![grouped as a pair, forming a bisected elliptical figure, or they may divide again, producing either a row of cells or a cluster of three or four (Fig. 66). Since the cells change their positions with difficulty in the dense matrix, they are regularly found in very characteristic groups. It has been asserted that certain cartilage cells undergo mucoid degeneration and become lost in the matrix. In old cartilage dark spots, staining in- tensely with hasmatoxylin, are suggestive of such a process. Such cells must be carefully distinguished from tangential sections of the deeply staining pericapsular matrix.
