 8 I  |          should not be so, for all bodies do fall equally fast to
 9 I  |        that force which causes all bodies to attract each other when
10 II |     occasion, I explained that all bodies attracted each other, and
11 II |          when we brought these two bodies [two equal-sized ivory balls
12 II |       respect to the distance that bodies are apart. If I take one
13 II |           they are right) that two bodies attract each other inversely
14 II |           to the planets and other bodies, and tell why they move
15 II |          and go a step father. All bodies attract each other at sensible
