The Tibia (Plate VIII., Fig. 2). The tibia is short, straight, 

 and simple, slender in the middle, but much expanded at the 

 extremities. The proximal end is especially massive, with 

 deeply concave articular faces ; the internal cotylus is the 

 larger, and has its greatest diameter fore and aft, directly at 

 right angles to the greatest diameter of the external. 



The cotyli are separated by a smooth ridge, that is highest 

 at its posterior termination. The tuberosity is high and mas- 

 sive, with a wide depression on its top for the reception of 

 the ligament of the patella ; the sides are deeply pitted by 

 venous foramina. A section of the shaft at the lower part of 

 the tuberosity would be subtriangular ; while below it be- 

 comes more cylindrical, as it becomes smaller, reaching its 

 shortest diameter about three fifths down the shaft. Below 

 this it expands and forms the large subcircular distal end. 

 The articular face is concave, with a slight, smooth ridge run- 

 ing fore and aft on its internal side. The malleolus is broad 

 and low. 



The fibula is distinct, but very slender ; its proximal end 

 has a small circular face, which articulates with the tibia on a 

 facet developed on the bottom of a projection of the tuber- 

 osity ; the distal end is much flattened, but enters into the 

 ankle-joint.
