first_o a_o sepaparation_n from_o the_o place_n to_o which_o it_o be_v move_v be_v more_o quick_a &_o expedient_a by_o a_o right_a line_n forasmuch_o as_o crooked_a and_o circular_a line_n turn_v

the_o beginning_n this_o have_v be_v plain_o observe_v by_o experience_n that_o a_o stone_n let_v fall_v from_o a_o tower_n or_o high_a place_n will_v in_o motion_n grow_v swift_a and_o swift_a till_o it_o approach_v the_o ground_n or_o place_n whereon_o it_o fall_v the_o reason_n may_v be_v give_v from_o the_o air_n which_o resist_v so_o much_o the_o less_o by_o how_o much_o the_o body_n descend_v

towards_o the_o centre_n be_v not_o mere_o natural_a but_o mix_v with_o a_o violent_a motion_n this_o may_v easy_o be_v demonstrate_v because_o no_o point_n of_o any_o magnitude_n be_v move_v to_o

three_o these_o philosopher_n urge_v the_o necessity_n of_o nature_n to_o preserve_v the_o universe_n be_v much_o deceive_v in_o the_o manner_n and_o mean_n thereof_o true_a it_o be_v that_o all_o

the_o disorder_n and_o disharmony_n of_o one_o part_n shall_v prejudice_n and_o destroy_v the_o whole_a frame_n if_o they_o turn_v to_o the_o other_o part_n and_o grant_v this_o universal_a form_n to_o be_v internal_a many_o reason_n stand_v opposite_a for_o first_o i_o will_v demand_v whether_o this_o universal_a form_n be_v simple_a or_o compound_v it_o can_v be_v simple_a because_o it_o will_v always_o produce_v one_o simple_a and_o uniform_a effect_n but_o experience_n have_v t●ught_v the_o contrary_a because_o we_o shall_v not_o always_o find_v the_o air_n to_o descend_v but_o

it_o can_v well_o be_v call_v a_o compound_n form_n because_o all_o form_n the_o more_o universal_a they_o be_v the_o more_o simple_a they_o be_v to_o be_v account_v because_o the_o special_a

compose_v of_o essential_a part_n but_o rather_o a_o heap_n or_o mass_n collect_v and_o digest_v out_o of_o many_o body_n second_o the_o form_n be_v thus_o one_o individual_a will_v be_v singular_a or_o special_a not_o universal_a if_o they_o affirm_v that_o this_o form_n be_v diverse_a according_a to_o the_o diversity_n of_o the_o body_n it_o can_v be_v the_o cause_n of_o this_o motion_n or_o

in_o fear_n of_o rupture_n or_o dissolution_n but_o how_o can_v this_o form_n be_v bound_v within_o the_o limit_n of_o the_o aerial_a superficies_n perceive_v or_o feel_v this_o exigence_n of_o nature_n in_o other_o body_n whatsoever_o they_o can_v say_v in_o this_o be_v altogether_o uncertain_a and_o not_o warrant_v by_o any_o sound_a demonstration_n a_o second_o reason_n for_o the_o natural_a descent_n of_o the_o air_n may_v be_v draw_v from_o a_o possible_a supposition_n from_o which_o we_o may_v enforce_v a_o true_a conclusion_n let_v we_o suppose_v a_o portion_n of_o air_n by_o some_o violence_n to_o be_v carry_v above_o his_o proper_a orb_n as_o for_o example_n to_o the_o space_n which_o by_o our_o common_a philosopher_n be_v ascribe_v to_o the_o element_n of_o fire_n near_o the_o concave_a superficies_n of_o the_o moon_n i_o will_v here_o demand_v whether_o this_o portion_n of_o air_n thus_o transpose_v will_v ascend_v high_o or_o descend_v low_a or_o rest_v still_o in_o the_o same_o place_n it_o can_v not_o ascend_v high_o first_o because_o in_o this_o wise_a it_o shall_v be_v move_v far_o out_o of_o his_o own_o place_n whereas_o according_a to_o the_o

rove_v far_o off_o second_o this_o grant_v the_o air_n shall_v invade_v the_o place_n of_o the_o fire_n and_o so_o the_o element_n shall_v suffer_v a_o confusion_n which_o aristotle_n hold_v absurd_a three_o there_o can_v be_v imagine_v in_o that_o high_a orb_n any_o point_n or_o centre_n to_o which_o it_o shall_v direct_v his_o motion_n and_o therefore_o there_o be_v no_o such_o motion_n find_v or_o it_o must_v be_v very_o irregular_a if_o on_o the_o other_o side_n it_o be_v grant_v that_o such_o a_o portion_n of_o air_n so_o separate_v shall_v descend_v i_o ask_v again_o whether_o they_o
