It is the kind of weighing that requires a microadjustable scale, which means that it is something less than the weight of a postage stamp.
Mr. Specter. Have you now described all the metallic substances which you observed either visually or through the X-rays in the Governor's wrist?
Dr. Gregory. These are the three metallic substance items which I saw.
Now if I may use these to indicate why I view the path as being from dorsal to volar, from the back of the wrist to the palm side, these have been shed on the volar side suggesting that contact with this bone resulted in there being flaked off, as the remainder of the missile emerged from the volar side leaving the small flakes behind.
Mr. Specter. Are the X-rays helpful in any other way in ascertaining the point of entry and the point of exit?
Dr. Gregory. There is a suggestion to be seen in Exhibit B, the lateral view, a suggestion of the pathway as seen by distortion of soft tissues. This has become a bit irregular on the dorsal side. There is evidence of air in the tissues on this side suggesting that the pathway was something like this.
Mr. Specter. And when you say indications of air on which side did you mean by "this side," Doctor?
Dr. Gregory. Air distally on the volar side. There is some evidence of air in the tissue on the volar side too but they are at different levels and this suggests that they gained access to the tissue plans in this fashion.
Mr. Specter. Would you elaborate on just what do you mean by "this fashion," indicating the distinctions on the level of the air which suggest that conclusion to you?
Dr. Gregory. Recall that I suggested that the wound of entrance, certainly the dorsal wound lay some distance, 5 cm. above the wrist joint, approximately here, that the second wound considered to be the wound of exit was only 2 cm. above this point, making the pathway an oblique one.
