(109) _Peroneal nerve branches._--Wounded at Colenso. _Entry_, at the anterior margin of the fibula 5 inches above the external malleolus; the track crossed the anterior aspect of the leg obliquely, to its _exit_ 1 inch above the centre of the ankle joint. Incomplete paralysis of the peronei muscles followed, combined with progressive wasting of the whole limb, which at the end of a month was marked, and then commenced to improve. (110) In a second case the wound took a similar course in the centre of the leg, crossing the line of the branches of the musculo-cutaneous nerve. Motor paralysis of the peronei followed, together with general lowering of tactile sensation in the musculo-cutaneous area. _Traumatic neurosis._--In connection with the cases just quoted, mention must be made of the fact that the functional element was often somewhat prominent. The influence of this factor was not to be neglected in case 108; again, its presence was a feature in cases 132 and 134, of injury to the sciatic nerve and of peripheral injury to the seventh nerve (p. 355). A remark has been made as to the occurrence of functional paraplegia on p. 337. Again, in the case of the organs of special sense. Case 66, of injury to the occipital lobes, showed that a mixture of organic and functional phenomena might be a source of error, even in the determination of the visual field in the subject of an undoubted destructive lesion. On more than one occasion an injury was accompanied by loss of the power of speech; thus a patient who received a slight wound of the neck did not speak again until the application of a battery by my colleague, Mr. H. B. Robinson. A patient was also for a short time an inmate of No. 1 General Hospital, Wynberg, who had become deaf and dumb as a result of the explosion of a shrapnel shell over his head. This patient also did not recover his powers until he returned to the mother-country. In many other cases of nerve concussion or contusion, the recovery of power and sensation, or the disappearance of neuralgia or contractures, was so sudden and rapid after prolonged continuance of the symptoms, as to suggest a very strong functional element in their origin. The influence of the general shock to the nervous system received by the patients had an important bearing on these phenomena, and their interest from a prognostic point of view was very great. INJURIES TO SPECIAL NERVES _Cranial nerves._--It will be convenient first to make a few remarks concerning the nerves of special sense.
