tely keeping their fingers on
the orifice, and afterwards by a long bandage of broad tape.

2. _Pterigion._ Eye-wing. A spot of inflammation sometimes begins on the
inside of the lower eyelid, or on the tunica albuginea, and spreads an
intertexture of red vessels from it, as from a center, which extend on the
white part of the eye, and have the appearance of the wing of a fly, from
whence its name.

M. M. Cut the ramifications of vessels again and again with the point of a
lancet close to the center of inflammation.

3. _Tarsitis palpebrarum._ Inflammation of the edges of the eyelids. This
is a disease of the glands, which produce the hairs of the eye-lashes, and
is frequently the cause of their falling off. After this inflammation a
hard scar-like ridge is left on the edge of the eyelid, which scratches and
inflames the eyeball, and becomes a very troublesome disease.

The Turkish ladies are said to colour the edge of the eyelash with crude
antimony in very fine powder, which not only gives lustre to the eye, as a
diamond set on a black soil, but may prevent extraneous light from being
reflected from these edges into the eye, and thus serve the purpose of the
black feathers about the eyes of swans, described in Sect. XXXIX. 5. 1. and
may also prevent the edges of the eyelids from being inflamed by the
frequent stimulus of tears on them. Black lead in fine powder might be
better for all these purposes than antimony, and might be put on with a
camel's hair brush.

M. M. Mercurial ointment smeared at night on the edges of the eyelids.
Burnt alum sixty grains, hog's grease half an ounce, well rubbed into an
ointment to be smeared on them in the night. Cold water frequently in the
day. See Class II. 1. 1. 8.

4. _Hordeolum._ Stye. This inflammation begins either on or near the edges
of the eyelids, or in the loose skin of them, and is sometimes very slow
either in coming to suppuration or in dispersing. The skin beneath the
lower eyelid is the most frequent seat of this tumor, which sometimes never
suppurates at all, but becomes an incysted tumor: for as this skin is very
loose for the purpose of admitting great motion to the eyelid, the
absorbent power of the veins seems particularly weak in this part; whence
when any person is weakened by fatigue or otherwise, a darker shade of
colour is seen beneath the eyes; which is owing to a less energetic action
of the absorbent terminations of the veins, whence the currents of
