Dr. JONES. As I recall, there had been in news that the President had several years ago been on some type of steroid therapy and that he possibly had Addison's disease. We had no documented evidence that he did or did not, but caution was taken nonetheless in case his insufficiency was of severe enough nature, because at the time of severe trauma a patient with adrenal insufficiency often goes into a rapid degree of adrenal insufficiency and can expire from lack of steroids being produced from the adrenal gland in such a stressed situation. Mr. SPECTER. Did you obtain that history from Mrs. Kennedy, or any other person on the scene? Dr. JONES. No. Mr. SPECTER. You just relied upon what had been occurring in the news? Dr. JONES. Yes. Mr. SPECTER. What would that reaction cause, if anything, if the President had no adrenal insufficiency? Dr. JONES. This would not cause severe effects on any organ at all if the adrenal gland were producing enough steroids. Mr. SPECTER. Did any other doctors arrive during the time this treatment was going on, other than those whom you have already mentioned? Dr. JONES. Several doctors did subsequently appear in the room--Dr. McClelland appeared shortly after Dr. Baxter, within a matter of just a very few minutes, as well as Dr. Kemp Clark, who is head of neurosurgery here. Mr. SPECTER. Any other doctors? Dr. JONES. Dr. Jenkins was there and I think these are primarily the ones that actually had any part, as far as taking care of the President, although there were some other doctors in the room. Mr. SPECTER. Dr. Jones, I now hand you a report which purports to bear your signature, labeled "Summary of treatment of the President," dated November 23, 1963, which I shall now ask the Court Reporter to mark as Dr. Jones' Exhibit No. 1. (Instrument mentioned marked by the Reporter as Dr. Jones' Exhibit No. 1, for identification.) Mr. SPECTER. I ask you if this in fact is your signature? Dr. JONES. Yes. Mr. SPECTER. And I ask you if this was the report which you submitted concerning your participation of the treatment of President Kennedy? Dr. JONES. Yes; it was. Mr. SPECTER. In this report, Dr. Jones, you state the following, "Previously described severe skull and brain injury was noted as well as a small hole in anterior midline of the neck thought to be a bullet entrance wound." What led you to the thought that it was a bullet entrance wound, sir? Dr. JONES. The hole was very small and relatively clean cut, as you would see in a bullet that is entering rather than exiting from a patient. If this were an exit wound, you would think that it exited at a very low velocity to produce no more damage than this had done, and if this were a missile of high velocity, you would expect more of an explosive type of exit wound, with more tissue destruction than this appeared to have on superficial examination. Mr. SPECTER. Would it be consistent, then, with an exit wound, but of low velocity, as you put it?
