hock. The same bones are joined by an interosseous ligament, which 

 forms the roof of that canal. 



The Anterior Cttboido-cunean Ligament connects the cuboid and cunei- 

 form magnum bones below the entrance to the above-mentioned vas- 

 cular canal ; and an interosseous cuhoido-cunean ligament forms the floor 

 of the canal. 



The Scapkoido-cunean Interosseous LigaTnent joins the scaphoid and 

 two cuneiform bones. 



The Intercunean Ligament passes between the two cuneiforms. 



These and the other interosseous ligaments are concealed in the 

 interstices between the different bones which they bind together, and 

 cannot be fully seen imtil the bones are separated. 



Synovial Membranes. — "There is a proper synovial membrane for the 

 facets by which the scaphoid and cuneiform magnum bones corre- 

 spond ; this synovial membrane belongs also to the two cuboido- 

 soaphoid, and posterior cuboido-cunean arthrodite. The anterior 

 cuboido-scaphoid diarthrosis receives a prolongation from the synovial 

 memibrane between the os calois and astragalus on the one hand, 

 and the cuboid and scaphoid on the other. The play of the 

 anterior cuboido-cunean, and inter-cunean facets is facilitated by two 

 prolongations of the tarso-metatarsal synovial membrane." — Chauveau. 



THE TAESO-METATAHSAL ARTIOULATION. 



An Interosseous Ligament binds the heads of the metatarsal bones to 

 the tarsal bones with which these articulate, and the union is further 

 secured by many of the ligaments, already dissected, which, though 

 they belong to the hook, have points of insertion into the heads of the 

 metatarsal bones. 



Synovial Membrane. — This not only supplies the tarso-metatarsal joint, 

 but also ascends between the two cuneiforms, and into the anterior facet 

 between the cuboid and cuneiform magnum. It also descends into the 

 articulations between the large and small metatarsal bones. 



Directions. — For a description of the remaining joints of the hind limb 

 (except the hip), turn to the description of the corresponding articula- 

 tions of the fore limb (page 50). The hip-joint is described with the 

 pelvis, at page 338.
