Mr. SPECTER. Would you describe that as being a straight line? Dr. OLIVIER. Yes. Mr. SPECTER. I now hand you a picture marked Commission Exhibit No. 850 and ask you what that represents? Dr. OLIVIER. These are pieces of clipped goatskin, clipped very shortly. There is still some hair on it. These were placed, these particular ones were placed over the tissues. This would be placed over the entrance side of the animal. Mr. SPECTER. When you say "this," you are referring to a piece of goatskin which is marked "enter"? Dr. OLIVIER. Marked "enter." The one marked "exit" was placed on the far side of the tissues and the bullet passed through that after it came out of the tissues. Mr. SPECTER. For the record, will you describe the characteristics, which are shown on the goatskin at the point of entry, please? Dr. OLIVIER. At the point of entry the wound holes through the skin are for all purposes round. On the exit side they are more elongated, two of them in particular are a little more elongated. The bullet had started to become slightly unstable coming out. Mr. SPECTER. And how about the third or lower bullet on the skin designated exit? Dr. OLIVIER. That hole appears as more stable than the other two. In all three cases the bullet is still pretty stable. The gelatin blocks, there were gelatin blocks placed behind these things too, and for all practical purposes, the tracks through them still indicated a stable bullet. Mr. SPECTER. Are there any other conclusions which you would care to add to those which you have already indicated, resulting from the tests you have heretofore described? Dr. OLIVIER. Well, it means that the bullet that passed through the President's neck had lost very little of its wounding potential and was capable of doing a great deal of damage in penetrating. I might mention one thing showing how great its penetrating ability was. That say on one of the gelatin shots, it went through a total, counting the gelatin block, it went through plus the backing up blocks of gelatin, it went through a total of 72-1/2 centimeters of gelatin, was still traveling and buried itself in a mound of earth so it has terrific penetrating ability. This means that had the bullet that passed through the President's neck hit in the car or anywhere you would have seen evidence, a good deal of evidence. Mr. SPECTER. Dr. Olivier, in the regular course of your work for the U.S. Army, do you have occasion to perform tests on animal materials where the characteristics of those animals materials are sufficiently similar to human bodies to make a determination of the effect of the bullet wounds in human bodies? Dr. OLIVIER. Yes; I do. Mr. SPECTER. And did you have occasion to make a test on goat material in connection with the experiments which you ran? Dr. OLIVIER. Yes. Mr. SPECTER. Are you familiar with the wounds inflicted on Governor Connally on November 22, 1963?
