Fig. 175.— Skeleton of gorilla viewed from in front. The bones of the gorilla are 

 Identical with those of man. Differences of proportion, however, are seen. Among 

 these differences, that of the relative length of arm and leg bones is most striking. The 

 Umb proportions of the human infant, however, tend to resemble those of the ape.
