Now in the lumbar vertebrae of apes near the base of the transverse process (G in fig. 4 18 ) on its lower surface is seen a sharp process (H in fig. 4) extending straight down and a depression cut for a nerve, making up its outer side and forming a kind of interval with the descending process into which the ascending process of the vertebra beneath enters. 19 Though it will not be possible to investigate the nature of this process in the ape for lack of a specimen, study the dog’s three lower thoracic
