ked down by a horse, and that
his acquaintances accuse him of passing them unnoticed. The
fields of vision are very small, but the loss is not typically
in the temporal half of either. That of the right eye which we
know as the spiral field, becoming more and more contracted as
the perimeter test is continued, is what is found in functional
cases; that of the left, however, shows a characteristic loss
of the lower part of the field of vision, and agrees with the
statement of the man that he can see the upper part of my face
but not the lower when he looks at me. Such a loss agrees with
a lesion involving the upper part of the cuneate lobe above the
calcarine fissure.

I feel satisfied that there is considerable loss in the right
field also, but the functional element obscures its exact
nature.

The fundi, pupils, and ocular movements are all normal.

(67) _Injury to occipital lobes and left motor and sensory
areas._--Wounded outside Lindley (Spitzkop). Range within 1,000
yards. _Entry_, one inch within the right lateral angle of the
occipital bone, external wound more than 1/2 an inch in
diameter; _exit_, 2 inches from the median line, over the upper
half of the left fissure of Rolando. Behind the wound of exit
comminution of the parietal bone, extending back to the
lambdoid suture, existed. I attributed this to oblique lateral
impact by the bullet on the inner surface of the skull.

The patient could afterwards remember being struck, but became
rapidly unconscious. When brought into the Field hospital some
five hours later the condition was as follows: Semi-conscious,
can speak, apparently blind, pupils equal, of moderate size, do
not react to light. Right hemiplegia. No sickness. Moans with
pain in head. Passes water normally.

Considerable haemorrhage had occurred from each wound, the scalp
was puffy, and the bones yielded on pressure over the left
parietal bone, indicating considerable comminution.

The night was so cold that no operation could be considered, so
the head was partly shaved, the wounds cleansed, and a dressing
applied. The next morning the Division marched at 5 A.M., and
it was considered wise to leave the man at Lindley in the local
hospital.
