fected at the same time, and the torpor of the stomach
produces inirritative fever, and the mortification of the tonsils succeeds.

We may hence conclude, that when the torpor of the stomach is either owing
to defect of stimulus, which is not so great as to impair the life of the
part, as in moderate hunger, or in swallowing iced water, or when its
torpor is induced by its catenation or association with other torpid parts,
as in the commencement of intermittent fevers, and inoculated small-pox,
that the subsequent action of the heart and arteries is generally
increased, producing irritative fever. Which is owing to the accumulation,
of the sensorial power of irritation in one case, and of association in the
other, contributing to actuate the next link of the catenated or associated
motions. But when the torpor of the stomach is induced by previous
exhaustion of its sensorial powers of irritation or of association by
continued violent action, as by the stimulus of digitalis, or of contagious
matter, or after intoxication from wine or opium, a weaker action of the
heart and arteries succeeds, because there is no accumulation of sensorial
power, and a deficient excitement of association. And finally, as this weak
action of the heart and arteries is not induced by exhaustion of sensorial
power, but by defect of the excitement of association, the accumulation of
this power of association increases the action of the capillaries, and thus
induces inirritative fever.

7. When any part of the system acts very violently in fevers, the sensorial
power of sensation is excited, which increases the actions of the moving
system; whereas the pain, which arises from decreased irritative motions,
as in hemicrania, seems to exhaust a quantity of sensorial power, without
producing or increasing any fibrous actions.

When the stomach is primarily affected, as in inirritative fevers from
contagion, and in such a manner as to occasion pain, the action of the
capillaries seems to be increased by this additional sensorial power of
sensation, whence extensive inflammation or mortification; but when the
stomach and consequently the heart and arteries continue their torpidity of
action; as in confluent small-pox, and fatal scarlatina; this constitutes
sensitive inirritative fever, or typhus gravior.

But when the stomach is secondarily affected, if the sensorial power of
sensation is excited, as in pleurisy or peripneumony, the actions of the
he
