equent greater associability; which is now also more strongly excited
by the increased actions of the capillaries. And thus a fit of simple fever
is produced, which is termed Febris irritativa; and consists of a torpor of
the cutaneous capillaries with their mucous and perspirative glands,
accompanied with a torpor of the heart and arteries; and afterwards of an
increased action of all these vessels, by what is termed direct sympathy.

This fever, with strong pulse without inflammation, or febris irritativa,
described in Class I. 1. 1. 1. is frequently seen in vernal intermittents,
as the orgasm of the heart and arteries is then occasioned by their
previous state of torpor; but more rarely I believe exists in the type of
continued fever, except there be an evident remission, or approximation to
a cold fit; at which time a new accumulation of the sensorial power of
association is produced; which afterwards actuates the heart and arteries
with unnatural vigour; or unless there be some stimulus perpetually acting
on the system so as to induce an increased secretion of sensorial power in
the brain, as occurs in slight degrees of intoxication. Since without one
or other of these circumstances in continued fevers without inflammation,
that is, without the additional sensorial power of sensation being
introduced, it seems difficult to account for the production of so great a
quantity of sensorial power, as must be necessary to give perpetual
increase of action to the whole sanguiferous system.

3. On the contrary, while the cutaneous capillaries with their mucous and
perspirative glands acquire an increased irritability, as above, by the
accumulation of that sensorial power during their previous quiescence, and
thus constitute the hot fit of fever; if the heart and arteries do not
acquire any increase of associability, but continue in their state of
torpor, another kind of simple fever is produced; which is generally of the
continued kind, and is termed Febris inirritativa; which consists of a
previous torpor of the capillaries of the skin, and of the heart and
arteries by direct sympathy with them; and afterwards of an orgasm or
increased action of the capillaries of the skin, with a decreased action,
or continued torpor, of the heart and arteries by reverse sympathy with
them. This orgasm of the cutaneous capillaries, which appears by the blush
and heat of the skin, is at first owing to the accumulation of the
sensorial power
