the_o description_n of_o the_o horological_a ring-dyall_n which_o show_v the_o hour_n of_o the_o day_n in_o any_o part_n of_o the_o world_n it_o be_v project_v our_o of_o two_o great_a circle_n of_o the_o sphere_n a_o axis_n and_o a_o little_a ring_n to_o hang_v it_o by_o the_o great_a circle_n be_v the_o meridian_n one_o quadrant_a or_o quarter_n of_o it_o be_v divide_v into_o 90._o degree_n to_o set_v it_o to_o the_o latitude_n of_o the_o place_n wherein_o you_o be_v on_o the_o other_o side_n of_o this_o meridian_n be_v a_o quadrant_a of_o altitude_n to_o take_v the_o height_n of_o the_o sun_n whereby_o you_o may_v find_v the_o latitude_n the_o lesser_a circle_n be_v the_o aequinoctial_a divide_v into_o 24._o equal_a part_n or_o hour_n with_o their_o half_n and_o quarter_n which_o

place_n the_o little_a ring_n be_v make_v to_o slide_v along_o the_o quadrant_n with_o a_o small_a tooth_n to_o set_v it_o to_o the_o latitude_n which_o if_o you_o know_v not_o you_o may_v find_v it_o in_o this_o manner_n 1._o example_n suppose_v the_o latitude_n be_v unknown_a to_o you_o and_o you_o will_v find_v it_o out_o yourself_o admit_v on_o the_o 11_o of_o june_n you_o must_v by_o the_o former_a rule_n find_v the_o declination_n of_o the_o sun_n for_o that_o day_n which_o will_v be_v 23._o degree_n and_o a_o half_a or_o 30._o minute_n northwards_o then_o take_v the_o height_n of_o the_o sun_n at_o 12._o a_o clock_n which_o near_o about_o london_n will_v be_v 62._o degree_n subtract_v the_o declination_n 23._o degree_n 30._o minute_n out_o of_o 62._o gr_n and_o the_o remainder_n will_v be_v 38._o degree_n 30._o minute_n the_o height_n of_o the_o aequinoctial_a take_v this_o 38._o gr_n 30._o from_o 90._o degree_n the_o remainder_n will_v be_v 51._o deg_n 30._o min._n the_o

from_o 90._o gr_n leaf_n 51._o gr_n 30._o min._n as_o before_o how_o to_o find_v the_o hour_n of_o the_o day_n you_o must_v set_v the_o tooth_n to_o the_o height_n of_o the_o pole_n or_o latitude_n and_o the_o hole_n in_o the_o plate_n you_o must_v slide_v to_o the_o day_n of_o the_o month_n then_o draw_v out_o the_o aequinoctial_a or_o lesser_a circle_n and_o as_o near_o as_o you_o can_v guess_v at_o the_o hour_n and_o turn_v the_o hole_n to_o it_o then_o hold_v the_o instrument_n by_o the_o little_a ring_n and_o move_v it_o till_o the_o sun_n shine_v through_o the_o hole_n upon_o

world_n how_o to_o find_v the_o elevation_n of_o the_o pole_n or_o latitude_n of_o the_o place_n first_o set_v the_o hole_n in_o the_o move_a piece_n to_o the_o day_n of_o the_o month_n then_o turn_v the_o other_o side_n and_o against_o the_o hole_n you_o shall_v find_v the_o sun_n decliration_n for_o that_o day_n the_o same_o day_n you_o must_v take_v the_o meridian_n altitude_n of_o the_o sun_n which_o will_v be_v at_o twelve_o a_o clock_n every_o day_n and_o may_v be_v perform_v by_o this_o instrument_n thus_o put_v a_o pin_n into_o the_o hole_n which_o you_o shall_v find_v in_o the_o
