    17. The BONES OF THE PROXIMAL PART OK THE TARSUS are always the largest and most important. The 'astragalus and os calcis, and probably also the naviciilarc, may be represented by a single bone, as ni many Lizards, and they may intimately fuse at an early age with the distal end of the tibia, as in almost all Birds. In this latter case these bones unite very early into one, which remains long distinct from the tibia, only in the Ostrich. Rhea, and Emeu ; and for some time after hatchmg in the Uorking Fowl.
