by_o the_o attraction_n of_o some_o great_a body_n that_o come_v near_o they_o if_o we_o shall_v suppose_v that_o the_o water_n be_v every_o where_o shut_v up_o within_o a_o solid_a orb_n lie_v on_o they_o so_o that_o there_o be_v no_o room_n or_o space_n leave_v for_o they_o to_o move_v in_o it_o be_v plain_a that_o in_o such_o a_o case_n there_o can_v be_v no_o tide_n or_o agitation_n of_o

violent_a and_o outrageous_a rain_n now_o if_o we_o consider_v
and_o consequent_o the_o one_o will_v descend_v when_o the_o other_o can_v as_o for_o example_n suppose_v a_o sphere_n of_o a_o inch_n diameter_n be_v put_v into_o a_o oily_a fluid_n who_o
