"The <em>leg</em> consists, like the forearm, of two bones. The larger, a strong, three-sided bone with a sharp edge in front, is called the <em>tibia</em>. It is commonly known as the shin bone. The smaller bone, bound at both ends to the tibia, as a pin is to a brooch, is called the <em>fibula</em>, meaning a buckle or clasp. It is a long, slender bone on the outside of the leg, and is lower end forms the outer ankle." — Blaisedell, 1904
