f the left orbit, cutting the optic nerve and
injuring the back of the eyeball, floor of the orbit, the
antrum, the hard palate, and tongue. _Exit_, in mid line of the
submaxillary region. No cerebral symptoms were noted, and on
the fifth day the man was sent to the Base hospital without
operation; the pulse was then 70 and the temperature normal.
The movements of the eyeball were perfect, but blindness was
absolute. At the Base hospital the eye suppurated and was
removed. The patient was then sent home apparently well. He has
since been discharged from the service, and is now employed as
a painter in Portsmouth Dockyard.

(50) _Vertical perforation of frontal bone._--Wounded at
Paardeberg while in the prone position. Range, 600-700 yards.
Aperture of _entry_ (Mauser), at the fore margin of the hairy
scalp above the centre of the right eyebrow; course, through
the anterior third of the right frontal lobe, roof of orbit,
front of eyeball, margin of floor of orbit making a distinct
palpable notch, and cheek; _exit_ through the red margin of the
upper lip, 1/2 an inch from the right angle of mouth. The
bullet slightly grooved the lower lip.

The patient rose almost immediately after being struck, and
walked about a mile, although feeling dizzy and tired. The
wounds, which both bled considerably, were then dressed. After
three days' stay in a Field hospital, the patient was sent in a
bullock wagon three days and nights' journey to Modder River
and thence to the Base.

There was anaesthesia over the area supplied by the outer branch
of the supra-orbital nerve, extending from the supra-orbital
notch backwards into the parietal region, but none over the
area supplied by the second division of the fifth nerve.

On the tenth day there were no signs of cerebral disturbance
except a pulse of 48. The eyeball was suppurating, and the
temperature rose to 99 deg. at night. The lids were still swollen
and closed.

A few days later the eyeball was removed and at the same time a
flap was raised and the fracture explored (Major Burton,
R.A.M.C.). An opening somewhat angular, 1/3 of an inch in
diameter, was found with a thin margin in the outer table of
the skull (fig. 62); when this was enlarged with a Hoffman's
forceps, an opening in the d
