the_o afore_o mention_v piece_n of_o earth_n can_v not_o receive_v from_o a_o loadstone_n any_o magnetical_a power_n but_o most_o certain_a it_o be_v and_o by_o many_o undoubted_a experiment_n

furthermore_o as_o among_o all_o the_o metal_n iron_n do_v incomparable_o more_o resemble_v the_o earth_n in_o substance_n then_o any_o other_o do_v it_o likewise_o do_v more_o participate_v with_o
