The numberof sesamoid bones increases inaccordance with age and theamount of physical labor done. Composition of Bone. — Bone iscomposed of animal and mineralmatter, the latter of which ischiefly phosphate and carbonateof lime. By placing a. slenderbone from any animal in watercontaining one tenth part of nitricacid or hydrochloric acid, themineral matter will be so com-pletely dissolved out in four daysthat the bone will be as limber ascartilage. From another bone theanimal matter may be removed b
