Dr. GREGORY. I think you will have an opportunity to see the real thing a little later if the Governor makes his appearance here. But the wound of entry I considered to be, although on his right hand, of course, to be approximately at this point on the wrist, and the wound of exit here, which is about the right level for my coat sleeve held at a casual position. Mr. SPECTER. Let the record show you made two red marks on your wrist, which are in the same position as that which you have described heretofore in technical language. Dr. GREGORY. Yes. Mr. SPECTER. Had you finished the complete explanation on the indicator from the air levels which you had mentioned before? Dr. GREGORY. Yes. The air is a little bit more visible to the dorsal surface, closer to the skin here, not so close down at the lower portion, not so much tissue destruction had occurred at the point of the emergence. Mr. SPECTER. Before proceeding to the other factors indicating point of entry and point of exit, Dr. Gregory, I call your attention to Commission Exhibit No. 399, which is a bullet and ask you first if you have had an opportunity to examine that earlier today? Dr. GREGORY. I have. Mr. SPECTER. What opinion, if any, do you have as to whether that bullet could have produced the wound on the Governor's right wrist and remained as intact as it is at the present time? Dr. GREGORY. In examining this bullet, I find a small flake has been either knocked off or removed from the rounded end of the missile. (At this point Representative Boggs entered the room.) I was told that this was removed for the purpose of analysis. The only other deformity which I find is at the base of the missile at the point where it joined the cartridge carrying the powder, I presume, and this is somewhat flattened and deflected, distorted. There is some irregularity of the darker metal within which I presume to represent lead. The only way that this missile could have produced this wound in my view, was to have entered the wrist backward. Now, this is not inconsistent with one of the characteristics known for missiles which is to tumble. All missiles in flight have two motions normally, a linear motion from the muzzle of the gun to the target, a second motion which is a spinning motion having to do with maintaining the integrity of the initial linear direction, but if they strike an object they may be caused to turn in their path and tumble end over, and if they do, they tend to produce a greater amount of destruction within the strike time or the target, and they could possibly, if tumbling in air upon emergence, tumble into another target backward. That is the only possible explanation I could offer to correlate this missile with this particular wound. Mr. SPECTER. Is there sufficient metallic substance missing from the back or rear end of that bullet to account for the metallic substance which you have described in the Governor's wrist?
