tedious_a for_o this_o they_o must_v consider_v that_o the_o whole_a frame_n of_o the_o firmament_n be_v carry_v round_o from_o the_o east_n to_o the_o west_n in_o .24_o hour_n so_o as_o there_o remain_v neither_o light_n nor_o mark_n but_o go_v round_o save_v only_o the_o .2_o pole_n of_o the_o world_n and_o these_o .2_o stand_v always_o fast_o but_o as_o i_o say_v before_o in_o the_o .9_o rule_v of_o he_o that_o go_v south_n or_o north_n do_v raise_v or_o lay_v the_o pole_n light_n and_o in_o like_a case_n of_o the_o equinoctial_a alter_v his_o parallel_n and_o cause_v the_o light_n of_o the_o firmament_n to_o alter_v the_o time_n of_o their_o shine_a or_o abide_v above_o our_o horizon_n so_o he_o that_o go_v direct_o east_n or_o west_n do_v neither_o raise_v nor_o lay_v the_o pole_n so_o that_o still_o the_o light_n of_o the_o firmament_n do_v make_v one_o manner_n of_o arch_n according_a to_o their_o latitude_n or_o declination_n but_o the_o go_v east_n or_o west_n do_v alter_v the_o meridian_n cause_v the_o planet_n to_o have_v their_o aspect_n at_o another_o hour_n or_o time_n alter_v the_o time_n of_o the_o change_n of_o the_o moon_n &_o also_o the_o time_n of_o the_o eclipse_n aspect_n which_o be_v necessary_a for_o all_o traveller_n by_o sea_n or_o by_o land_n therefore_o i_o think_v it_o needful_a to_o be_v speak_v of_o for_o as_o country_n have_v latitude_n from_o the_o pole_n so_o in_o like_a manner_n they_o have_v appoint_v longitude_n now_o therefore_o you_o may_v get_v the_o latitude_n with_o instrument_n longitude_n but_o the_o longitude_n you_o must_v bring_v from_o another_o place_n which_o you_o can_v do_v but_o with_o a_o globe_n or_o else_o a_o map_n or_o card_n and_o then_o you_o must_v measure_v from_o the_o meridian_n of_o the_o canary_n land_n otherwise_o call_v the_o fortunate_a island_n and_o in_o our_o latitude_n of_o london_n every_o .555_o mile_n which_o contain_v .15_o mile_n degree_n will_v answer_v to_o one_o hour_n of_o time_n and_o under_o the_o equinoctial_a .900_o mile_n to_o .15_o degree_n the_o degree_n be_v as_o long_o as_o the_o degree_n of_o latitude_n but_o towards_o the_o pole_n few_o and_o few_o till_o they_o come_v to_o nothing_o under_o the_o .2_o pole_n and_o now_o .37_o mile_n which_o be_v at_o london_n will_v answer_v to_o one_o degree_n of_o our_o latitude_n at_o .51_o or_o .52_o degree_n of_o elevation_n of_o the_o pole_n but_o the_o cause_n why_o the_o longitude_n be_v fetch_v from_o the_o canary_n land_n i_o know_v not_o but_o it_o be_v as_o i_o

know_v the_o better_a i_o will_v draw_v out_o certain_a of_o the_o chief_a place_n about_o this_o realm_n of_o england_n both_o their_o longitude_n and_o latitude_n by_o which_o you_o shall_v know_v what_o manner_n of_o arch_a the_o sun_n with_o the_o other_o light_n do_v make_v and_o also_o by_o the_o longitude_n you_o may_v know_v at_o what_o time_n the_o moon_n with_o any_o of_o the_o planet_n do_v make_v any_o aspect_n beside_o this_o the_o eclipse_n of_o the_o sun_n or_o moon_n with_o the_o change_n quarter_n and_o full_a moon_n by_o a_o true_a and_o exact_a ephemerides_n through_o all_o

to_o get_v the_o longitude_n you_o may_v do_v it_o at_o the_o time_n of_o the_o eclipse_n of_o the_o moon_n for_o that_o the_o eclipse_n of_o the_o moon_n be_v general_a so_o that_o she_o be_v above_o your_o horizon_n in_o any_o place_n upon_o the_o superficial_a part_n of_o the_o earth_n or_o sea_n consider_v as_o i_o say_v before_o by_o your_o almanac_n at_o that_o time_n when_o the_o eclipse_n shall_v happen_v the_o very_a hour_n and_o minute_n know_v also_o the_o place_n that_o your_o almanac_n be_v make_v for_o that_o do_v according_a to_o this_o rule_n with_o a_o precise_a instrument_n you_o shall_v take_v the_o alteration_n of_o the_o time_n with_o the_o hour_n and_o minute_n of_o the_o eclipse_n and_o furthermore_o you_o may_v know_v your_o longitude_n with_o the_o ephemerides_n by_o the_o conjunction_n of_o the_o moon_n with_o other_o fix_a star_n if_o it_o be_v not_o for_o one_o great_a infirmity_n and_o that_o be_v the_o paralex_n of_o the_o moon_n which_o the_o semidiametre_n of_o the_o earth_n do_v cause_n by_o the_o nearness_n of_o the_o moon_n unto_o the_o earth_n wherefore_o i_o will_v not_o any_o sea_n man_n shall_v be_v of_o that_o opinion_n that_o they_o may_v get_v any_o longitude_n with_o instrument_n sea._n therefore_o let_v no_o sea_n man_n trouble_v themselves_o with_o any_o such_o rule_n but_o according_a to_o their_o accustom_a manner_n let_v they_o keep_v a_o perfect_a account_n and_o reckon_v of_o the_o way_n of_o their_o ship_n whether_o the_o ship_n go_v to_o leward_n or_o make_v her_o way_n good_a consider_v always_o what_o thing_n be_v against_o they_o or_o with_o they_o as_o tide_n current_n wind_n or_o such_o like_a as_o for_o the_o rule_n of_o longitude_n it_o follow_v in_o the_o next_o chapter_n the_o .16_o chapter_n show_v how_o many_o mile_n will_v answer_n to_o one_o degree_n of_o longitude_n in_o every_o several_a latitude_n between_o the_o equinoctial_a and_o any_o of_o the_o a_o pole_n with_o the_o demonstration_n for_o that_o purpose_n and_o the_o diversity_n of_o aspect_n of_o the_o moon_n now_o by_o this_o rule_n shall_v i_o teach_v you_o how_o many_o mile_n will_v answer_v to_o one_o

the_o sun_n be_v under_o 50._o degree_n in_o height_n you_o may_v easy_o take_v the_o height_n because_o you_o may_v easy_o see_v or_o view_v the_o upper_a end_n and_o the_o nether_a end_n of_o the_o

because_o in_o long_a viage_n go_v far_o unto_o the_o westward_n or_o eastward_o the_o compass_n do_v vary_v to_o find_v the_o true_a meridian_n do_v this_o set_a the_o sun_n with_o your_o compass_n
