water_n run_v out_o in_o the_o same_o time_n to_o which_o i_o answer_v out_o of_o the_o same_o ground_n as_o before_z that_o because_o in_o run_v twice_o as_o fast_o there_o go_v out_o double_a the_o

this_o be_v certain_a that_o celerity_n to_o celerity_n have_v the_o proportion_n of_o force_n which_o weight_n have_v to_o weight_n it_o be_v evident_a that_o as_o in_o one_o case_n there_o must_v be_v weight_n in_o geometrical_a proportion_n so_o in_o theother_n case_n where_o only_a celerity_n make_v the_o variance_n the_o celerity_n must_v be_v in_o double_a geometrical_a proportion_n according_a as_o galileo_n find_v it_o by_o experience_n but_o to_o return_v to_o our_o main_a intent_n there_o be_v to_o be_v further_o note_v that_o if_o the_o subject_n strike_v be_v of_o a_o

for_o no_o force_n that_o once_o be_v in_o nature_n can_v be_v lose_v but_o must_v have_v its_o adequate_a effect_n one_o way_n or_o other_o let_v we_o then_o first_o suppose_v the_o body_n strike_v to_o be_v a_o hard_a body_n of_o no_o exceed_a bigness_n in_o which_o case_n if_o the_o stroke_n light_n perpendicular_o upon_o it_o it_o will_v carry_v such_o a_o body_n before_o it_o but_o if_o the_o body_n be_v too_o great_a and_o have_v its_o part_n so_o conjoin_v that_o they_o be_v weak_a than_o the_o stroke_n in_o this_o case_n the_o stroke_n drive_v one_o part_n before_o it_o and_o so_o

enter_v into_o such_o a_o body_n till_o it_o have_v spend_v its_o force_n so_o that_o now_o make_v up_o our_o account_n we_o see_v that_o a_o equal_a effect_n proceed_v from_o a_o equal_a force_n in_o all_o the_o three_o case_n though_o in_o themselves_o they_o be_v far_o different_a but_o we_o be_v apt_a to_o account_v that_o effect_n great_a which_o be_v more_o considerable_a to_o we_o by_o the_o

when_o it_o be_v sink_v in_o a_o current_n of_o wind_n or_o water_n you_o must_v remember_v that_o the_o dense_a body_n itself_o have_v a_o particular_a virtue_n of_o its_o own_o namely_o its_o

that_o his_o last_o argument_n ground_v upon_o the_o the_o swim_n of_o ice_n in_o water_n have_v no_o more_o force_n then_o if_o he_o will_v prove_v that_o a_o iron_n or_o earthen_a dish_n be_v
