Dr. Olivier. Yes; I did.
Mr. Specter. Why was goat substance selected for that purpose in the testing procedure?
Dr. Olivier. We usually use this in our work so we are familiar with it. I am not saying it is the only substance that could be used, but we were not using any unknown procedures or any procedures that we hadn't used already.
Mr. Specter. Does it closely simulate the nature of a wound in the human body?
Dr. Olivier. In this particular instance it did.
Mr. Specter. Was the wound inflicted on the goat, then, subjected to X-ray analysis for the purpose of determining the precise nature of the wound and for comparison purposes with that wound——
Dr. Olivier. Yes; it was.
Mr. Specter. Inflicted on Connally?
Dr. Olivier. Yes; it was.
Mr. Specter. I now hand you an X-ray marked Commission Exhibit 851 and ask you to state what that shows?
