of_o one_o a_o other_o the_o hindermost_a can_v not_o choose_v but_o still_o follow_v on_o after_o the_o foremost_a and_o as_o it_o happen_v in_o filtration_n by_o a_o cotton_n cloth_n if_o some_o

such_o sort_n as_o the_o nose_n of_o a_o weathercock_n but_v itself_o into_o the_o wind_n now_o then_o it_o be_v know_v that_o the_o strong_a stream_n come_v direct_o from_o the_o north_n in_o the_o
