This aperture was then enlarged
until it allowed the passage of the bar in question, and the loss
of substance strikingly corresponded with the lesion said to have
been received by the patient. From the coronoid process of the
inferior maxilla there was removed a fragment measuring about 3/4
inch in length. This fragment, in the patient's case, might have
been fractured and subsequently reunited. The iron bar, together
with a cast of the patient's head, was placed in the Museum of
the Massachusetts Medical College.
Bigelow appends an engraving to his paper. In the illustration
the parts are as follows:--
(1) Lateral view of a prepared cranium representing the iron bar
traversing its cavity.
(2) Front view of same.
(3) Plan of the base seen from within. In these three figures the
optic foramina are seen to be intact and are occupied by small
white rods.
(4) Cast taken from the shaved head of the patient representing
the appearance of the fracture in 1850, the anterior fragment
being considerably elevated in the profile view.
(5) The iron bar with length and diameter in proportion to the
size of the other figures.
Heaton reports a case in which, by an explosion, a tamping-iron
was driven through the chin of a man into the cerebrum.
