Proceeding in this way,Gerlach was unable to see any blue channels in the cartilage matiix, whileArnold, on the other hand, obtained results from which he was led to infer theexistence of minute cleft-Uke spaces throughout the matrix connected by fineradiating canaliculi on the one hand with the lymphatics in the perichondrium,and on the other hand with the ceU-spaces of the cartilage. Such is the structure of hyahne cartilage in general, hut it is more orless modified in different 80 CARTILAGE. In articular cartilarie, the matrix in a thin section appears dim, likeground glass, having sometimes an almost granular aspect. The cellsand cell-groups are smaller and more dispersed, as a rule, than in rib-car-tilage. As is the case also with the cartilage of the ribs, the groups areflattened at and near to the surface, and lie parallel with it (fig. 81, a) ; Fig. 81. in I -^ a 3^ I -^ o
