s the capillaries of the skin; that
there is a deficiency for the purposes of the other irritative associations
of motions usually connected with it. This auditory vertigo attends both
the rotatory and the visual vertigo above mentioned; in the former it is
introduced by reverse sympathy, that is, by the diminution of sensorial
power; too great a quantity of it being expended on the increased
irritative motions of vision; in the latter it is produced either by the
same causes which produce the visual vertigo, or by direct sympathy with
it. See Sect. XX. 7.

M. M. Stimulate the internal ear by ether, or with essential oil diluted
with expressed oil, or with a solution of opium in wine, or in water. Or
with salt and water.

16. _Tactus, gustus, olfactius vertiginosi._ Vertiginous touch, taste, and
smell. In the vertigo of intoxication, when the patient lies down in bed,
it sometimes happens even in the dark, that the bed seems to librate under
him, and he is afraid of falling out of it. The same occurs to people, who
are sea-sick, even when they lie down in the dark. In these the irritative
motions of the nerves of touch, or irritative tangible ideas, are performed
with less energy, in one case by reverse sympathy with the stomach, in the
other by reverse sympathy with the nerves of vision, and in consequence
become attended with sensation, and produce the fear of falling by other
associations.

A vertigo of the sense of touch may be produced, if any one turns round for
a time with his eyes shut, and suddenly stops without opening them; for he
will for a time seem to be still going forwards; which is difficult to
explain. See the notes at the end of the first and second volume belonging
to Sect. XX. 6.

In the beginning of some fevers, along with incessant vomiting, the
patients complain of disagreeable tastes in their mouth, and disagreeable
odours; which are to be ascribed to the general debility of the great
trains and tribes of associated irritative motions, and to be explained
from their direct sympathy with the decreased action of a sick stomach; or
from the less secretion of sensorial power in the brain. These organs of
sense are constantly stimulated into action by the saliva or by the air;
hence, like the sense of hunger, when they are torpid from want of
stimulus, or from want of sensorial power, pain or disagreeable sensation
ensues, as of hunger, or faintness, or sickness in one case; and the ideas
of bad
