 1 1 |    first is what are the fewest points of motion necessary to animal
 2 1 |   sanguineous animals have four points and not more, but bloodless
 3 1 |         at all; why in fine the points on which progression depends
 4 5 |    biped). In them, of the four points of motion, two are wings
 5 5 |     reasonable for the starting points to be in these parts; for
 6 7 |         by means of two or four points in their structure, or to
 7 7 |     animal can progress at more points than four, and that if it
 8 7 | anything so to progress at four points it must of necessity be
 9 7 |     made to move at two or four points, and even limbless Sanguinea
10 7 |        too move by dint of four points, whereby they achieve progression.
11 7 |         the tail the two hinder points. They look as if they moved
12 7 |         as if they moved at two points only, where they touch before
13 7 |    fluid makes up the remaining points.~
14 8 |        itself at more than four points. Granting this it is evident

16 10|      all Sanguinea move at four points, but merely at not more
