torpor occurs.

When the hot fit approaches, the stomach in fevers with strong pulse
regains its activity by the accumulation of the sensorial power of either
irritation, if it was the part first affected, or of association if it was
affected in sympathy with some other torpid part, as the spleen or liver;
which accumulation is produced during its torpor. At the same time all the
other parts of the system acquire greater energy of action by the
accumulation of the sensorial power of association, which was produced,
during their inactivity in the cold fit.

But in fevers with weak pulse the stomach, whose sensorial power of
irritation had been previously exhausted by violent action, acquires no
such quick accumulation of sensorial power, but remains in a state of
torpor after the hot fit commences. The heart and arteries remain also in a
state of torpor, because there continues to be no excitement of their power
of association owing to the torpid motions of the stomach; but hence it
happens, that there exists at this time a great accumulation of the power
of association in the less active fibres of the heart and arteries; which,
as it is not excited and expended by them, increases the associability of
the next link of the associated chain of motions, which consists of the
capillaries or other glands; and that in so great a degree as to actuate
them with unnatural energy, and thus to produce a perpetual hot fit of
fever. Because the associability of the capillaries is so much increased by
the accumulation of this power, owing to the lessened activity of the heart
and arteries, as to over-balance the lessened excitement of it by the
weaker movements of the heart and arteries.

6. When the accumulation of the sensorial power of irritation caused by
defect of stimulus is greater in the first link of a train of actions, to
which associated motions are catenated, than the deficiency of the
excitement of the sensorial power of association in the next link, what
happens?--the superabundance of the unemployed sensorial power of the first
link is derived to the second; the associability of which thus becomes so
greatly increased, that it acts more violently than natural, though the
excitement of its power of association by the lessened action of the first
link is less than natural. So that in this situation the withdrawing of an
accustomed stimulus in some parts of the system will decrease the
irritative motions of that part, an
