Mr. Eisenberg. Mr. Frazier, could you discuss this photograph with us?
Mr. Frazier. In Commission Exhibit 568 is again the vertical dividing line through the center of the photograph, with the test bullet from the rifle 139 on the left, and the bullet, Exhibit 567, on the right. Am I right in that the bullet jacket fragment is 567?
Mr. Eisenberg. I think I put it down here. That is right, 567.
Mr. Frazier. Approximately two-thirds of a groove impression from each of the two bullets is shown, with a very small portion at the bottom of the photograph of a land impression. The individual microscopic characteristics which were used in the comparison, and on which the identification was made, were photographed and are as shown in this photograph. However, this photograph did not enter into the actual conclusion reached. The microscopic characteristics appear as parallel horizontal lines extending from the test bullet on the left to the bullet Exhibit 567 on the right.
The marks used in the identification are grooves, paired lines, a series of ridges up and down the hairline on one bullet, and they also appear on the opposite side of the photograph.
In one particular instance it will be seen that at the edge of the land impression at the lower left portion of the photograph is a very definite paired ridge which appears on the right side of the photograph but in a slightly different area.
The reason for the difference in the location of this paired line on the exhibit, Exhibit 567, can be explained by the fact that this is a jacket fragment, that it was torn from the rest of the bullet, and is greatly mutilated, distorted, and bears only a very few areas suitable for identification purposes because of that fact.
The distortion has foreshortened the area of the jacket fragment, 567, to the extent that over this approximately one-tenth-of-an-inch surface represented in this photograph, these lines do not coincide exactly on the lower part of the photograph when they are lined up on the upper part of the photograph.
Mr. Eisenberg. When you say they don't correspond exactly, do you mean at all, or do you mean they aren't——
Mr. Frazier. I mean that the marks are present, but they do not line up at the hairline.
