For the description of the skeleton of the monkeys of the old world, we shall select the two extremes, the Chimpanzee and the Mandrill, (fgs. 121 and 122). The vertebral column of Fig. Skeleton of the Clumpanzee. (After Owen.) the Chimpanzee presents but few deviations from that of the human subject. The number of true vertebras is the same, but an additional pair of ribs takes one from the lumbar, to be added to the dorsal or costal series. The spines of the seven cervical vertebra? are simple and elongated, not short and bifurcated as in the human subject ; that of the third vertebra is the shortest, with the exception of the atlas, where the spine is wanting. The bodies of the lumbar vertebras are proportion- ally smaller in the Chimpanzee than in man, where they are enlarged in reference to his erect position. This difference from the bi-.
