s of stimuli in the
right upper eyelid, forehead, and anterior part of the scalp,
corresponding with the distribution of the supraorbital and nasal
nerves. The cornea was completely anesthetic, and the right cheek, an
inch and a half external to the angle of the nose, presented a small
patch of anesthesia. There was undue emotional mobility, the patient
laughing or crying on slight provocation. The condition of
mind-blindness remained. It is believed that the spout of the oil-can
must have passed under the zygoma to the base of the skull, perforating
the great wing of the spheroid bone and penetrating the centrum ovale,
injuring the anterior fibers of the motor tract in the internal capsule
near the genu."
Figures 192 and 193 show the outline and probable course of the spout.
Beaumont reports the history of an injury in a man of forty-five, who,
standing but 12 yards away, was struck in the orbit by a rocket, which
penetrated through the spheroidal fissure into the middle and posterior
lobes of the left hemisphere. He did not fall at the time he was
struck, and fifteen minutes after the stick was removed he arose
without help and walked away. Apparently no extensive cerebral lesion
had been caused, and the man suffered no subsequent cerebral symptoms
except, three years afterward, impairment of memory.
There is an account given by Chelius of an extraordinary wound caused
by a ramrod. The rod was accidentally discharged while being employed
in loading, and struck a person a few paces away. It entered the head
near the root of the zygomatic arch, about a finger's breadth from the
outer corner of the right eye, passed through the head, emerging at the
posterior superior angle of the parietal bone, a finger's breadth from
the sagittal suture, and about the same distance above the superior
angle of the occipital bone. The wounded man attempted to pull the
ramrod out, but all his efforts were ineffectual. After the tolerance
of this foreign body for some time, one of his companions managed to
extract it, and when it was brought out it was as straight as the day
it left the maker's shop. Little blood was lost, and the wound healed
rapidly and completely; in spite of this major injury the patient
recovered.
Carpenter reports the curious case of an insane man who deliberately
bored holes through his skull, and at different times, at a point above
the ear, he inserted into his brain five pieces of No. 20 broom wire
