Note 20 — Chapter VII · STRUCTURE AND GROWTH OF SKIN.

It will be noted that the word “grain” is used by the tanner in at least three different senses, which are productive of much confusion. The extremely thin hyaline layer forms a natural glaze to the skin, and might well be spoken of as such; the form and arrangement of the papillæ and hair-pores might be called the “pattern” of the grain, leaving the use of the word “grain” itself restricted to the pars papillaris.
