not_o in_o respect_n of_o the_o same_o place_n indeed_o but_o of_o diverse_a and_o therefore_o whether_o it_o be_v a_o flat_a horizontall_a or_o erect_v or_o else_o incline_v any_o way_n there_o will_v be_v but_o one_o kind_n of_o artifice_n in_o make_v of_o the_o same_o let_v we_o therefore_o now_o see_v in_o what_o manner_n a_o plain_a horizontall_a dial_n may_v be_v make_v for_o any_o place_n have_v therefore_o first_o prepare_v your_o flat_a dial_n ground_n parallel_n to_o the_o horizon_n draw_v a_o meridian_n on_o it_o as_o exact_o north_n and_o south_n as_o possible_o you_o can_v which_o do_v draw_v another_o east_n and_o west_n which_o must_v cross_v it_o at_o right_a angle_n the_o first_o of_o which_o line_n will_v show_v twelve_o and_o the_o other_o six_o of_o the_o clock_n both_o morning_n and_o evening_n then_o make_v a_o centre_n in_o the_o intersection_n of_o these_o two_o line_n describe_v a_o circle_n on_o your_o dial_n ground_n to_o what_o distance_n you_o please_v and_o then_o divide_v it_o as_o all_o other_o circle_n usual_o be_v into_o 360._o part_n and_o it_o will_v not_o be_v amiss_o to_o subdivide_v each_o of_o these_o into_o lesser_a part_n if_o it_o may_v convenient_o be_v do_v and_o now_o it_o only_o remain_v to_o find_v out_o the_o distance_n of_o the_o hour_n line_n in_o this_o circle_n for_o any_o latitude_n of_o place_n which_o that_o we_o may_v do_v by_o the_o use_n of_o the_o globe_n let_v it_o first_o be_v set_v to_o the_o latitude_n of_o the_o place_n assign_v and_o then_o make_v choice_n of_o some_o of_o the_o great_a circle_n in_o the_o globe_n that_o pass_v through_o the_o pole_n of_o the_o world_n as_o for_o example_n the_o equinoctial_a colour_n if_o you_o please_v and_o apply_v the_o same_o to_o the_o meridian_n in_o which_o situation_n it_o show_v midday_n or_o twelve_o of_o the_o clock_n then_o turn_v about_o the_o globe_n towards_o the_o west_n if_o you_o will_v till_o that_o fifteen_o degree_n of_o the_o aequator_fw-la have_v pass_v through_o the_o meridian_n you_o must_v mark_v the_o degree_n of_o the_o horizon_n that_o the_o same_o colour_n cross_v in_o the_o horizon_n for_o that_o point_n will_v show_v the_o distance_n of_o the_o first_o and_o eleven_o hour_n from_o the_o meridian_n both_o of_o which_o be_v distant_a a_o hour_n space_n from_o the_o meridian_n or_o line_n of_o midday_n then_o turn_v again_o the_o globe_n forward_o till_o other_o fifteen_o degree_n be_v pass_v the_o meridian_n the_o same_o colour_n will_v point_v out_o the_o distance_n of_o the_o ten_o hour_n which_o be_v two_o hour_n before_o noon_n and_o of_o the_o second_o hour_n after_o noon_n and_o in_o the_o same_o manner_n you_o may_v find_v out_o the_o distance_n of_o all_o the_o rest_n in_o the_o horizon_n allot_v to_o each_o of_o they_o fifteen_o degree_n in_o the_o aequator_fw-la cross_v the_o meridian_n but_o here_o you_o must_v take_v notice_n by_o the_o way_n that_o the_o begin_n of_o this_o account_n of_o the_o distance_n must_v be_v take_v from_o that_o part_n of_o the_o horizon_n on_o which_o the_o pole_n be_v elevate_v to_o wit_n from_o the_o north_n part_n of_o the_o horizon_n if_o the_o arctic_a pole_n be_v elevate_v and_o so_o likewise_o from_o the_o south_n part_n if_o the_o antarctick_a be_v elevate_v these_o distance_n of_o the_o hour_n
