contain_v one_o a_o fly_n another_o a_o spider_n a_o three_o a_o straw_n and_o each_o of_o the_o rest_n some_o such_o other_o thing_n and_o it_o seem_v not_o impossible_a that_o the_o contract_n of_o the_o external_a air_n may_v put_v the_o part_n of_o such_o small_a body_n into_o a_o new_a motion_n whereby_o some_o voluble_a corpuscle_n that_o hinder_v their_o reciprocal_a adhesion_n may_v be_v exclude_v and_o the_o particle_n themselves_o press_v or_o otherwise_o dispose_v into_o a_o close_a order_n and_o we_o find_v that_o some_o oyl-colour_n after_o they_o be_v bring_v to_o their_o due_a
