this_o noble_a instrument_n the_o one_o be_v that_o he_o will_v have_v a_o little_a box_n with_o a_o horizontical_a needle_n fasten_v unto_o the_o bottom_n of_o the_o inclinatory_a instrument_n for_o to_o direct_v the_o instrument_n unto_o the_o magnetical_a meridian_n and_o by_o his_o picture_n of_o the_o instrument_n his_o distance_n shall_v be_v but_o a_o little_a more_o than_o a_o inch_n whereby_o it_o be_v impossible_a but_o that_o the_o one_o needle_n must_v needs_o disturb_v the_o other_o so_o that_o neither_o of_o they_o can_v show_v a_o right_n yea_o although_o they_o be_v six_o inch_n asunder_o and_o more_o where_o the_o little_a box_n will_v give_v little_a direction_n for_o that_o purpose_n and_o beside_o that_o it_o be_v altogether_o unnecessary_a because_o the_o instrument_n will_v find_v the_o magnetical_a meridian_n by_o the_o least_o declination_n of_o the_o needle_n as_o be_v before_o show_v under_o the_o horizon_n without_o the_o help_n of_o any_o other_o the_o other_o error_n be_v this_o that_o he_o will_v have_v that_o end_n of_o the_o needle_n prepare_v to_o hang_v towards_o the_o north_n to_o be_v frame_v somewhat_o high_a than_o the_o other_o as_o it_o be_v usual_a in_o horozontical_a needle_n what_o workman_n soever_o observe_v this_o direction_n i_o will_v assure_v he_o that_o he_o shall_v loose_v his_o labour_n and_o as_o soon_o may_v he_o wash_v a_o blackamoor_n white_a as_o to_o make_v such_o a_o needle_n as_o that_o turn_n the_o reason_n be_v because_o it_o be_v only_o the_o magnetical_a virtue_n that_o work_v this_o effect_n the_o which_o over-weight_n in_o the_o either_o end_n of_o the_o needle_n in_o this_o motion_n do_v utter_o overthrow_v for_o horozontical_a needle_n in_o our_o northern_a climate_n it_o be_v necessary_a but_o for_o inclinatory_a needle_n it_o be_v utter_o untrue_a in_o all_o climate_n of_o the_o whole_a world_n wheresoever_o the_o motion_n of_o the_o horozontical_a needle_n be_v natural_o strong_a than_o the_o inclinatory_n for_o two_o cause_n the_o one_o be_v because_o his_o motion_n be_v only_o sideways_o the_o which_o be_v the_o easy_a for_o the_o magneaical_a motion_n to_o work_v in_o then_o that_o which_o be_v up_o and_o down_o and_o there_o be_v no_o difference_n which_o way_n you_o place_v the_o box_n wherein_o he_o stand_v so_o that_o it_o be_v parallel_n to_o the_o horizon_n whereas_o the_o inclinatory_a motion_n be_v in_o a_o vertical_a circle_n up_o and_o down_o and_o must_v stand_v only_o in_o his_o magnetical_a meridian_n to_o perform_v his_o office_n the_o other_o cause_n be_v because_o of_o the_o diversity_n of_o their_o place_n in_o their_o box_n for_o the_o horizontical_a needle_n stand_v more_o fit_a for_o his_o motion_n be_v place_v with_o his_o capital_a upon_o the_o point_n of_o a_o sharp_a pin_n than_o the_o inclinatory_n can_v do_v be_v place_v upon_o the_o two_o end_n of_o his_o axis_n although_o never_o so_o near_o the_o point_n but_o yet_o he_o will_v do_v very_o well_o if_o he_o be_v right_o fit_v and_o for_o navigation_n under_o either_o pole_n if_o there_o be_v any_o passage_n that_o way_n it_o be_v the_o only_a instrument_n of_o the_o world_n for_o where_o the_o horozontical_a needle_n or_o compass_n fail_v he_o be_v strong_a for_o the_o near_o the_o pole_n the_o strong_a he_o be_v in_o his_o â—otion_n contrariwise_o