be_v thus_o note_v in_o the_o horizon_n of_o the_o globe_n you_o must_v afterward_o translate_v they_o into_o your_o plain_n allot_v for_o your_o dial_n ground_n reckon_v in_o the_o circumference_n of_o it_o so_o many_o degree_n to_o each_o hour_n as_o be_v answerable_a to_o those_o point_v out_o by_o the_o colour_n in_o the_o horizon_n and_o last_o have_v thus_o do_v the_o gnomon_n or_o stile_n must_v be_v erect_v where_o you_o be_v to_o observe_v this_o one_o thing_n which_o be_v indeed_o in_o a_o manner_n the_o chief_a and_o only_a thing_n in_o this_o art_n to_o be_v careful_o look_v unto_o namely_o that_o that_o edge_n or_o line_n of_o the_o gnomon_n which_o be_v to_o show_v the_o hour_n by_o its_o shadow_n in_o all_o kind_n of_o dial_n must_v be_v set_v parallel_n to_o the_o axis_n of_o the_o world_n that_o so_o it_o may_v make_v a_o angle_n of_o inclination_n with_o its_o plain_a ground_n equal_a ●…o_o that_o which_o the_o axis_n of_o the_o world_n make_v with_o the_o horizon_n now_o that_o the_o style_n be_v to_o stand_v direct_o to_o the_o north_n and_o south_n or_o in_o the_o meridian_n line_n be_v a_o thing_n so_o common_o know_v that_o it_o be_v to_o no_o purpose_n to_o mention_v it_o and_o this_o be_v the_o manner_n of_o make_v a_o dial_n on_o a_o plain_a horizontall_a ground_n now_o if_o you_o will_v make_v a_o plain_a erect_a dial_n perpendicular_a to_o the_o horizon_n which_o be_v common_o call_v a_o mural_a and_o respect_v either_o the_o north_n or_o south_n you_o must_v remember_v this_o one_o thing_n the_o ignorance_n whereof_o have_v drive_v those_o that_o common_o profess_v the_o art_n of_o dial_v into_o many_o trouble_n and_o difficulty_n this_o one_o thing_n i_o say_v be_v to_o be_v observe_v that_o that_o which_o be_v a_o erect_a dial_n in_o one_o place_n will_v be_v a_o horizontall_a in_o another_o place_n who_o zenith_n be_v distant_a from_o that_o place_n 90._o degree_n either_o northward_o or_o southward_o as_o for_o example_n let_v there_o be_v a_o erect_a dial_n make_v for_o any_o place_n who_o latitude_n be_v 25._o gr_n this_o be_v nothing_o else_o but_o to_o make_v a_o horizontall_a dial_n for_o the_o latitude_n of_o 38_o degree_n and_o if_o there_o be_v a_o erect_a dial_n make_v for_o the_o latitude_n of_o 27._o gr_n the_o same_o will_v be_v a_o horizontal_n dial_n for_o the_o latitude_n of_o 63_o degree_n the_o same_o proportion_n be_v to_o be_v observe_v in_o the_o rest_n and_o hence_o it_o manifest_o appear_v that_o a_o horizontal_n dial_n and_o a_o vertical_a be_v the_o same_o at_o the_o latitude_n of_o 45_o degree_n and_o so_o likewise_o by_o this_o rule_n may_v be_v make_v any_o manner_n of_o incline_v dial_n if_o so_o be_v that_o the_o quantity_n of_o the_o inclination_n be_v but_o know_v as_o for_o example_n if_o a_o dial_n be_v to_o be_v make_v on_o a_o plain_a ground_n who_o inclination_n be_v 10._o degree_n from_o the_o horizon_n southward_o and_o for_o a_o place_n who_o latitude_n be_v 52._o gr_n northward_o you_o must_v describe_v in_o that_o plain_a horizontall_a dial_n for_o the_o latitude_n of_o 62._o degree_n northward_o and_o if_o in_o the_o same_o latitude_n the_o dial_n ground_n do_v incline_v towards_o the_o north_n 16._o gr_n you_o must_v make_v a_o horizontall_a dial_n for_o the_o northern_a latitude_n of_o 36._o gr_n and_o thus_o much_o shall_v

of_o it_o which_o that_o end_n of_o the_o needle_n that_o be_v touch_v with_o the_o magnet_n always_o respect_n be_v direct_v towards_o the_o north_n so_o that_o consequent_o the_o opposite_a point_n

must_v always_o be_v place_v parallel_n to_o the_o horizon_n now_o i_o call_v these_o point_n fix_v only_o for_o doctrine_n sake_n not_o forget_v in_o the_o mean_a time_n that_o the_o magnetical_a

the_o needle_n always_o to_o look_v direct_o north_n and_o south_n now_o these_o line_n thus_o express_v in_o the_o mariner_n compass_n as_o the_o common_a intersection_n of_o the_o horizon_n and_o
