ight angles just within the margin of
the hairy scalp. The regiment was at the time to all intents
and purposes outside the range of rifle fire, and the patient
was the only individual struck among its number. When brought
into the Highland Brigade Field Hospital, a single typical
entry wound was discovered; examination with the probe gave
evidence of a slight depression in the external table of the
frontal bone just above the temporal ridge. Although no
perforation was detectible by the probe, and this was
positively excluded on the raising of a flap (Major Murray,
R.A.M.C.), it was considered advisable to remove a 1/4-inch
trephine crown, the pin of the instrument being applied to the
margin of the depression. No depression or splintering of the
internal table was discovered, nor any injury to the dura, nor
blood upon the surface of that membrane. The man made an
uninterrupted recovery.

(46) A case of frontal injury was shown to me at Wynberg, in
which a distinct furrow could be traced across the upper part
of the frontal sinuses. There had been no symptoms beyond
temporary diplopia, and the wound was healed; no surgical
interference had been deemed necessary.

(47) In a man wounded at Poplar Grove, a single typical wound
of entry was found 3/4 of an inch above the right eyebrow and
the same distance from the median line. No primary symptoms
were observed, but on the evening of the second day the
temperature rose above 100 deg. F., and the man seemed somewhat
heavy and dull. The patient was examined by Major Fiaschi and
Mr. Watson Cheyne, and it was decided to explore the wound. Mr.
Cheyne removed fragments both of external and internal tables,
one of the latter having made a punctiform opening, not
admitting the finest probe, in the dura-mater. The bullet was
traced into the nasal fossae, where it was subsequently
localised with the aid of the Roentgen rays when the patient
came under my observation at Wynberg some days later (fig. 60).

_Gunshot fracture of the skull with concurrent brain injury._--This was
the commonest form of head injury, and possessed two main peculiarities;
firstly, the large amount of brain destruction compared with the extent
of the bone lesion; secondly, the fact that any region of the skull was
equally open to damage. In co
