Mr. DULLES. I think you had better get them marked. We haven't got them marked yet "A," "B," and "C." Representative BOGGS. Postoperative, these are after the operation? Dr. GREGORY. These two. This one was made before the wound was dealt with. Mr. SPECTER. Which one? Dr. GREGORY. "A" is the one made before the wound was dealt with surgically. Senator COOPER. Could you mark it 4 "A," "B," "C," and "D," Doctor? Mr. McCLOY. Is that "B," we have had another "B" here, you know? Dr. GREGORY. This is "C." "A" and "C" are comparable X-rays, one made before and one made after the operation was carried out. Before the operation, you will note a large fragment of metal visible here, not visible in this one. You will also note a small satellite fragment not visible here. A second piece of metal visible preoperatively is still present postoperatively. No effort incidentally is made to dissect for these fragments. They are small, they are proverbial needles in hay stacks, and we know from experience that small flakes of metal of this kind do not ordinarily produce difficulty in the future, but that the extensive dissection required to find them may produce such consequences and so we choose to leave them inside unless we chance upon them, and on this occasion, those bits of metal recovered were simply found by chance in the course of removing necrotized material. Other than that the X-rays have nothing more to offer so far as the wrist is concerned. Mr. SPECTER. May we then reserve 692 for "C" and 693 for "D"? Dr. GREGORY. I will put the other marks on these. Senator COOPER. So ordered. Dr. GREGORY. For your convenience. Mr. DULLES. Was the wound of exit in the wrist also jagged like the wound of entry or was there, what differences were there between the wound of entry and the wound of exit? Dr. GREGORY. The wound of exit was disposed transversely across the wrist exactly as I have it marked here. It was in the nature of a small laceration, perhaps a centimeter and a half in length, about a half an inch long, and it lay in the skin creases so that as you examined the wrist casually it was a very innocent looking thing indeed, and it was not until it was probed that its true nature in connection with the remainder of the wound was evident. Senator RUSSELL. When did you first see this bullet, Doctor, the one you have just described in your testimony? Dr. GREGORY. This bullet? Senator RUSSELL. Yes. Dr. GREGORY. This morning, sir. Senator RUSSELL. You had never seen it until this morning? Dr. GREGORY. I had never seen it before this time. Mr. SPECTER. Dr. Gregory, what was then the relative size of the wounds on the back and front side of the wrist itself?
