How much damage he would have had to his motor system, that is, the ability to control or coordinate his left extremities, I would not know. This conceivably could have been a problem in enabling him to move about, to appear in public, et cetera. Finally, and probably most important, since the brain, as far as at its higher levels, largely as a unit, the loss of this much brain tissue likely would have impaired his ability in abstract reasoning, imagination; whereas, the part of the President's brain struck is not that part specifically concerned with these matters. The effect of loss of considerable brain tissue does affect the total performance of the organ in these matters. There would be grave doubts in my mind as to our ability as physicians to give a clear answer regarding his ability to function as President of the United States. Our ability to judge this is sometimes sorely tried when dealing with people with considerably less intellectual and moral demands made upon them. Mr. SPECTER. Doctor, did you prepare certain written reports based on your participation in the treatment of President Kennedy? Dr. CLARK. Yes, sir; I did. Mr. SPECTER. And I now show you a document which has been supplied to the President's Commission, which we have marked as Commission Exhibit No. 392, and I now show you the second and third sheets, which purport to be the summary made by you and ask if that was prepared by you? Dr. CLARK. Yes, sir; it was. Mr. SPECTER. And, are the facts set forth in those two sheets true and correct? Dr. CLARK. Yes, sir. Mr. SPECTER. And I now show you a 2-3/4-page summary which purports to bear your signature, being dated November 22, 1963, and I ask you if that, in fact, is your signature? Dr. CLARK. Yes; it is. Mr. SPECTER. And, was, in fact, this report made in your own hand concerning the treatment which you rendered to the President? Dr. CLARK. Yes, sir. Mr. SPECTER. And are the facts set forth therein true and correct? Dr. CLARK. Yes, sir. Mr. SPECTER. Have you made any other written report or other writings of any sort concerning this matter? Dr. CLARK. No; I have not. Mr. SPECTER. Have you been interviewed or discussed this matter with any Federal representative prior to today? Dr. CLARK. Yes, sir; I have. Mr. SPECTER. And whom did you talk to? Dr. CLARK. I talked to an FBI agent a few days after the assassination, in Mr. Jack Price's office. Mr. SPECTER. And who is Mr. Price, for the record at this point? Dr. CLARK. He is the administrator of Parkland Memorial Hospital. This agent asked me if I had recovered any missiles or fragments of missiles from the President's body. I said I did not, and he asked me if I knew of anyone in Parkland Hospital who had recovered such evidence and I assured him I did not. Mr. SPECTER. Did he ask you anything further? Dr. CLARK. No, sir. Mr. SPECTER. Did you tell him anything further?
