outer extremities which is bent over in the
backing process to form the projection at right
angles to the text block to accommodate the board.
2. The portion of a cowhide covering the shoulders
and neck of the animal together with the two
cheeks, and the leather produced therefrom. A

entirely eliminated during manufacture. 3. The top

include the bevel, beard, line, and side bearing.
4. A term sometimes applied to the upper, outer
corners of a leaf of a book. (151 , 161 , 313 )
