Mr. Frazier. Yes, sir.
Mr. Eisenberg. Mr. Chairman, may I have this admitted?
Mr. McCloy. It may be admitted.
Mr. Eisenberg. 570.
(The item was identified as Commission Exhibit No. 570 and was received in evidence.)
Mr. Eisenberg. Can you discuss this picture?
Mr. Frazier. Commission Exhibit 570 shows a portion of the test bullet from Exhibit 139 on the left side of the photograph, and a portion of the bullet 569 on the right side, divided by a hairline.
The photograph was taken of the microscopic marks, examined through the comparison microscope, consisting of very fine and very coarse grooves, or scratches, or ridges, on the surface of each of the bullets as compared with those on the other bullet.
The photograph did not, of course, enter into the conclusion reached in the examination, but was merely taken to demonstrate, to illustrate the types of marks present insofar as a photograph can show them.
Mr. Eisenberg. Mr. Frazier, what portion of the Exhibit 569 was unmutilated enough to allow you to make a comparison of its markings?
