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.
