Subsequently the patient suffered with Jacksonian seizures, sometimes starting spontaneously, sometimes following interference with the wound. The convulsions commenced in the muscles of the face, and the twitchings then became general. Meanwhile the right upper extremity remained weak, although the fist could be clenched, and all movements of the limb made in some degree. Some difficulty was experienced in maintaining a free exit for the pus, which was however overcome by the use of a silver tube. All twitchings ceased about a month after the opening of the abscess, the man improved steadily, and he left for England fifteen weeks after the reception of the injury, walking well, with a firm hand-grip, and the wounds soundly healed. (71) _Frontal injury. Secondary abscess._--Wounded at Modder River. Aperture of _entry_ (Mauser), just external to the centre of the right eyebrow; _exit_, above the centre of the right zygoma. The wound did not render the man immediately unconscious, but he lost all recollection of what had happened to him for the next three or four days. The wounds were explored on the second day, at which time the patient was in a semi-conscious drowsy state, the pupils contracted and the pulse slow. A number of fragments of bone and pulped brain matter were removed. Subsequently to the operation the patient showed more signs of cerebral irritation than usual, lying in a semi-conscious state and more or less curled up. He answered questions on being bothered. He improved somewhat, and was sent to the Base, where the improvement continued, but he suffered much from headache. Later the headache became much more severe, and eleven weeks after the injury the man complained of great pain both locally and over the whole right hemisphere; he lay moaning, with the temperature subnormal, and the pulse very slow. At times there was nocturnal delirium. The wound had remained closed and apparently normal, but now a small fluctuating pulsating nipple-like swelling developed in the situation of the aperture of entry. This was incised, and two ounces of sweet pus evacuated (Professor Dunlop). A tube was introduced, and removed later on the cessation of discharge. Removal of the tube was followed by a recurrence of the same symptoms, and this occurred on no fewer than six occasions whenever the wound closed. At the end of twenty weeks the patient appeared quite well, the wound had been closed six weeks, the previously irritable mental state was replaced by placidity, and he was sent home.
