Mr. SPECTER. Have you now told me about all of the talks you have had with representatives of the Federal Government prior to today? Dr. PERRY. I think I have. Mr. SPECTER. And did you and I sit down and talk about the purpose of this deposition and the questions which I would be asking you on the record, before this deposition started? Dr. PERRY. Yes; we did. Mr. SPECTER. And did you give me the same information which you provided on the record here today? Dr. PERRY. I have. Mr. SPECTER. Do you have anything to add which you think might be helpful in any way to the President's Commission? Dr. PERRY. No, sir. Mr. SPECTER. Dr. Perry, we appreciate your coming for your deposition today, and I have given you a letter requesting your presence in Washington on Monday morning at 9 o'clock and I would ask you, for the record, to acknowledge receipt of letter, if you will, please. Dr. PERRY. Yes; I have the letter here and I will be there. Mr. SPECTER. Thank you, very much, sir. Let me ask you one more question, Dr. Perry, for the record, before we terminate this deposition. What experience have you had, if any, with gunshot wounds? Dr. PERRY. I think in the course of my training here at Parkland, which is a city-county hospital and handles the great majority of the trauma cases that occur in Dallas County, that I have seen a fairly considerable number of traumatic wounds caused by knives, automobile accidents, gunshot wounds of various types. Mr. SPECTER. Have you had any experience with gunshot wounds, in addition to that obtained here at Parkland? Dr. PERRY. You mean, in the service? Mr. SPECTER. Yes, sir. Dr. PERRY. No, I had occasion to see only one gunshot wound while I was in the service. Mr. SPECTER. Can you estimate how many gunshot wounds you have seen while you have been at Parkland? Dr. PERRY. Probably it would be numbered in the hundreds. Mr. SPECTER. Have you had any formal training in ballistics? Dr. PERRY. No, other than the fact that I do some hunting and amateur hand loader. Mr. SPECTER. Amateur what? Dr. PERRY. Amateur hand loader--hand load ammunition. Mr. SPECTER. Thank you very much. Dr. PERRY. All right. Thank you. TESTIMONY OF DR.
