The microscopist or amateur, who shaves himself, need never resort to the trouble of embedding and cutting hairs in the microtome in order to secure very thin sections of the hair of the face. If he will first shave himself closely "with the hair," as the barbers say (i. e., in the direction of the natural growth of the hair), and afterwards lightly "against the hair" (in the opposite direction to above), he will find in the "scrapings" a multitude of exceedingly thin sections. The technique is very simple. The lather and "scrapings" are put into a saucer or large watch-glass and. carefully washed with clean water. This breaks down and dissolves the lather, leaving the hair sections lying on the bottom of the glass. The after-treatment is that usually employed in mounting similar objects.
