When admitted at Rondebosch into No. 3 General Hospital the condition was as follows: The field of vision is limited, and examination shows right homonymous hemianopsia. When any one comes into the tent the patient sees a shadow only until his bed is reached. When spoken to the patient 'thinks and thinks,' and then apologises for not answering, saying he will remember at some future time. He is absolutely unable to remember times, names, or localities, but places his hand to his head and appears to think deeply in the effort to recall them. Occasionally when you go into his tent he suddenly remembers something he has been trying to think of for some days, and will tell you. A fortnight later after an attack of influenza the patient was not so well, and vision was apparently becoming more impaired. An incision was made (Mr. J. E. Ker) so as to raise a flap the centre of the convexity of which was 2-1/2 inches behind the left external auditory meatus. A slight prominence and a fissure was discovered in the temporal bone, and over this a trephine was applied. On removal of the crown of bone the bullet was discovered with the point turned backwards (having evidently undergone a partial ricochet turn) on the upper surface of the petrous bone, just above the lateral sinus. The dura-mater was healed but thickened, and some clot upon its surface was removed. The wound healed per primam, and a rapid recovery was made. Ten days later a running water-tap was able to be detected 120 yards from the tent door. The hemianopsia however persisted. The following letter, dictated by the patient to his wife, and sent to me, gives a clear account of his condition ten months later:-- I am pleased to say my memory is better than it was some time ago, though at times I am entirely lost and really forget all that I was speaking about. I also find that I often call things and places by their wrong names. I sometimes try to read a paper or book which I have to read letter by letter, sometimes calling out the wrong letter, such as B for D &c., and by the time I have read almost halfway through, I have forgotten the commencement. My sight is about the same. There is no improvement in the right eye, and the doctor at Stoke said that the left eye was not as it ought to be and might get worse. I ofttimes go to take up a thing, but find I am not near to it, though it appears to me so. I have no pain to speak of in the head, though at times a shooting pain. I have a continual noise in the left ear as if of a locomotive blowing off steam, and a deafness in the left ear which I had not before being wounded. I am extremely indebted to my friend Mr. J. Errington Ker for the notes of the above case, so successfully treated by him.
