the_o air_n in_o this_o our_o hemisphere_n be_v as_o it_o be_v strew_v over_o and_o sow_v with_o abundance_n of_o northern_a atom_n and_o that_o some_o brook_n of_o they_o be_v in_o station_n other_o in_o a_o motion_n of_o retrogradation_n back_o to_o their_o own_o north_n pole_n the_o southern_a atom_n which_o come_v upon_o they_o at_o the_o equator_fw-la do_v not_o only_o press_v in_o among_o

and_o with_o far_o great_a speed_n into_o the_o torrid_a zone_n than_o the_o northern_a atom_n can_v by_o reason_n of_o the_o sun_n approximation_n to_o the_o south_n and_o his_o distance_n from_o

then_o let_v we_o consider_v what_o these_o two_o stream_n thus_o incorporate_v must_v of_o necessity_n do_v in_o the_o surface_n or_o upper_a part_n of_o the_o earth_n first_o it_o be_v evident_a

of_o which_o we_o have_v sufficient_o discourse_v above_o now_o let_v we_o conceive_v that_o these_o steam_n find_v a_o body_n of_o a_o convenient_a density_n to_o incorporate_v themselves_o in_o in_o the_o way_n of_o density_n as_o we_o see_v fire_n do_v in_o iron_n and_o in_o other_o dense_a body_n and_o this_o not_o for_o a_o hour_n or_o two_o as_o happen_v in_o fire_n but_o for_o year_n as_o

of_o the_o nature_n of_o these_o steam_n which_o be_v draw_v from_o the_o pole_n that_o abound_v in_o cold_a and_o dryness_n for_o other_o that_o have_v not_o these_o quality_n do_v not_o contribute_v to_o loadstone_n the_o intend_a effect_n the_o body_n be_v apt_a to_o become_v a_o stone_n for_o so_o we_o see_v that_o cold_a and_o drought_n turn_v the_o superficial_a part_n of_o the_o earth_n into_o stone_n &_o rock_n &_o according_o wherever_o cold_a &_o dry_a wind_n reign_v powerful_o all_o such_o country_n be_v main_o rocky_a now_o then_o let_v we_o suppose_v this_o stone_n to_o be_v

turn_v it_o any_o way_n it_o will_v in_o this_o case_n certain_o follow_v that_o the_o end_n of_o the_o stone_n which_o in_o the_o earth_n lie_v towards_o the_o north_n pole_n will_v now_o in_o the_o air_n convert_v itself_o in_o the_o same_o manner_n towards_o the_o same_o point_n and_o the_o other_o end_n which_o lie_v towards_o the_o south_n turn_v by_o consequence_n to_o the_o south_n i_o

be_v strong_a than_o the_o opposite_a one_o now_o to_o explicate_v how_o this_o be_v do_v suppose_v the_o stone_n hang_v east_n and_o west_n free_o in_o the_o air_n the_o steam_n which_o be_v draw_v from_o the_o north_n pole_n of_o the_o earth_n range_v along_o by_o it_o in_o its_o course_n to_o the_o equator_fw-la and_o find_v in_o the_o stone_n the_o south_n steam_n which_o be_v grow_v innate_a to_o it_o very_o strong_a it_o must_v needs_o incorporate_v itself_o with_o it_o and_o most_o by_o those_o part_n of_o the_o steam_n in_o the_o stone_n which_o be_v strong_a which_o be_v they_o that_o

conceive_v the_o loadstone_n have_v a_o great_a strength_n to_o retain_v a_o iron_n lay_v upon_o it_o by_o its_o equator_fw-la then_o by_o its_o pole_n for_o to_o justify_v his_o assertion_n he_o

the_o intention_n of_o nature_n in_o all_o the_o body_n operation_n of_o the_o loadstone_n be_v to_o make_v a_o union_n betwixt_o the_o attractive_a and_o the_o atracted_a ●bodies_n which_o be_v evident_a out_o of_o the_o stick_n of_o they_o together_o as_o also_o out_o of_o the_o violence_n wherewith_o iron_n come_v to_o a_o loadstone_n which_o when_o it_o be_v draw_v by_o a_o powerful_a one_o be_v so_o great_a that_o through_o the_o force_n of_o the_o blow_n hit_v the_o stone_n it_o will_v rebound_v back_o and_o then_o fall_v again_o to_o the_o stone_n and_o in_o like_a manner_n a_o

