Dr. Gregory. No, sir; I do not.
Mr. Dulles. Are you in agreement with the deposition as given?
Dr. Gregory. Yes. I don't think there are any—there is any need to change any of the essence of the deposition. There are a few typographical errors and word changes one might make, but the essence is essentially as I gave it.
Mr. Specter. I have no further questions, sir.
Senator Cooper. I would just ask this question. In your long experience of treating wounds, you said some 500 wounds caused by bullets, have you acquired, through that, knowledge of ballistics and characteristics of bullets?
Dr. Gregory. Within a very limited sphere.
Senator Cooper. I know your testimony indicates that.
Dr. Gregory. I have been concerned with the behavior of missiles in contact with tissues, but I am not very knowledgeable about the design of a missile nor how many grains of powder there are behind it. My concern was with the dissipation of the energy which it carries and the havoc that it wreaks when it goes off.
Senator Cooper. You derived that knowledge from your actual study of wounds and their treatment?
Dr. Gregory. Study of wounds together with what I have read from the Army proving grounds, various centers, for exploring this kind of thing. I don't own a gun myself.
