Quain's elements of anatomy . ith a few osteoblasts applied to the bone.

The jmmary osseous matter forming the original thin wall^ of the areolse, andproduced by calcification of the cartilaginous matrix, is decidedly granular, andhas a daik appearance ; the subsequent or secondanj dejjosit on the other hand isquite transparent, and of a uniform, homogeneous aspect. This secondary depositbegins to cover the granular bone a very short distance below the siu-face ofossification (see fig. 108), and, as ali-eady stated, increases in thickness furtherdown. Fig. 107.
