left orbit, the whole mass
weighing 186 Belgian grains. They were blown in by a gust of wind that
broke a pane of glass; after extraction no affection of the brain or
eye occurred. Watson speaks of a case in which a chip of steel 3/8 inch
long was imbedded in cellular tissue of the orbit for four days, and
was removed without injury to the eye. Wordsworth reports a case in
which a foreign body was deeply imbedded in the orbit for six weeks,
and was removed with subsequent recovery. Chisholm has seen a case in
which for five weeks a fly was imbedded in the culdesac between the
lower lid and the eyeball.

Foreign bodies are sometimes contained in the eyeball for many years.
There is an instance on record in which a wooden splinter, five mm.
long and two mm. broad, remained in the eye forty-seven years. It was
extracted, with the lens in which it was lodged, to relieve pain and
other distressing symptoms. Snell reports a case in which a piece of
steel was imbedded and encapsulated in the ciliary process twenty-nine
years without producing sympathetic irritation of its fellow, but
causing such pain as to warrant enucleation of this eye. Gunning speaks
of a piece of thorn 5/8 inch long, imbedded in the left eyeball of an
old man for six years, causing total loss of vision; he adds that,
after its removal, some improvement was noticed.

Williams mentions a stone-cutter whose left eye was put out by a piece
of stone. Shortly after this his right eye was wounded by a knife,
causing traumatic cataract, which was extracted by Sir William Wilde,
giving the man good sight for twelve years, after which iritis attacked
the right eye and produced a false membrane over the pupil so that the
man could not work. It was in this condition that he consulted
Williams, fourteen years after the loss of the left eye. The eye was
atrophied, and on examination a piece of stone was seen projecting from
it directly between the lids. The visible portion was 1/4 inch long,
and the end in the shrunken eye was evidently longer than the end
protruding. The sclera was incised, and, after fourteen years' duration
in the eye, the stone was removed.

Taylor reports the removal of a piece of bone which had remained
quiescent in the eye for fourteen years; after the removal of the eye
the bone was found adherent to the inner tunics. It resembled the lens
in size and shape. Williams mentions continual tolerance of foreign
bodies in the eyeball for fifteen
