subtraction_n of_o air_n and_o many_o the_o like_a experiment_n make_v by_o mr._n boyle_n a_o honourable_a member_n of_o this_o society_n in_o that_o pneumatick_a engine_n of_o his_o invention_n but_o

levity_n be_v but_o comparative_o so_o be_v only_a gravity_n in_o a_o less_o degree_n they_o take_v levity_n to_o be_v positive_a and_o gravity_n to_o be_v but_o a_o less_o degree_n of_o levity_n and_o consequent_o those_o heavy_a body_n not_o to_o affect_v a_o descent_n but_o to_o be_v thrust_v down_o by_o body_n more_o light_a which_o more_o strong_o affect_v a_o high_a place_n but_o against_o these_o the_o one_o and_o the_o other_o i_o apprehend_v as_o to_o philosophy_n these_o inconvenience_n which_o to_o i_o seem_v cogent_a argument_n if_o this_o motion_n up-ward_n be_v natural_a it_o must_v be_v either_o a_o averseness_n from_o the_o centre_n as_o the_o terminus_n à_fw-fr quo_fw-la or_o a_o propension_n to_o some_o other_o place_n as_o the_o terminus_n ad_fw-la quem_fw-la if_o they_o say_v the_o former_a it_o be_v true_a that_o then_o b_o oughts_z to_z move_z from_o c_o in_o perpendicular_a line_n as_o cba_n fig._n 26_o and_o the_o phaenomenon_n do_v not_o

that_o somewhat_o shall_v thrust_v it_o thence_o by_o somewhat_o more_o forcible_o press_v between_o than_o that_o it_o shall_v fly_v thence_o without_o affectation_n of_o any_o other_o place_n but_o if_o they_o say_v as_o seem_v more_o rational_a if_o levity_n be_v the_o positive_a principle_n that_o it_o be_v a_o affectation_n of_o some_o high_a place_n suppose_v a_o while_o b_o be_v just_a between_o c_o and_o a_o the_o motion_n it_o be_v true_a will_v be_v in_o the_o perpendicular_a cba_n as_o the_o straight_a way_n thither_o but_o if_o it_o be_v any_o where_o else_o as_o at_o d_o then_o its_o motion_n to_o a_o will_v not_o be_v in_o dce_n the_o perpendicular_a but_o in_o da_fw-la a_o oblique_a line_n which_o be_v contrary_a to_o all_o experience_n for_o the_o same_o light_a body_n wherever_o it_o be_v move_v upward_o in_o a_o perpendicular_a as_o well_o as_o a_o heavy_a body_n in_o a_o perpendicular_a downward_o and_o if_o to_o avoid_v this_o they_o will_v say_v that_o

move_n to_o a_o place_n if_o it_o be_v indifferent_a whether_o to_o a_o or_o to_o e_o but_o rather_o a_o move_n from_o a_o place_n that_o be_v to_o be_v as_o far_o from_o c_o as_o it_o can_v which_o be_v the_o former_a branch_n of_o the_o supposition_n and_o against_o which_o we_o do_v before_o urge_v the_o former_a inconvenience_n which_o make_v it_o not_o likely_a that_o there_o be_v any_o such_o thing_n as_o positive_a lightness_n at_o all_o since_o it_o will_v be_v hard_a to_o assign_v what_o shall_v be_v the_o terminus_n ad_fw-la quem_fw-la which_o such_o a_o mover_n aim_v at_o but_o

the_o balance_n be_v find_v so_o to_o be_v not_o light_a than_o before_o therefore_o its_o positive_a quality_n be_v heaviness_n not_o lightness_n the_o positive_a gravity_n of_o the_o air_n be_v
