Mr. Eisenberg. But in your opinion the marks on the left are the same as the marks on the right?
Mr. Frazier. The marks on the left are the same marks as those on the right. In the examination this is easily determined by rotating the two bullets. As you rotate them, you can see these characteristic patterns line up.
Then you will notice these do not line up. But as you rotate one bullet, you can follow the individual marks mentally and see that the same pattern is present and you can line them up in your mind, even though they are not actually physically lined up in the microscope.
Mr. McCloy. They are not lined up in the microscope because there is mutilation on the fragment?
Mr. Eisenberg. Yes, sir.
Mr. McCloy. And there is no mutilation on the test cartridge?
Mr. Frazier. Yes, sir.
Mr. Eisenberg. Mr. Frazier, in the lower portion of each side of that photograph, which I take it is the groove of the bullet, or the land impression of the rifle—is that correct?
Mr. Frazier. The land on the rifle leaves this groove on the bullet.
Mr. Eisenberg. Yes; the right-hand side seems to be slightly striated while the left-hand side does not seem to be striated. Can you explain that?
