an anaesthetic.

(130) _Median and posterior interosseous._--_Entry_, over the
external margin of the radius at the centre of the forearm;
_exit_, at the inner margin of the olecranon 1-1/2 inch below
the tip. Lowered cutaneous sensation in median distribution,
and loss of median flexion of wrist and fingers. Complete
wrist-drop. The triceps supinator longus and extensor carpi
radialis longior were perfect. Twelve days later the wrist
could be raised into a direct line with forearm, but there was
no change in the median symptoms. A week after this the
anaesthetic median area became hyperaesthetic both as to skin and
on deep pressure over the muscles.

(131) _Sacral plexus. Great sciatic nerve._--Wounded at Modder
River. _Entry_, in left loin; _exit_, at lower margin of
buttock. The wound was followed immediately by complete
peroneal paralysis, both motor and sensory. Fourteen days later
hyperaesthesia developed in the area of distribution of the
internal popliteal nerve, the superficial pain being greatest
in the sole; the muscles of the calf were also very tender on
manipulation. The pain increased, and at the end of twenty-four
days the patient's sufferings were so great that Mr. Thornton
cut down upon and exposed the nerve. It was found embedded in
firm cicatricial tissue close to the sciatic notch; this
compressed the nerve to such a degree that a waist was apparent
upon it.

The nerve was freed and resumed its normal outline. For a few
days the patient was much relieved, but the neuralgia then
returned in greater intensity than ever. Morphia was injected
hypodermically, and other hypnotics employed, but with little
effect, the patient developing the hysterical condition so
common in the subjects of severe sciatica. Some five weeks
later a sudden improvement took place, the morphia was
decreased, and the patient became sufficiently well to return
to England, but there was still deep tenderness in the calf,
and well-marked hyperaesthesia of the sole.

A year later the patient had been discharged from the Service,
but was earning his living in a shop. He walked fairly well,
but still with foot-drop, and complained of tenderness in the
sole. I am indebted to Dr. Turney for the following report on
the condition of the mus
