The lymphocytes which, according to their size, are known assmall and large, constitute approximately 20 per cent of the totalnumber of leucocytes in the normal adult blood, and from 40 to 60per cent in the infant. The small are from 5 to 8 microns in diame-ter, the large from 8 to 10 microns. Their protoplasm is stronglybasic, showing as a blue, narrow margin surrounding a clear or 448 DENTAL PATHOLOGY pale nucleus which lakes up most of the cell and which is round,or nearly so. The large and small lymphocytes are probably oneand the same cell, the larger probably being the older. Thelymph
