 3. Several areas on the right arm just above the wrist were darkened but were not similar to the carbon black of the outer areas. These areas were reddish-black, similar to an abrasion, but the epidermis was intact. The skin was toughened in these areas suggesting coagulation of the protein material.

4. Microscopic examination of the fractures of the fingers of the right hand showed splinters of bone in random directions to the main shaft. There were several areas of split bone with osseous strands bridging the separated bone sections.

5. Microsopic examination of the right hand revealed numerous fibers adhering to the surface and imbedded in the tissue. One fiber was observed protruding from the epidermis like a growing hair. The surrounding tissue was relatively free of foreign matter. Upon pulling the single fiber a whole bundle of about 2 mm. in diameter emerged from under the skin. The epidermis then retracted leaving a pinpoint hole with an underlying pocket lined with clean subcutaneous tissue.

The foreign particles removed from the tissues of the body of Mr. Frank were mostly quite small in size but included one object 7.2 cm in diameter. The majority of these particles were examined in the laboratories of the Federal Bureau of Investigation.

Some of the more significant particles included:

1. Small metal wire .025 inch diameter, imbedded in the right wrist.

2. A small piece of brass was found in the left forearm, several pale greenish-brown threads about 10 cm. long, and also some balled-up fine fibers.

3. From the right knee, thigh, and hip over twenty separate items were removed. These included, wires, fibers, and a number of other different colored materials not identified.

4. From deep within the left leg, five small items were removed. In addition two pieces of a woman's hat ornament were found in the muscle tissue of this left leg. One was circular in shape 1.4 cm. in diameter and 1 mm. thick; the other was 7.2 cm. in diameter and 1 mm. thick. Both pieces were grey-tan in color and were of coarse velvet-like material. Attached to the longer piece was a piece of a woman's hat veil 8 by 2 cm. in size.

5. Metal particles were also found in the chest tissue, and a number of fibers were found in the tissue of the face.

Extensive search for evidence within the fuselage of the aircraft resulted in the findings of four human bone fragments which were identified as from tubular type bones such as the tibia or femur. A fragment of bone 10-1/2 inches long was found at station 350 in the hatrack area. This bone was identified as a left fibula, distal end, with the distal articulations intact. In the tissue attached to this bone fragment were pieces of olive-drab cloth, a brass plate similar to the front brass retainer plate of a Westclox "Travette" alarm clock, and miscellaneous other foreign material.

The wire fragments removed from the body of Mr. Frank were determined to be .025 inch diameter, low-carbon steel wire. Each wire particulate was tension necked at both
