irritates the ureter, and that
even without its being attended with pain or fever, sometimes a chronical
hiccough occurs, and continues for days and weeks, instead of sickness or
vomiting; which are the common symptoms. In this case the motions of the
stomach are decreased by their sympathy with those of the ureter, which are
increased by the stimulus of the stone in it; and the increased motions of
the diaphragm seem to exist in consequence of their association with the
stomach by a second reverse sympathy. This hiccough may nevertheless admit
of another explanation, and be supposed to be a convulsive exertion of the
diaphragm to relieve the disagreeable sensation of the stomach in
consequence of its disordered irritative associations; and in that case it
would belong to Class III. 1. 1. See Class IV. 2. 1. for another example of
tertiary association.

M. M. Venesection. Emetic. Calomel. Cathartic, opium, oil of cinnamon from
two to ten drops. Aerated alcaline water. Peruvian bark.

8. _Febris irritativa._ Irritative fever, described in Class I. 1. 1. 1.
The diseases above explained in this genus are chiefly concerning the
sympathies of the absorbent system, or the alimentary canal, which are not
so much associated with the arterial system, as to throw it into disorder,
when they are slightly deranged; but when any great congeries of
conglomerate glands, which may be considered as the extremities of the
arterial system, are affected with torpor, the whole arterial system and
the heart sympathize with the torpid glands, and act with less energy;
which constitutes the cold fit of fever; which is therefore at first a
decreased action of the associate organ; but as this decrease of action is
only a temporary effect, and an increase of exertion both of the torpid
glands, and of the whole arterial system, soon follows; the hot fit of
irritative fever, or fever with strong pulse, properly belongs to this
class and genus of diseases.

_Increased Associate Motions._

GENUS II.

_Catenated with Sensitive Motions._

The primary links of the associated actions of this genus are either
produced or attended by painful or pleasurable sensation. The secondary
links of the first ten species are attended with increased motions without
inflammation, those of the remainder are attended with inflammation. All
inflammations, which do not arise in the part which was previously torp
