Mr. Specter.

his adrenal glands, since it was common medical knowledge that he suffered from adrenal insufficiency.
Of course, oxygen and pressure breathing were being effected under the guidance of Dr. Jenkins and Dr. Giesecke, who were handling the anesthesia machine at the head of the table.
Dr. Bashour and Dr. Seldin, in addition to Dr. Clark, had arrived and also assisted in monitoring cardiac actions, as indicated by the oscilloscope and the cardiotachioscope.
Mr. SPECTER. Have you now described all of the operative procedures performed on the President?
Dr. PERRY. Yes, all that I am familiar with.
Mr. SPECTER Are there any doctors who participated other than those whom you have already identified in the course of your description ?
Dr. PERRY. Yes, sir; immediately on arriving there, and as I say, Dr. Jones and I, and I saw Dr. Carrico, and I have the impression there was another physician there, but I don't know who it was. I asked that an emergency call be placed for Dr. Kemp Clark, chief of neurosurgery, for Dr. Robert McClelland, and Dr. Charles Baxter, assistant professors of surgery. They responded immediately. I don't know how long it took them to get there, but they were probably there within the next few minutes. My first recollection of Dr. McClelland and Dr. Baxter being there was when I was doing the tracheotomy, they suddenly were there assisting me. I don't know when they came in the room, nor do I know when Dr. Clark or the other gentlemen arrived, and there must have been 10 or 12 doctors all told by then.

Mr. Specter.

Are there any others whom you could identify ?

Dr. PERRY. Dr. Peters---I previously mentioned, Dr. Paul Peters, assistant professor of urology, Dr. Fouad Bashour, associate professor of medicine, and chief of cardiology, and Dr. Don Seldin, chief of medicine.
I mentioned Dr. M. T. Jenkins, chief of anesthesia, and Dr. Giesecke, his assistant professor of anesthesiology---that's the only people that I saw directly.

Mr. Specter.

Could the first doctor whom you saw have been Dr. Don Curtis?
Dr. PERRY. That's entirely possible---I don't recall.

Mr. Specter.

Was Dr. Dulany there?

Dr. PERRY. I have initially had the impression that Dr. Dulany was in the room when I came in there, but as I understand it, he actually was just going into the room across the hall, but he was there by the door when I came in, but I had the impression he was leaving that room, but I understand he was not, that actually he was going---just going in the room across the hall with the Governor, although I initially thought Dr. Dulany was there.
Mr. SPECTER. What did you observe, if anything with respect to bruising in the interior portion of the President's neck? Dr. PERRY. There was considerable hematoma in the right lateral portion of the neck and the right superior mediastinum, as I noted. As for bruising, per se, it would be difficult to describe that, since by definition, hematoma would be a collection of blood, and there was so much blood that the tissues were discolored. I did not attempt to ascertain trajectory or path of the bullet at the time, but directed myself to obtaining an adequate airway and carried, my examination no further down than it was necessary to assure myself that the trachea was controlled and that there was no large vessel injury at that level.
Mr. SPECTER. Were there sufficient facts available to you for you to reach a conclusion as to the cause of the wound on the front side of the President's neck?
Dr. PERRY. No, sir, there was not. I could not determine whether or how this was inflicted, per se, since it would require tracing the trajectory.

Mr. Specter.

What did you observe as to the President's head, specifically ?
Dr. PERRY. I saw no injuries other than the one which I noted to you, which was a large avulsive injury of the right occipitoparietal area, but I did not do a minute examination of his head.

Mr. Specter.

Did you notice a bullet hole below the large avulsed area ?
Dr. PERRY. No; I did not.

Mr. Specter.

Dr. Perry, earlier I asked you whether you tuned over the
