Cope. ception, and that is the distal metacarpal and metatarsal keels of the Camelidce (figure 9). These animals confirm the probability of the keels being the effect of long-continued shocks, for they are the only Ruminants which have elastic pads on the inferior sides of their digits. That these processes may be displacements due to shocks long^ continued, is rendered probable by the structure of the bones themselves, (i) They project mostly in the direction of gravity. Constant jarring on the lower extremity of a hollow cylinder with soft (medullary) contents, and flexible end walls would tend to a decurvature of both inferior and superior adjacent end walls. If the side walls are wide and resistant, the projection will be median, and will be prolonged in the direction of the.
