Mr. Dulles.

Senator COOPER. I think, of course, it is evident from your testimony you have had wide experience in chest wounds and bullet wounds in the chest.
What experience have you had in, say, the field of ballistics? Would this experience you have been dealing in chest wounds caused by bullets--have provided you knowledge also about the characteristics of missiles, particularly bullets of this type?
Dr. SHAW. No; Senator. I believe that my information about ballistics is just that of an average layman, no more. Perhaps a little more since I have seen deformed bullets from wounds, but I haven't gone into that aspect of wounds.
Senator COOPER. In the answers to the hypothetical questions that were addressed to you, based upon the only actual knowledge which you could base that answer, was the fact that you had performed the operation on the wound caused in the chest, on the wound in the chest?
Dr. SHAW. That is true. I have seen many bullets that have passed through bodies or have penetrated bodies and have struck bone and I know manners from which they are deformed but I know very little about the caliber of bullets, the velocity of bullets, many things that other people have much more knowledge of than I have.
Senator COOPER. That is all.

The Chairman.

Thank you very much, Dr. Shaw.

Dr. Charles Francis Gregory

Testimony of Dr. Charles Francis Gregory

Senator COOPER. Do you solemnly swear the testimony you are going to give to this Commission will be the truth, the whole truth, and nothing but the truth, so help you God?
Dr. GREGORY. I do.

Mr. Specter.

Would you state your full name for the record, please?
Dr. GREGORY. Doctor Charles Francis Gregory.

Mr. Specter.

What is your profession, sir?
Dr. GREGORY. I am a physician and surgeon.

Mr. Specter.

Would you outline your educational background briefly, please?
Dr. GREGORY. I received a bachelor of science degree from the University of Indiana in 1941, and an M.D. degree in medicine from the Indiana University School of Medicine in 1944.
Following 1-year internship and a tour of duty in the U.S. Navy, I undertook 5 years of postgraduate training in orthopedic surgery at Indiana University Medical Center.
Upon completing that training I became a member of the faculty at Indiana University Medical School, and remained so until November of 1952, when I re-entered the U.S. Navy for another 20 months.
In 1956 I was appointed professor and then chairman of the Division of Orthopedic Surgery at the University of Texas Southwestern Medical School, where I presently am.

Mr. Specter.

Are you certificated by the American Board of Orthopedic Surgery?
Dr. GREGORY. I am, in 1953.

Mr. Specter.

What experience, if any, have you had with bullet wounds, Doctor?
Dr. GREGORY. Beyond the rather indigenous nature of such wounds in the main teaching hospital at Southwestern Medical School, my experience has covered a tour of duty in the, Navy during World War II, and a considerably more active period of time in the Korean war in support of the 1st Marine Corps Division.

Mr. Specter.

What is your best estimate as to the total number of bullet wounds you have had an opportunity to observe and treat?
Dr. GREGORY. I would estimate that I have dealt directly with approximately 500 such wounds.

Mr. Specter.

Are you a licensed doctor in the State of Texas at the present time?
Dr. GREGORY. I am.
