and_o hard_o to_o be_v discern_v therefore_o very_o large_a instrument_n inclinatory_n be_v there_o to_o be_v use_v especial_o because_o the_o magnetical_a strength_n of_o the_o needle_n for_o that_o motion_n be_v there_o so_o strong_a and_o steady_a that_o it_o make_v some_o recompense_n for_o the_o slowuesse_n of_o his_o move_n and_o therefore_o i_o suppose_v that_o three_o in_o diameter_n will_v serve_v near_o the_o aequinoctial_a and_o fifteen_o near_o the_o pole_n and_o because_o this_o great_a one_o may_v be_v the_o less_o cumbersome_a you_o may_v cut_v off_o the_o circle_n at_o forty_o and_o five_o degree_n of_o each_o side_n of_o the_o zenith_n and_o nadir_n of_o the_o instrument_n and_o yet_o leave_v the_o needle_n scope_n enough_o for_o all_o latitude_n between_o sixty_o degree_n and_o the_o pole_n and_o for_o the_o the_o steady_a stand_n of_o the_o inclinatory_a instrument_n at_o the_o sea_n you_o may_v do_v thus_o about_o the_o middle_n of_o the_o instrument_n or_o rather_o somewhat_o above_o the_o middle_a let_v there_o be_v two_o round_a pin_n of_o brass_n about_o three_o quarter_n of_o a_o inch_n long_o issue_n out_o and_o in_o a_o box_n of_o a_o sail_a compass_n the_o inner_a circle_n be_v take_v away_o make_v of_o each_o side_n two_o half_a round_a notch_n in_o the_o outer_a circle_n there_o place_v the_o instrument_n upon_o those_o two_o pin_n the_o which_o must_v have_v towards_o their_o end_n little_n circle_n cut_v in_o that_o they_o slip_v not_o out_o of_o their_o ring_n that_o they_o be_v place_v in_o then_o will_v this_o instrument_n stand_v as_o steady_a even_o at_o sea_n as_o the_o sail_a compass_n will_v do_v for_o the_o motion_n of_o the_o inner_a circle_n be_v perform_v by_o the_o turn_n of_o those_o two_o pin_n in_o their_o notch_n and_o the_o outer_a circle_n be_v common_a unto_o they_o both_o always_o remember_v that_o you_o hang_v some_o pretty_a weight_n in_o the_o bottom_n of_o the_o instrument_n to_o make_v his_o motion_n more_o certain_a if_o the_o shadow_a of_o the_o box_n hinder_v your_o sight_n from_o discern_v the_o point_n that_o the_o needle_n stand_v at_o it_o be_v soon_o holpen_v with_o the_o light_n of_o a_o little_a wax_n candle_n put_v down_o unto_o it_o and_o yet_o this_o you_o ought_v to_o understand_v as_o aforesaid_a that_o the_o horizontal_n and_o inclinatory_a motion_n be_v but_o one_o and_o the_o self_n same_o effect_n of_o the_o touch_n of_o the_o loadstone_n and_o one_o and_o the_o self_n same_o needle_n will_v very_o well_o perform_v both_o motion_n namely_o the_o inclinatory_a needle_n not_o the_o horizontall_a because_o his_o place_n upon_o the_o pin_n make_v he_o very_o unfit_a for_o the_o incline_a motion_n but_o the_o inclinatory_a needle_n rest_v with_o one_o point_n of_o his_o axis_n the_o point_n of_o his_o axis_n be_v very_o sharp_a in_o his_o little_a hole_n his_o box_n be_v place_v parallel_n unto_o the_o horizon_n will_v perform_v the_o horizontall_a

on_o the_o sharp_a point_n of_o his_o pin_n but_o that_o the_o one_o be_v upward_o and_o the_o other_o downward_o &_o yet_o either_o of_o they_o be_v as_o fit_v for_o that_o motion_n as_o the_o
