Mr. Eisenberg. Those are the test bullets fired by the FBI.

Mr. Dulles. I was a little puzzled by the order.

Mr. Eisenberg. Yes. That is just the order in which they were introduced in evidence.

Mr. Dulles. And really 573 came before 572 in terms of time.

Mr. Eisenberg. Yes.

Mr. Dulles. That clears it up for me.

Mr. Nicol. This is the condition of the bullet.

Mr. Dulles. I have seen the bullet, yes.

Mr. Nicol. It is in sad shape, to say the least.

Mr. Eisenberg. As I understand your testimony, therefore, you feel that there are sufficient identical microscopic characteristics on 572 and 573 to say that they were probably fired from the same weapon, but not enough to say that they were definitely fired from the same weapon.