back_o again_o the_o celerity_n wherewith_o it_o move_v make_v it_o retire_v itself_o too_o far_o on_o the_o other_o side_n and_o so_o by_o many_o undulation_n at_o last_o it_o come_v to_o rest_v direct_o opposite_a to_o the_o pole_n likewise_o by_o the_o declination_n by_o mean_n of_o which_o the_o iron_n to_o the_o stone_n or_o the_o stone_n to_o the_o earth_n approach_v in_o such_o a_o

to_o no_o other_o purpose_n but_o that_o the_o due_a end_n may_v come_v together_o and_o in_o general_a there_o be_v no_o doubt_n but_o one_o go_v to_o another_o be_v institute_v by_o the_o order_n of_o nature_n for_o their_o come_n together_o and_o for_o their_o be_v together_o which_o be_v but_o a_o perseverance_n of_o their_o come_n together_o the_o nine_o position_n be_v that_o the_o nature_n of_o a_o loadstone_n do_v not_o sink_v deep_o into_o the_o main_a body_n of_o the_o earth_n as_o to_o have_v the_o substance_n loadstone_n of_o its_o whole_a body_n be_v magnetical_a but_o only_o remans_n near_a the_o surface_n of_o it_o and_o this_o be_v evident_a by_o the_o inequality_n in_o virtue_n of_o the_o two_o end_n for_o if_o this_o magnetic_a virtue_n be_v the_o nature_n of_o the_o whole_a body_n both_o end_n will_v be_v equal_o strong_a for_o will_v the_o disposition_n of_o one_o of_o the_o end_n be_v different_a from_o the_o disposition_n of_o the_o other_o again_o there_o can_v be_v no_o variation_n of_o the_o tend_v towards_o the_o north_n for_o the_o bulk_n of_o the_o whole_a body_n will_v have_v a_o strength_n so_o eminent_o great_a than_o the_o prominence_n and_o disparity_n of_o hill_n or_o sea_n as_o the_o variety_n of_o these_o will_v be_v absolute_o insensible_a again_o if_o the_o motion_n of_o the_o loadstone_n come_v from_o the_o body_n of_o the_o earth_n it_o will_v be_v perpetual_o from_o the_o centre_n &_o not_o from_o the_o pole_n &_o so_o there_o can_v be_v no_o declination_n more_o in_o one_o part_n of_o the_o earth_n then_o in_o another_o nor_o will_v the_o loadstone_n tend_v from_o north_n to_o south_n but_o from_o the_o centre_n to_o the_o circumference_n or_o rather_o from_o the_o circumference_n to_o the_o centre_n and_o so_o we_o may_v learn_v the_o difference_n between_o the_o loadstone_n and_o the_o earth_n in_o their_o attractive_a operation_n to_o wit_n that_o the_o earth_n do_v not_o receive_v its_o influence_n from_o another_o body_n nor_o do_v its_o magnetic_a virtue_n depend_v of_o another_o magnetic_a agent_n that_o impress_n it_o into_o it_o which_o nevertheless_o be_v the_o most_o remarkable_a condition_n of_o a_o loadstone_n again_o the_o stong_a virtue_n of_o the_o loadstone_n be_v from_o pole_n to_o pole_n but_o the_o strong_a virtue_n of_o the_o earth_n be_v from_o the_o centre_n upward_o as_o appear_v by_o firefork_n gain_v a_o much_o great_a magnetic_a strength_n in_o a_o short_a time_n than_o a_o loadstone_n in_o a_o long_o neither_o can_v it_o be_v thence_o object_v that_o the_o loadstone_n shall_v therefore_o receive_v the_o earth_n influence_n more_o strong_o from_o the_o centerwards_o then_o from_o the_o pole_n of_o the_o earth_n which_o by_o its_o operation_n and_o what_o we_o have_v discourse_v of_o it_o be_v certain_a it_o do_v not_o since_o the_o bed_n where_o lodestone_n lie_v and_o be_v form_v be_v towards_o the_o bottom_n of_o that_o part_n or_o back_o of_o the_o earth_n which_o be_v imbue_v with_o magnetic_a virtue_n again_o this_o virtue_n which_o we_o see_v in_o a_o loadstone_n be_v substantial_a to_o it_o whereas_o the_o like_a virtue_n be_v but_o accidental_a to_o the_o earth_n by_o mean_n of_o the_o sun_n draw_v the_o northern_a and_o southern_a exhalation_n to_o the_o equator_fw-la earth_n the_o last_o position_n be_v that_o the_o loadstone_n must_v be_v find_v over_o all_o the_o earth_n and_o in_o every_o country_n and_o so_o we_o see_v it_o be_v both_o because_o iron_n mine_n be_v find_v in_o some_o measure_n almost_o in_o
