of the canal.
Projecting from the meatus there was enough of this prong to be easily
grasped between one's thumb and finger. Removal of the hair-pin was
effected by first inserting within the meatus a Gruber speculum,
encircling the unbroken projecting prong, and then raising the end of
the broken one with a long-shanked aural hook, when the hair-pin was
readily withdrawn. The wound of the canal-floor promptly healed.

In the severest forms of scalp-injuries, such as avulsion of the scalp
from the entangling of the hair in machinery, skin-grafting or
replantation is of particular value. Ashhurst reports a case which he
considers the severest case of scalp-wound that he had ever seen,
followed by recovery. The patient was a girl of fifteen, an operative
in a cotton-mill, who was caught by her hair between two rollers which
were revolving in opposite directions; her scalp being thus, as it
were, squeezed off from her head, forming a large horseshoe flap. The
linear extent of the wound was 14 inches, the distance between the two
extremities being but four inches. This large flap was thrown backward,
like the lid of a box, the skull being denuded of its pericranium for
the space of 2 1/2 by one inch in extent. The anterior temporal artery
was divided and bled profusely, and when admitted to the hospital the
patient was extremely depressed by shock and hemorrhage. A ligature was
applied to the bleeding vessel, and after it had been gently but
carefully cleansed the flap was replaced and held in place with gauze
and collodion dressing. A large compress soaked in warm olive oil was
then placed over the scalp, covered with oiled silk and with a
recurrent bandage. A considerable portion of the wound healed by
adhesions, and the patient was discharged, cured, in fifty-four days.
No exfoliation of bone occurred. Reverdin, a relative of the discoverer
of transplantation of skin, reported the case of a girl of twenty-one
whose entire scalp was detached by her hair being caught in machinery,
leaving a wound measuring 35 cm. from the root of the nose to the nape
of the neck, 28 cm. from one ear to the other, and 57 cm. in
circumference. Grafts from the rabbit and dog failed, and the skin from
the amputated stump of a boy was employed, and the patient was able to
leave the hospital in seven months. Cowley speaks of a girl of fourteen
whose hair was caught in the revolving shaft of a steam-engine, which
resulted in the tearing off of he
