A51544	Mechanick dyalling teaching any man, though of an ordinary capacity and unlearned in the mathematicks, to draw a true sun-dyal on any given plane, however scituated : only with the help of a straight ruler and a pair of compasses, and without any arithmetical calculation / by Joseph Moxon ...

a_o clock_n and_o iv_o a_o clock_n hour_n line_n if_o you_o will_v have_v the_o half_a hour_n and_o quarter_n hour_n or_o any_o other_o division_n of_o hour_n you_o must_v divide_v each_o six_o devision_n of_o the_o equinoctial_a into_o so_o many_o part_n as_o you_o intend_v and_o by_o a_o straight_a ruler_n lay_v to_o the_o centre_n of_o the_o equinoctial_a and_o those_o devision_n in_o

through_o those_o mark_n shall_v be_v the_o sub-devisions_a of_o the_o hour_n but_o you_o must_v remember_v to_o make_v all_o sub-devisions_a short_a line_n and_o near_o the_o verge_n of_o the_o

if_o it_o point_v westerly_a the_o plane_n decline_v from_o the_o south_n towards_o the_o east_n you_o may_v know_v if_o the_o plane_n be_v true_o erect_a or_o upright_a by_o apply_v one_o of_o the_o

the_o plane_n be_v upright_o but_o if_o it_o hang_v upon_o any_o of_o the_o intermediate_v degree_n it_o be_v not_o upright_o but_o incline_v or_o recline_v if_o you_o find_v it_o incline_v apply_v the_o side_n ab_fw-la to_o it_o and_o see_v what_o number_n of_o degree_n the_o plumb-line_n fall_v on_o for_o that_o number_n of_o degree_n count_v from_o the_o side_n ab_fw-la be_v the_o number_n of_o degree_n of_o inclination_n if_o you_o find_v the_o plane_n recline_v apply_v the_o side_n ad_fw-la to_o it_o and_o see_v what_o number_n of_o degree_n the_o plumb-line_n fall_v on_o for_o that_o

situation_n of_o all_o other_o sort_n of_o planes_n but_o for_o the_o make_v a_o dyal_n on_o this_o plane_n you_o must_v first_o draw_v a_o meridian_n line_n through_o the_o middle_n of_o the_o plane_n by_o apply_v a_o plumb-line_n to_o the_o middle_n of_o it_o till_o the_o plumbet_n hang_v quiet_o before_o it_o for_o than_o if_o the_o plumb-line_n be_v black_v for_o a_o white_a ground_n or_o chalk_v for_o a_o dark_a ground_n and_o strain_v as_o carpenter_n do_v their_o line_n you_o may_v with_o one_o stroke_n of_o the_o string_n on_o the_o plane_n describe_v the_o meridian_n line_n as_o a_o xii_o this_o meridian_n be_v also_o the_o substilar_a line_n then_o on_o the_o top_n of_o this_o meridian_n line_n as_o at_o a_o draw_v another_o line_n athwart_o it_o to_o cut_v it_o at_o

your_o plane_n as_o large_a as_o you_o can_v which_o by_o the_o meridian_n line_n and_o the_o east_n and_o west_n line_n will_v be_v divide_v into_o two_o quadrant_n one_o of_o these_o quadrant_n divide_v into_o 90_o degree_n as_o you_o be_v teach_v fol._n 12._o and_o from_o the_o substilar_a line_n count_v the_o compliment_n of_o the_o pole_n elevation_n which_o here_o at_o london_n where_o
