Bone (don) [AS., ban, a bone]. A hard tissue that 

 constitutes the framework or skeleton of the body. 

 It is composed mainly of tri-calcium phosphate and 

 cartilage. Bone usually consists of a compact outer 

 mass covered with periosteum , surrounding a reticu- 

 lated inner structure that encloses a central cavity 

 filled with marrow. A transverse section of a long 

 bone shows bone-tissue to be composed of a number 

 of nearly circular zones, each having a central tube, 

 the Haversian canal, through which the blood circu- 

 lates. Surrounding the Haversian canal are concen- 

 trically arranged belts of oblong spaces called lacuna;. 

 Each lacuna is the outlet of a number of canaliculi, 

 through which the nutrition is conveyed to all parts 

 of the bone. A table of bones is appended. B. Ash,

 the instrument most commonly used as a test of bone- 

 conduction. Bone-conduction is lost or diminished
