The Hair Under the Microscope.

Placed under a powerful microscope, the hair shows a surface covered with strong, coarse, jagged teeth and more strongly resembles a coarse, rough rasp. Dealers In human hair can tell In a moment whether the locks offered them have been cut off or combed out. They do this by rubbing the hairs through their fingers. If the hair has been cut from the head and has not been misplaced, it remains In its original position. If it has been pulled or combed out and putj together regardless of the direction lin which it grew, one portion of It will slip to the right and the other to the left. It does this because the jagged edges engage upon each other and pull In opposite directions. The philosophy of this is demonstrated by drawing a hair first one way then the other through the fingers, which slip easily toward the point, while considerable resistance is felt when the fingers are drawn from the point toward the end next the head.
