varieties prevail at the periphery of the periosteum, blending 

 with neighboring tissues. The ribbons are separated from each 

 other in a longitudinal direction by straight so-called elastic 

 fibers, which render each ribbon rhomb-shaped. At the corners of 

 the rhomb, the elastic fibers anastomose with each other in acute 

 angles. A broad ribbon is not infrequently subdivided by elastic 

 fibers into smaller rhombs.

The protoplasmic bodies are spindle-shaped in the striated, 

 rhomboidal in the rhomb-shaped, and oblong in the ribboned 

 basis-substance. In the interstices between the layers similar
