Mr. SPECTER. Or, it might be consistent with an entry wound under a different set of factors? Dr. PERRY. That's correct, sir. I, myself, have no knowledge of that. I do not think that it is consistent, for example, with an exit wound of a large expanded bullet--voluntarily I would add that. Mr. SPECTER. Well, would a jacketed 6.5-mm. bullet fit the description of a large expanded bullet? Dr. PERRY. No, sir; it would not. Mr. SPECTER. Based on the information in the autopsy report about a 6- by 15-mm. hole in the lower part of the President's skull on the right side in conjunction with the large part of the skull of the President which you observed to be missing, would you have an opinion as to the source of the missile which inflicted those wounds? Dr. PERRY. Since I did not see the initial wound which you mentioned, the smaller one, and only saw the large avulsive wound of the head and the scalp, there is no way for me to determine from whence it came. Mr. SPECTER. Well, if you assume the presence of the first small wound, taking as a fact that there was such a wound, now, would that present sufficient information for you to formulate an opinion as to source or trajectory? Dr. PERRY. Well, I couldn't testify as to exact source, but if the wound, the smaller wound that you noted were present, it could certainly result in the large avulsive wound as it exited from the skull. As to the ultimate source, there would still be no way for me to tell. Mr. SPECTER. Well, could you tell sufficient to comment on whether it came from the front or back of the President? Dr. PERRY. In the absence of other wounds of the head, the presence of the small wound which you described, in addition to the large avulsive wound of the skull and the scalp which I observed would certainly indicate that the two were related and would indicate both an entrance and an exit wound, if there were no other wounds. Mr. SPECTER. And which would be the wound of entrance, then? Dr. PERRY. The smaller wound--the smaller wound. Mr. SPECTER. Now, did you have occasion to talk via the telephone with Dr. James J. Humes of the Bethesda Naval Hospital? Dr. PERRY. I did. Mr. SPECTER. And will you relate the circumstances of the calls indicating first the time when they occurred. Dr. PERRY. Dr. Humes called me twice on Friday afternoon, separated by about 30-minute intervals, as I recall. The first one, I, somehow think I recall the first one must have been around 1500 hours, but I'm not real sure about that; I'm not positive of that at all, actually. Mr. SPECTER. Could it have been Saturday morning? Dr. PERRY. Saturday morning--was it? It's possible. I remember talking with him twice. I was thinking it was shortly thereafter. Mr. SPECTER. Well, the record will show. Dr. PERRY. Oh, sure, it was Saturday morning--yes. Mr. SPECTER. What made you change your view of that? Dr. PERRY. You mean Friday?
