t the same time
excited less powerfully than usual by the sensorial power of association.
Thus the accumulation of the sensorial power of irritation in the vessels
of the skin increases in this case the action of the stomach, in the same
manner as an accumulation of the sensorial power of association in the
heart and arteries in fevers with weak pulse increases the action of the
capillaries.

If nevertheless the coldness of the skin be too long continued, or exists
in too great a degree, so as in some measure to impair the life of the
part, no further accumulation of the sensorial power of irritation occurs;
and in consequence the actions of the stomach become less than natural by
the defect of the sensorial power of association; which has ceased to be
excited by the want of action of the cutaneous capillaries. Whence
continued coldness of the feet is accompanied with indigestion and
heartburn. See Class IV. 2. 1. 6.

6. Similar to this when the actions of the stomach are rendered torpid by
the previous stimulus of a violent emetic, and its motions become
retrograde in consequence, a great quantity of sensorial power is exerted
on the lymphatics of the lungs, and other parts of the body; which excites
them into greater direct action, as is evinced by the exhibition of
digitalis in anasarca. In this situation I suppose the emetic drug
stimulates the muscular fibres of the stomach into too great action; and
that in consequence a great torpor soon succeeds; and that this inaction of
the muscular parts of the stomach is not followed by much accumulation of
the sensorial power of irritation; because that sensorial power is in great
measure exhausted by the previous excessive stimulus. But the lymphatics of
the stomach have their actions lessened by defect of the sensorial power of
association, which is not now excited into action, owing to the lessened
motions of the muscular parts of it, with which the lymphatics are
associated. The sensorial power of association becomes therefore
accumulated in these lymphatics of the stomach, because it is not excited
into action; exactly as the power of irritation becomes accumulated in the
hand, when immersed in snow; and this accumulated sensorial power of
association excites the lymphatic of the lungs and of other parts, which
are most nearly associated with those of the stomach, into more energetic
actions. Thus the muscular fibres of the stomach act with the lymphatics of
that orga
