ermentation of the aliment
proceeds the faster; for stopping the vessels, which contain new wines,
retards their fermentation, and opening them again accelerates it; hence
where the digestion is impaired, and the stomach somewhat distended with
air, it is better to restrain than to encourage eructations, except the
quantity makes it necessary. When wine is confined in bottles the
fermentation still proceeds slowly even for years, till all the sugar is
converted into spirit; but in the process of digestion, the saccharine part
is absorbed in the form of chyle by the bibulous mouths of the numerous
lacteals, before it has time to run into the vinous fermentation.

3. _Apepsia._ Indigestion. Water-qualm. A few mouthfuls of the aliment are
rejected at a time for some hours after meals. When the aliment has had
time to ferment, and become acid, it produces cardialgia, or heart-burn.
This disease is perhaps generally left after a slight inflammation of the
stomach, called a surfeit, occasioned by drinking cold liquors, or eating
cold vegetables, when heated with exercise. This inflammation of the
stomach is frequently, I believe, at its commencement removed by a critical
eruption on the face, which differs in its appearance as well as in its
cause from the gutta rosea of drunkards, as the skin round the base of each
eruption is less inflamed. See Class II. 1. 4. 6.. This disease differs
from Cardialgia, Class I. 2. 4. 5. in its being not uniformly attended with
pain of the cardia ventriculi, and from its retrograde motions of a part of
the stomach about the upper orifice of it. In the same manner as hysteria
differs from hypochondriasis; the one consisting in the weakness and
indigestion of the same portions of the alimentary canal, and the other in
the inverted motions of some parts of it. This apepsia or water-qualm
continues many years, even to old age; Mr. G---- of Lichfield suffered
under this disease from his infancy; and, as he grew old, found relief only
from repeated doses of opium.

M. M. A blister, rhubarb, a grain of opium twice a day. Soap, iron-powder.
Tin-powder.

4. _Vomitus._ An inverted order of the motions of the stomach and
oesophagus with their absorbent vessels, by which their contents are
evacuated. In the act of vomiting less sensorial power is employed than in
the usual peristaltic motion of the stomach, as explained in Sect. XXXV. 1.
