Do you want to introduce the third at this time?
Mr. Eisenberg. Yes.
This is a photograph taken by you?
Mr. Nicol. Yes, sir.
Mr. Eisenberg. Of the same cartridge case?
Mr. Nicol. Same cartridge case in a different position, rotated in a different position.
Mr. Eisenberg. May I have permission to introduce this as 624, Mr. Chairman?
Mr. Dulles. It may be admitted.
(The photograph described was marked Commission Exhibit No. 624 and was received in evidence.)
Mr. Nicol. If we compare 624 and 621 in the same general fashion, again we we have a match of the individual characteristics. So that again the same mechanical operation occurred on this cartridge case, 543, three different times, and in a rather random fashion. They are not the angular relationship between each of these sets of patterns—it is not divisible by any particular number. It is just a random occurrence.
