12 11|     the only erect animal, has legs longer and stouter relatively
13 11|     than any other animal with legs. What we observe in children
14 11|   hunchbacked yet stand on two legs because their weight is
15 11|      of the belly, so that the legs are attached at that point
16 12|    that without flexion in the legs or shoulders and hips no

18 12|    their arms backwards, their legs forwards; quadrupeds their
19 12|  forelegs forwards, their back legs backwards, and in like manner
20 12|       remain still. And so the legs must be jointed. And it
21 12|       natural way with his two legs, bends them forward for

23 12|      as well as men bend these legs forward in the manner described.
24 12|        the flexion of the hind legs were forwards the lifting

36 15|        and turtles, have their legs attached obliquely as their

45 17|     but rather set back. Their legs are short, and being set
46 17|  reason for their having short legs is that nature has added
