age (Mr. Jameson) some three weeks later.

Vision was affected at the time of the accident; the fingers
could be seen, but not counted. After ligation of the carotid
the condition was possibly worse, and this needs mention as
transitory loss of power in the left upper extremity also
followed the operation.

Fractures of the bony wall were of every degree. The most severe that I
saw were two in which lateral impact by a bullet crossing the cranial
cavity caused general comminution of the whole orbital roof. Fissures of
the roof were common in connection with 'explosive' exit apertures in
the frontal region of the skull. Pure perforations usually accompanied
the vertical or transverse wounds of the cavity, fragments at the
aperture of entry then being projected into the orbit, sometimes
penetrating the muscles.

Occasionally the margin of the cavity was merely notched.

The ocular muscles were often divided more or less completely, and
occasionally some difficulty arose in determining whether loss of
movement of the globe in any definite direction depended on injury to
the muscle itself, or to the nerve supplying the muscle. The following
case illustrates this point:--

(75) _Entry_ (Mauser), 2 inches behind the right external
canthus; the bullet pierced the external wall and traversed the
floor of the right orbit beneath the globe, crossed the nasal
cavity, and a part of the left orbit; _exit_, at the lower
margin of the left orbit, beneath the centre of the globe of
the eye.

Complete loss of sight followed the injury, and persisted for
one week. Modified vision then returned.

Three weeks later there was diplopia; loss of function of the
right external and inferior recti, although the ball could be
turned downward to some extent by the superior oblique when the
internal rectus was in action. Movements of the left globe were
not seriously affected.

The pupils were immobile and moderately dilated, but atropine
had been employed two days previously.

A year later the condition was as follows: There is some
weakness of the right seventh nerve, as evidenced by want of
symmetry in all the folds of the face, and in narrowing of the
palpebral fissure.

When at rest the right eye is somewhat raised and turned
outwards. Active movements outwards or downwards are
restricted. There i
