Also, the cuticle is of the same thickness. I can line the hairs up longitudinally and see that the tips of the scales match equally as far as protrusion and distance goes. This you couldn't show in the photographs. In order to show each and every characteristic in photographs, I would have to take 500 or 600 different photographs. Mr. EISENBERG. So these photographs are just as a general illustration of the kind of thing you see, rather than being given to the Commission as photographs from which the Commission is to make an identification? Mr. STOMBAUGH. That is correct. If I were to look at these photographs myself, I couldn't make an identification on them because I wouldn't be able to see enough and I would say this looks like this and this looks like this, but so what? What about the size of the pigments, what about the size of the scales, what about the thickness of the cuticle? I see a medulla here, I don't see a medulla over here. So you just couldn't see all the characteristics in a photograph. Mr. EISENBERG. But these characteristics you do see as you change the focus on the microscope? Mr. STOMBAUGH. Yes; these appear by looking through different areas of the hair shaft itself. Mr. EISENBERG. Now, getting to the microscope itself, suppose a person without experience looked through the microscope directly at the hairs. Would he be able to directly interpret the hairs--a known and a questioned hair--to see if they are probably identical, or does it take experience even to interpret what you see through a microscope? Mr. STOMBAUGH. This takes experience to interpret what you see. We get quite a few people through the lab on tours and every now and then I will set up some hairs. I had one man making a match with a dog hair and a human hair, and he said they came from the same person, because he couldn't interpret what he saw. He just thought he saw something which he didn't. Mr. EISENBERG. Mr. Stombaugh, could you tell from these hairs that you found in the blanket, and let me add parenthetically we sometimes have been calling this blanket a rug but we have been talking about the object---- Mr. DULLES. You call it a blanket, technically. Mr. EISENBERG. Technically a blanket, and it is Exhibit 140. This Exhibit 140, Mr. Stombaugh, could you tell whether these hairs had been pulled out or had fallen out? Mr. STOMBAUGH. These hairs had fallen out naturally. They have died and fallen from the body. This is a very normal occurrence. When one combs one's hair, ordinarily you will find one or two strands of hair on the comb, because hair is constantly being replaced in most people. Mr. EISENBERG. How can you tell it had fallen out? Mr. STOMBAUGH. From the shape of the root. Mr. EISENBERG. What is the difference of the shape of the root where a hair falls out and the shape of the hair of a root where it has been taken out artificially or unnaturally?
