A60282	Natural philosophy improven by new experiments touching the mercurial weather-glass, the hygroscope, eclipsis, conjunctions of Saturn and Jupiter, by new experiments, touching the pressure of fluids, the diving-bell, and all the curiosities thereof : to which is added some new observations, and experiments, lately made of several kinds : together with a true relation of an evil spirit, which troubled a mans family for many days : lastly, there is a large discourse anent coal, coal-sinks, dipps, risings, and streeks of coal, levels running of mines, gaes, dykes, damps, and wild-fire / by G.S.	Sinclair, George, d. 1696.	1683 (1683)	Wing S3855; ESTC R15622	205,371	320

about_o 20_o or_o 24_o ounce_n and_o lay_v it_o upon_o the_o say_a piece_n of_o wood_n but_o because_o it_o can_v well_o lie_v without_o fall_v off_o therefore_o nail_n upon_o the_o end_n and_o the_o

roof_n of_o a_o house_n in_o this_o position_n lay_v the_o iron_n bullet_n in_o the_o upmost_a end_n of_o it_o and_o then_o let_v they_o both_o pass_v from_o your_o finger_n the_o one_o end_n of_o the_o wood_n go_v foremost_a and_o you_o will_v find_v it_o swing_v towards_o the_o other_o side_n of_o the_o house_n and_o return_v again_o as_o a_o pendulum_n this_o motion_n if_o the_o wood_n be_v well_o guide_v in_o its_o vibration_n will_v last_v perpetual_o because_o in_o its_o move_n down_o the_o bullet_n be_v hurl_v from_o the_o one_o end_n of_o the_o wood_n to_o the_o other_o and_o hit_v

a_o pretty_a device_n to_o please_v the_o fancy_n that_o be_v many_o time_n deceive_v while_o thing_n be_v present_v to_o it_o by_o way_n of_o speculation_n yet_o upon_o trial_n and_o experience_n there_o will_v be_v find_v a_o unspeakable_a difficulty_n and_o it_o be_v such_o a_o one_o that_o a_o man_n will_v not_o ready_o think_v upon_o i_o say_v that_o when_o the_o wood_n be_v let_v go_v

the_o bullet_n be_v lay_v upon_o a_o very_a decline_a plain_a board_n whereupon_o no_o man_n can_v imagine_v a_o round_a body_n can_v lie_v yet_o all_o the_o time_n the_o board_n be_v in_o swing_v

in_o the_o place_n where_o you_o first_o place_v it_o this_o observation_n be_v not_o so_o much_o for_o a_o perpetual_a motion_n as_o for_o find_v out_o the_o reason_n of_o this_o pretty_a phenomenon_n namely_o what_o be_v the_o cause_n why_o the_o bullet_n that_o can_v lie_v upon_o a_o recline_a board_n while_o it_o be_v without_o motion_n shall_v now_o lie_v upon_o it_o while_o it_o

upon_o this_o board_n while_o it_o be_v swing_v it_o shall_v lie_v dead_a and_o without_o motion_n but_o no_o soon_o you_o stop_v the_o motion_n of_o the_o wood_n but_o assoon_o the_o bullet_n or_o

