case in
which some modification of the sense of taste accompanied an injury to
the floor of the mouth. It was a matter of surprise, considering the
frequency with which subsequent neuritis was met with in the nerves
generally, that trifacial neuralgia in some form was not more often met
with. I never observed any serious case. Perhaps this is one of the
fields in which a longer after-period may increase our knowledge.
Lastly, I never observed motor paralysis in the case of the third
division, although sensory symptoms in some of the branches were common,
evident proof that injuries to the trunk were rare.

_Seventh nerve._--Facial paralysis was most commonly observed in cases
of wound of the mastoid process, apart from central cortical facial
paralyses, of which several are quoted in the chapter on injuries of the
head. All the wounds of the mastoid process were, in addition,
accompanied by absolute deafness. I am sorry to be unable to give any
details as to the electrical condition of the muscles in these cases,
but I believe that in the great majority the paralysis was mainly the
result of nerve concussion, since the perforations were clean in
character and not obviously accompanied by comminution. Pressure from
haemorrhage into the Fallopian canal may, of course, have been present,
and in some instances, particularly those in which the bullet traversed
the tympanic cavity, spicules of bone may have caused laceration. In
every case, however, all the branches were equally affected; the
paralysis was absolute, and in none did any improvement occur while the
cases were under my observation.

The following are a few illustrative examples:--

(111) Boer wounded at Belmont. _Entry_, immediately above
zygoma; the bullet passed through the temporal fossa, fractured
the neck of the mandible, traversed the mastoid process, and
emerged at the lower margin of the hairy scalp, 1 inch from the
median line. Facial paralysis was complete, and there was no
improvement at the end of ten weeks.

(112) Wounded at Magersfontein. _Entry_, at the posterior
border of the left mastoid process, 1/2 an inch above the tip;
_exit_, through the right upper lip at the junction of the
middle and outer thirds. There was considerable haemorrhage from
the left ear. The injury was followed by complete deafness, and
facial paralysis, which showed no sign of improvement.

There was com
