CONTENTS OF A BONE CAVE. 21 



the neck a distance equal to 1.25 transverse diameters of its base. The fossa 

 ligamenti teris is small but deep, and far removed from the edge of the head, 

 which is not connected with it by a groove. The condyles of the femur are rather 

 divergent. The condylar surfaces are continuous with the patellar. The external 

 bounding angle of the latter is a little more elevated than the internal. The latter 

 bounds a trochlear bevel which extends band-like along its inner side. This looks 

 as though the patella possessed a corresponding bevel which would include an angle 

 with its remaining inferior surface. 



The proximal portion of the tibia is characterized by the depth and width of the 

 longitudinal external fossa, which is bounded by the crest. The proximal articular 

 faces are not concave. The posterior face of this part of the shaft is narrow. The 

 distal portion of the shaft is marked on its external aspect by a narrow groove 

 which runs behind the fibular ridge, terminating where the latter begins to expand. 

 The angle rising from the anterior malleolar tuberosity becomes the internal edge 

 of the shaft, while the one which arises from the posterior one disappears on the 

 posterior face. The anterior and posterior edges of the external glenoid cavity 

 are equally produced, and the external and internal borders have the same relation. 

 The internal superior facet of the tibial articulation of the astragalus is half as 

 long and half as wide as the internal ; the area of the internal lateral face is still 

 smaller. There is a shallow fossa at the neck on the outer side. The navicular 

 facet is subround, and deeper than wide ; the facet for the additional proximal tarsal 

 bone is subtriangular with the apex posterior; its surface is moderately convex.
