Chapter XXVI: Section 64: The simplest variety in this group is hyaline (i.e. glassy)

cartilage (gristle). In this the formative cells (the cartilage corpuscles) are enjellied in a clear structureless matrix (Figure XII.), consisting entirely of organic compounds accumulated by their activity. Immediately round the cell lies a capsule of newer material. Some of the cells have recently divided (1); others have done so less recently, and there has been time for the interpolation of matrix, as at 2. In this way the tissue grows and is repaired. A thin layer of connective tissue (see below), the perichondrium, clothes the cartilaginous structure.
