 4 5 |            the part of the universe; quadrupeds, polypods, and footless

 7 7 |             move themselves like the quadrupeds, for they make the concave
 8 12|         directions, and further that quadrupeds bend their in opposite directions,
 9 12|      backwards, their legs forwards; quadrupeds their forelegs forwards,
10 12|             and for taking food. But quadrupeds which are also viviparous
11 12|             are like mankind. And so quadrupeds as well as men bend these

13 13|              only the elephant among quadrupeds and man if you consider
14 15|              legs in the same way as quadrupeds. For their natural construction
15 15|             is from the wings (as in quadrupeds from the forelegs). Flight
16 15|               as in the hind legs of quadrupeds. The reasons are the same
17 15|            in the case of viviparous quadrupeds.~If now we survey generally
18 15|             in the air.~Of oviparous quadrupeds all those that live in holes,
19 16|            polypods and none of them quadrupeds. And the reason why their

21 16|            and most of the oviparous quadrupeds. And the explanation is
22 17|             not bandy like oviparous quadrupeds and non-sanguineous polypods,
