for_o assure_o if_o the_o iron_n stand_v so_o in_o the_o northern_a hemisphere_n it_o will_v turn_v to_o the_o north_n and_o if_o in_o the_o southern_a hemisphere_n it_o will_v turn_v to_o the_o south_n for_o see_v the_o virtue_n of_o the_o loadstone_n proceed_v from_o the_o earth_n and_o the_o earth_n have_v different_a temper_n towards_o the_o north_n and_o towards_o the_o south_n pole_n as_o have_v be_v already_o declare_v the_o virtue_n which_o come_v out_o of_o the_o earth_n in_o the_o northern_a hemisphere_n will_v give_v to_o the_o end_n of_o the_o iron_n next_o it_o a_o inclination_n to_o the_o north_n pole_n and_o the_o earth_n of_o the_o southern_a hemisphere_n will_v yield_v the_o contrary_a disposition_n to_o the_o end_n which_o be_v near_a it_o the_o next_o question_n be_v why_o a_o loadstone_n seem_v to_o love_v iron_n another_o better_o than_o another_o loadstone_n the_o answer_n be_v because_o iron_n be_v indifferent_a in_o all_o its_o part_n to_o receive_v the_o impression_n of_o a_o loadstone_n whereas_o another_o loadstone_n receive_v it_o only_o in_o a_o determinate_a part_n and_o therefore_o a_o loadstone_n draw_v iron_n more_o easy_o than_o it_o can_v another_o loadstone_n because_o it_o find_v repugnance_n in_o the_o part_n of_o another_o loadstone_n unless_o it_o be_v exact_o situate_v in_o a_o right_a position_n beside_o iron_n seem_v to_o be_v compare_v to_o a_o loadstone_n like_o a_o more_o humid_a body_n to_o a_o dryer_n of_o the_o same_o nature_n and_o the_o difference_n of_o male_a and_o female_a sex_n in_o animal_n manifest_o show_v the_o great_a appetence_n of_o conjunction_n between_o moisture_n and_o dryness_n when_o they_o belong_v to_o body_n of_o the_o same_o species_n another_o question_n be_v that_o great_a one_o why_o a_o loadstone_n cape_v itself_o with_o steel_n take_v up_o more_o iron_n than_o it_o will_v do_v if_o it_o be_v without_o that_o cape_v another_o conclusion_n like_o this_o be_v that_o if_o by_o a_o loadstone_n you_o take_v up_o a_o iron_n and_o by_o that_o iron_n a_o second_o iron_n and_o then_o pull_v away_o the_o second_o iron_n the_o first_o iron_n in_o some_o position_n will_v leave_v the_o loadstone_n to_o stick_v to_o the_o second_o iron_n as_o long_o as_o the_o second_o iron_n be_v within_o the_o sphere_n of_o the_o lodestone_n activity_n but_o if_o you_o remove_v the_o second_o out_o of_o that_o sphere_n than_o the_o first_o iron_n remain_v within_o it_o though_o the_o other_o be_v out_o of_o it_o will_v leave_v the_o second_o and_o leap_v back_o to_o the_o loadstone_n to_o the_o same_o purpose_n be_v this_o other_o conclusion_n that_o the_o great_a the_o iron_n be_v which_o be_v entire_o within_o the_o compass_n of_o the_o lodestone_n virtue_n the_o more_o strong_o the_o loadstone_n will_v be_v move_v to_o it_o and_o the_o more_o forcible_o stick_v to_o it_o the_o reason_n of_o all_o these_o three_o we_o must_v give_v at_o once_o for_o they_o hang_v all_o upon_o on_o string_n and_o in_o my_o conceit_n neither_o gilbert_n nor_o galileo_n have_v hit_v upon_o the_o right_n as_o for_o gilbert_n he_o think_v that_o in_o iron_n there_o be_v original_o the_o virtue_n of_o the_o loadstone_n but_o that_o it_o be_v as_o it_o be_v asleep_a till_o by_o the_o touch_n of_o the_o loadstone_n it_o be_v awake_v and_o set_v on_o work_n and_o therefore_o the_o virtue_n of_o bath_n join_v together_o be_v great_a than_o the_o virtue_n of_o the_o loadstone_n alone_o but_o if_o this_o be_v the_o reason_n the_o virtue_n of_o the_o iron_n will_v be_v great_a in_o every_o regard_n and_o not_o only_o in_o stick_v