becomes intoxicated by eating a few
mushrooms of a peculiar kind, a general alarm is excited, and he is said to
be poisoned, and emetics are exhibited; but so familiarised are we to the
intoxication from vinous spirit, that it occasions laughter rather than
alarm.

There is however considerable danger in too hastily discontinuing the use
of so strong a stimulus, lest the torpor of the system, or paralysis,
should sooner be induced by the omission than by the continuance of this
habit, when unfortunately acquired. A golden rule for determining the
quantity, which may with safety be discontinued, is delivered in Sect. XII.
7. 8.

11. Definition of drunkenness. Many of the irritative motions are much
increased in energy by internal stimulation.

2. A great additional quantity of pleasurable sensation is occasioned by
this increased exertion of the irritative motions. And many sensitive
motions are produced in consequence of this increased sensation.

3. The associated trains and tribes of motions, catenated with the
increased irritative and sensitive motions, are disturbed, and proceed in
confusion.

4. The faculty of volition is gradually impaired, whence proceeds the
instability of locomotion, inaccuracy of perception, and inconsistency of
ideas; and is at length totally suspended, and a temporary apoplexy
succeeds.

SECT. XXII.

OF PROPENSITY TO MOTION, REPETITION AND IMITATION.

I. _Accumulation of sensorial power in hemiplagia, in sleep, in cold
fit of fever, in the locomotive muscles, in the organs of sense.
Produces propensity to action._ II. _Repetition by three sensorial
powers. In rhimes and alliterations, in music, dancing, architecture,
landscape-painting, beauty._ III. 1. _Perception consists in imitation.
Four kinds of imitation._ 2. _Voluntary. Dogs taught to dance._ 3.
_Sensitive. Hence sympathy, and all our virtues. Contagious matter of
venereal ulcers, of hydrophobia, of jail-fever, of small-pox, produced
by imitation, and the sex of the embryon._ 4. _Irritative imitation._
5. _Imitations resolvable into associations._

I. 1. In the hemiplagia, when the limbs on one side have lost their power
of voluntary motion, the patient is for many days perpetually employed in
moving those of the other. 2. When the voluntary power is suspended during
sleep, there commences a ceaseless flow of sensitive motions, or ideas of
