Mr. EISENBERG. Could you go on, please? Mr. DULLES. Just one second, off the record. (Discussion off the record.) Mr. DULLES. Back on the record. Mr. EISENBERG. You have presented at this point a chart labeled "Microphotograph of Oswald's Limb Hairs" on the left, and on the right two subcaptions, "Hair from Blanket" and "Hair from Oswald," and do these--were these photographs taken by you or under your supervision? Mr. STOMBAUGH. They were taken by me. Mr. EISENBERG. Are they accurate reproductions of the material which according to the captions they are photographs of? Mr. STOMBAUGH. Yes; they are. Mr. EISENBERG. I would like this admitted as 671, Mr. Chairman. Mr. DULLES. It will be admitted as 671. (Commission Exhibit No. 671 was marked, and received in evidence.) Mr. EISENBERG. Could you briefly discuss this exhibit? Mr. STOMBAUGH. Exhibit 671 is similar to Exhibit 672 in that both contain two photographs. The photograph on the left is an overall shot of Oswald's limb hairs. Mr. EISENBERG. That is the known? Mr. STOMBAUGH. That is the known from Oswald. The photograph on the right contains photographs of two hairs, in this same photograph, the hair on the right being a limb hair from Oswald, and the hair on the left being a hair removed from the blanket. Mr. EISENBERG. What is the magnification there, Mr. Stombaugh? Mr. STOMBAUGH. The magnification of these is approximately the same as in the previous submission, the one on the right being approximately 400 diameters and the one on the left 100 diameters. Now, the one on the right is a limb hair. A limb hair is much smaller in diameter than a pubic hair. That is why there will appear to be some slight change in the size of these hairs. I compared the limb hair from the blanket with the limb hair from Oswald which matched in all observable microscopic characteristics. The characteristics I found in this match were the color of the hair was light brown through its entire length, and the width of the hair shaft or the diameter was very fine. There was no fluctuation that one could readily see. The diameter of the hair shaft remained constant to the tip, where it diminished down to a point. The tips of the hairs were very sharp and no abrasion was noted. In other words, the tips of these limb hairs were not rounded as one ordinarily finds. This would indicate the hairs were very tough, the same as the pubic hairs were. Mr. EISENBERG. Are you describing now the known hairs? Mr. STOMBAUGH. These are known hairs and the match I made; both. Mr. EISENBERG. All right. Mr. STOMBAUGH. The scales were of medium size, had very slight protrusion, and there was very slight gapping in the pigmentation located in the cortex right against the cuticle of the hair. There was a fair amount of cortical fusi equally distributed throughout the hair shaft. This is not unusual in itself, but the amount of cortical fusi that I did find present is unusual.