or_o in_o take_v up_o whereas_o himself_o confess_v that_o a_o cape_v stone_n draw_v no_o further_a than_o a_o naked_a stone_n nor_o hardly_o so_o far_o beside_o it_o will_v continue_v its_o virtue_n out_o of_o the_o sphere_n of_o activity_n of_o the_o loadstone_n which_o it_o do_v not_o again_o see_v that_o if_o you_o compare_v they_o several_o the_o virtue_n of_o the_o loadstone_n be_v great_a than_o the_o virtue_n of_o the_o iron_n why_o shall_v not_o the_o middle_a iron_n stick_v close_o to_o the_o stone_n then_o to_o the_o further_a iron_n which_o must_v of_o necessity_n have_v less_o virtue_n galileo_n yield_v the_o cause_n of_o this_o effect_n that_o when_o a_o iron_n touch_v a_o iron_n there_o be_v more_o part_n which_o touch_v one_o another_o then_o when_o a_o loadstone_n touch_v the_o iron_n first_o because_o the_o refute_v loadstone_n have_v general_o much_o impurity_n in_o it_o and_o therefore_o divers_a part_n of_o it_o have_v no_o virtue_n whereas_o iron_n by_o be_v melt_v have_v all_o its_o part_n pure_a and_o second_o because_o iron_n can_v be_v smooth_v and_o polish_a more_o than_o a_o loadstone_n can_v be_v and_o therefore_o its_o superficies_n touch_v in_o a_o manner_n with_o all_o its_o part_n whereas_o divers_a part_n of_o the_o stone_n superficies_n can_v touch_v by_o reason_n of_o its_o ruggedness_n and_o he_o confirm_v his_o opinion_n by_o experience_n for_o if_o you_o put_v the_o head_n of_o a_o needle_n to_o a_o bare_a stone_n and_o the_o point_n of_o it_o to_o a_o iron_n and_o then_o pluck_v away_o the_o iron_n the_o needle_n will_v leave_v the_o iron_n and_o stick_v to_o the_o stone_n but_o if_o you_o turn_v the_o needle_n the_o other_o way_n it_o will_v leave_v the_o stone_n and_o stick_v to_o the_o iron_n out_o of_o which_o he_o infer_v that_o it_o be_v the_o multitude_n of_o part_n which_o cause_v the_o close_o and_o strong_a stick_v and_o it_o seem_v he_o find_v the_o same_o in_o the_o cape_n of_o his_o lodestone_n for_o he_o use_v flat_a iron_n for_o that_o purpose_n which_o by_o their_o whole_a plane_n do_v take_v up_o other_o iron_n whereas_o gilbert_n cape_v his_o with_o convex_a iron_n which_o not_o apply_v themselves_o to_o other_o iron_n so_o strong_o or_o with_o so_o many_o port_n as_o galileo_n do_v will_v not_o by_o much_o take_v up_o so_o great_a weight_n as_o he_o nevertheless_o it_o seem_v not_o to_o i_o that_o his_o answer_n be_v sufficient_a or_o that_o his_o reason_n convince_v for_o we_o be_v to_o consider_v that_o the_o virtue_n which_o he_o put_v in_o the_o iron_n must_v according_a to_o his_o own_o supposition_n proceed_v from_o the_o loadstone_n and_o then_o what_o import_v it_o whether_o the_o superficies_n of_o the_o iron_n which_o touch_v another_o iron_n be_v so_o exact_o plain_a or_o no_o or_o that_o the_o part_n of_o it_o be_v more_o solid_a than_o the_o part_n of_o the_o stone_n for_o all_o this_o conduce_v nothing_o to_o make_v the_o virtue_n great_a than_o it_o be_v since_o no_o more_o virtue_n can_v go_v from_o one_o iron_n to_o the_o other_o then_o go_v from_o the_o loadstone_n to_o the_o first_o iron_n and_o if_o this_o virtue_n can_v tie_v the_o first_o iron_n to_o the_o loadstone_n it_o can_v proceed_v out_o of_o this_o virtue_n that_o the_o second_o iron_n be_v tie_v to_o the_o first_o again_o if_o a_o paper_n be_v put_v betwixt_o the_o cap_n and_o another_o iron_n it_o do_v not_o hinder_v the_o magnetical_a virtue_n from_o pass_v through_o it_o to_o the_o iron_n but_o the_o virtue_n of_o take_v up_o more_o weight_n than_o the_o naked_a stone_n be_v able_a to_o do_v be_v thereby_o
