Paragraph

 1 1 |         have now to consider the parts which are useful to animals
 2 1 |        differences between these parts both in one and the same
 3 1 |       again by comparison of the parts of creatures of different
 4 3 |      feet; for at the joints the parts do in a sense lean upon
 5 3 |          the use of at least two parts of the body; one part so
 6 3 |        then that nothing without parts can move itself in this
 7 4 |         sensations, the opposite parts are the back.~All animals
 8 4 |         by the help of organized parts (I mean feet for example,
 9 4 |         differentiated into such parts, but make the differentiation
10 5 |       the superior and the front parts identically situated are
11 5 |          have the front and back parts identically situated, for
12 5 |   starting points to be in these parts; for the starting-point
13 5 |        say quite well that these parts are more honourable than
14 6 |   original of movement is in the parts on the right. Now every
15 6 |          in the place where both parts have opposed movements some
16 6 |        which connects the moving parts with one another. Further
17 6 |        of motion) of each of the parts must lie.~Clearly then if
18 6 |         of the opposite pairs of parts (right and left, that is,
19 6 |    movements the juncture of the parts in question.~Now before
20 6 |        centres of the individual parts are in pairs arranged coordinately
21 6 |          the centres in the four parts described.~
22 7 |          it be divided into more parts can live for any appreciable
23 7 |           in each of the severed parts, and can move in the same
24 7 |          the left of the forward parts is leading, the concavity
25 11|      must also have the superior parts of the body lighter, and
26 11|          relatively to the upper parts of his body than any other
27 11|     always dwarf-like, the upper parts of their bodies being longer
28 14| stumbling forwards with the hind parts as it were dragged after.
29 15|       erect, and has the forward parts of the body lighter than
30 15|       have the attachment of the parts in question oblique to the
31 15|         movement. For the hinder parts in this way would follow
32 18|         have legs on their under parts and near the wings; similarly,
33 18|       have two fins on the under parts and near the pectorals.
34 19|     animals, both in their other parts, and especially in those
