The tibia and fibula are united inferiorly, the tympanic bulla is hollow and the infra-orbital foramen narrow.
In both groups, for instance, the lower part of the hind-leg is formed by a long, slender cannon-bone, or metatarsus, terminating inferiorly in triple condyles for the three long and sharply clawed toes, the resemblance being increased by the fact that in both cases the small bone of the leg (fibula) is fused with the large one (tibia).
The patient is placed in the sitting position to facilitate the spread of anesthesia inferiorly to the stellate ganglion.
