 4  II,  2|        mass of water about the centre, from which all waters,
 5  II,  2|       this side of the earth’s centre and on that; for it has

 7  II,  2|      other side of the earth’s centre, they might return from
 8  II,  2|     descend only as far as the centre, for after that all motion
 9  II,  2|     For since they flow to the centre from which they issue forth
10  II,  5|        you draw lines from the centre of the earth they cut out
11  II,  5|         their vertex is at the centre of the earth. Two other

16 III,  5|  centre of the circle, and the centre of that circle (namely HI)
17 III,  5|     above the diameter AG, the centre will be at O on the line
18 III,  5|     the lower the pole and the centre of the circle will be.~In
