sweat, as well as with increased
absorption.
7. Nevertheless in some circumstances the stomach and the heart and
arteries seem to act by direct sympathy with the cutaneous capillaries, as
in the flushing of the face and glow of the skin of some people after
dinner; and as in fevers with strong pulse. In these cases there appears to
be an increased production of sensorial power, either of sensation, as in
the blush of shame; or of volition, as in the blush of anger; or of
irritation, as in the flushed face after dinner above mentioned.
This increased action of the capillaries of the skin along with the
increased actions of the stomach and heart is perhaps to be esteemed a
synchronous increase of action, rather than a sympathy between those
organs. Thus the flushing of the face after dinner may be owing to the
secretion of sensorial power in the bra