a_o stone_n be_v demit_v from_o the_o top_n of_o the_o mast_n it_o will_v move_v down_o in_o a_o line_n parallel_n with_o it_o and_o fall_v at_o the_o root_n some_o may_v think_v it_o ought_v not_o to_o fall_v direct_o above_o the_o place_n it_o hang_v over_o but_o rather_o some_o distance_n behind_o see_v the_o ship_n have_v advance_v so_o much_o bound_n in_o the_o time_n wherein_o the_o stone_n be_v come_v down_o likewise_o while_o a_o ship_n be_v under_o sail_n let_v a_o man_n throw_v up_o a_o stone_n never_o so_o high_a and_o never_o so_o perpendicular_a as_o to_o his_o apprehension_n yet_o it_o will_v fall_v down_o direct_o upon_o his_o head_n again_o notwithstanding_o that_o the_o ship_n have_v run_v perhaps_o her_o own_o length_n in_o the_o time_n while_o the_o stone_n be_v ascend_v and_o descend_v this_o experiment_n i_o find_v to_o hold_v true_a which_o may_v be_v easy_o try_v especial_o when_o a_o man_n be_v carry_v in_o a_o boat_n upon_o smooth_a water_n draw_v by_o a_o horse_n as_o be_v do_v in_o some_o place_n abroad_o let_v he_o therefore_o throw_v up_o a_o little_a stone_n or_o any_o heavy_a body_n and_o he_o will_v find_v it_o descend_v just_a upon_o his_o head_n notwithstanding_o that_o the_o horse_n that_o drag_n the_o boat_n be_v under_o a_o gallop_n and_o by_o this_o mean_n have_v advance_v ten_o or_o twelve_o pace_n in_o the_o time_n or_o while_o the_o boat_n be_v thus_o run_v let_v a_o man_n throw_v a_o stone_n towards_o the_o brink_n of_o the_o water_n in_o this_o case_n he_o shall_v not_o hit_v the_o place_n he_o aim_v at_o but_o some_o other_o place_n more_o forward_o this_o let_v we_o see_v that_o when_o a_o gun_n be_v fire_v in_o a_o ship_n under_o sail_n the_o bullet_n can_v hit_v the_o place_n it_o be_v direct_v to_o neither_o can_v a_o man_n ride_v with_o a_o full_a career_n and_o shoot_v a_o pistol_n hit_v the_o person_n he_o aim_v at_o but_o must_v sure_o miss_v he_o notwithstanding_o that_o though_o in_o the_o very_a instant_n of_o time_n wherein_o he_o fire_v the_o mouth_n of_o the_o pistol_n be_v most_o just_o direct_v for_o remedy_v whereof_o allowance_n must_v be_v grant_v in_o the_o aim_v at_o the_o mark_n while_o a_o man_n throw_v up_o a_o stone_n in_o a_o ship_n under_o sail_n it_o must_v receive_v two_o distinct_a impulse_n one_o from_o the_o hand_n whereby_o it_o be_v carry_v upward_o the_o other_o from_o the_o ship_n whereby_o it_o be_v carry_v forward_o by_o this_o mean_n the_o stone_n in_o go_v up_o and_o come_v down_o can_v describe_v a_o perpendicular_a but_o a_o crooked_a line_n either_o a_o parabola_fw-la or_o a_o line_n very_o like_a unto_o it_o neither_o can_v it_o describe_v a_o perpendicular_a line_n in_o come_v down_o from_o the_o top_n of_o the_o mast_n though_o in_o appearance_n it_o seem_v to_o do_v so_o but_o a_o crooked_a one_o which_o in_o effect_n must_v be_v the_o half_a of_o that_o which_o it_o describe_v in_o go_v up_o and_o come_v down_o for_o this_o same_o cause_n a_o stone_n throw_v horizontal_o or_o towards_o the_o brink_n of_o the_o water_n must_v describe_v a_o crooked_a line_n also_o and_o a_o pistol_n bullet_n shot_n while_o a_o man_n be_v ride_v at_o a_o full_a career_n must_v describe_v a_o line_n of_o the_o same_o kind_n note_v that_o a_o man_n walk_v from_o the_o stern_a of_o a_o ship_n to_o the_o head_n walk_v a_o long_a way_n than_o in_o walk_v from_o the_o head_n to_o the_o stern_a second_o a_o man_n may_v walk_v from_o the_o head_n to_o the_o stern_a and_o yet_o not_o change_v his_o place_n it_o be_v observable_a that_o a_o man_n under_o board_n will_v not_o perceive_v whether_o the_o ship_n be_v sail_v or_o not_o and_o can_v know_v when_o her_o head_n go_v about_o and_o it_o be_v strange_a that_o when_o a_o
