nce I conclude,
that our nerves of sense are not torpid or inert during sleep; but that
they are only precluded from the perception of external objects, by their
external organs being rendered unfit to transmit to them the appulses of
external bodies, during the suspension of the power of volition; thus the
eye-lids are closed in sleep, and I suppose the tympanum of the car is
not stretched, because they are deprived of the voluntary exertions of
the muscles appropriated to these purposes; and it is probable something
similar happens to the external apparatus of our other organs of sense,
which may render them unfit for their office of perception during sleep:
for milk put into the mouths of sleeping babes occasions them to swallow
and suck; and, if the eye-lid is a little opened in the day-light by the
exertions of disturbed sleep, the person dreams of being much dazzled.

Rolls in their marble orbs his Gorgon-eyes,
And drinks with leathern ears her tender cries.

Arm'd with her ivory beak, and talon-hands,

Chamber'd in earth with cold oblivion lies;
Nor heeds, _ye Suitor-train_, your amorous sighs;
Erewhile with renovated beauty blooms,
Mounts into air, and moves her leafy plumes.

Each in his flinty channel winds along;
With lucid lines the dusky Moor divides,
Hurrying to intermix their sister tides.

[When there arises in sleep a painful desire to exert the voluntary
motions, it is called the Nightmare or Incubus. When the sleep becomes so
imperfect that some muscular motions obey this exertion of desire, people
have walked about, and even performed some domestic offices in sleep;
one of these sleep-walkers I have frequently seen: once she smelt of a
tube-rose, and sung, and drank a dish of tea in this state; her awaking
was always attended with prodigious surprize, and even fear; this disease
had daily periods, and seemed to be of the epileptic kind.]

tree rises with opposite branches on all sides, with long egged leaves;
each branch emits a slender flexile depending appendage from its summit
like a cord, which roots into the earth and rises again. Sloan. Hist. of
