with_o some_o magnetical_a vigour_n which_o bring_v into_o my_o mind_n what_o i_o former_o try_v with_o a_o piece_n of_o cork_n or_o such_o like_a body_n which_o i_o so_o order_v that_o by_o put_v a_o

it_o will_v instant_o turn_v its_o appropriate_a pole_n towards_o it_o and_o then_o run_v a_o tilt_n at_o it_o and_o this_o be_v only_o by_o take_v a_o dry_a cork_n and_o wet_v one_o side_n of_o it_o with_o one_o small_a stroke_n for_o by_o this_o mean_n gentle_o put_v it_o upon_o the_o water_n it_o will_v depress_v the_o superficies_n on_o every_o side_n of_o it_o that_o be_v dry_a and_o therefore_o the_o great_a pressure_n of_o the_o air_n be_v near_o those_o side_n cause_v it_o either_o to_o chase_v away_o or_o else_o to_o fly_v off_o from_o any_o other_o float_a body_n whereas_o
