In concluding this part of the subject, which relates especially to the man-shaped Apes, some very obvious reflections occur. There is something very interesting as well as instructive and suggestive in the study of the proportions of the limbs to each other and to the body in the larger Apes, of which tlie Gordla is the highest in the scale, and in man. Tlie fingers in man hang down to below the middle of the thigh ; in the Gorilla they attain the knee ; in the Chimpanzee they reach Ijelow the knee; in the Orang they touch the ankle ; in the Siamang they reach the sole; and in some Gibbons the whole palm may be applied to the giound without the trunk being bent forward l)eyond its natural position on the legs. It is also found that in man the arm-bone exceeds in length each of the bones of the fore-ann in a marked mamier, and in the Gorilla and Chimpanzee it does so but slightly; the bones are equal in the Orangs, and very unequal in the Gibbons, those of the fore-ai-m being the longest. When the length of the arms down to the wi-ist is compared with that of the body, omitting the legs, there is not much ditierence between man and the Gorilla, but it inoriM The lower limbs are short in the (iorilla, and this the huge body—and the resemblance to the symnR scanty indeed. are pigmies. Consider the hand in the same manner. Man's perfect hand, \NTites Owen, is one of his peculiar l)hysical characters, and that perfection is mainly due to the differences of the first and the other four f
