more_o and_o its_o substance_n less_o that_o contrariwise_o dense_a where_o the_o substance_n be_v more_o and_o the_o quantity_n less_o now_o if_o we_o look_v into_o the_o propriety_n of_o the_o body_n we_o have_v name_v or_o of_o any_o other_o we_o shall_v see_v they_o all_o follow_v clear_o out_o of_o these_o definition_n for_o first_o that_o one_o be_v more_o diffuse_v a_o other_o more_o

this_o again_o follow_v that_o in_o rare_a body_n there_o be_v less_o resistance_n to_o the_o motion_n of_o a_o other_o body_n through_o it_o then_o in_o dense_a one_o and_o therefore_o a_o like_a force_n pass_v more_o easy_o through_o the_o one_o then_o through_o the_o other_o again_o rare_a body_n be_v more_o penetrative_a and_o active_a then_o dense_a one_o because_o be_v by_o their_o overproportion_n of_o quantity_n easy_o divisible_a into_o small_a part_n they_o can_v run_v into_o every_o little_a poor_a and_o so_o incorporate_v themselves_o better_o into_o other_o body_n then_o more_o dense_a one_o can_v light_a body_n likewise_o must_v be_v rare_a because_o most_o divisible_a if_o other_o circumstance_n concur_v equal_o thus_o you_o see_v decipher_v unto_o your_o hand_n the_o first_o division_n of_o body_n flow_v from_o quantity_n as_o it_o be_v ordain_v to_o substance_n for_o the_o composition_n of_o a_o body_n for_o since_o the_o definition_n of_o a_o body_n be_v

touch_v thus_o on_o metaphysic_n to_o explicate_v the_o nature_n of_o these_o two_o kind_n of_o body_n for_o metaphysic_n be_v the_o science_n above_o physics_n it_o belong_v unto_o she_o to_o

that_o the_o essence_n of_o rarity_n and_o density_n stand_v in_o the_o proportion_n of_o quantity_n to_o substance_n if_o we_o believe_v aristotle_n the_o great_a master_n that_o ever_o be_v of_o

an_o other_o argument_n of_o galileo_n be_v as_o bad_a as_o this_o when_o he_o endeavour_v to_o prove_v that_o all_o body_n go_v of_o a_o like_a velocity_n because_o it_o happen_v that_o a_o light_a body_n in_o some_o case_n go_v fast_a than_o a_o heavy_a body_n in_o a_o other_o case_n as_o for_o example_n in_o two_o pendant_n whereof_o the_o light_a be_v in_o the_o begin_n of_o its_o motion_n

their_o weight_n yet_o to_o do_v the_o like_a between_o ice_n and_o water_n if_o ice_o be_v throughout_o full_a of_o air_n as_o of_o necessity_n it_o must_v be_v we_o believe_v impossible_a and_o therefore_o it_o may_v be_v light_a in_o the_o bulk_n than_o water_n by_o reason_n of_o the_o great_a pore_n cause_v in_o it_o through_o the_o shrink_n up_o of_o the_o part_n of_o water_n together_o which_o pore_n must_v then_o necessary_o be_v fill_v with_o air_n and_o yet_o every_o part_n by_o itself_o in_o which_o no_o air_n be_v be_v heavy_a than_o so_o much_o water_n and_o by_o this_o it_o appear_v that_o his_o last_o argument_n ground_v upon_o the_o swim_n of_o ice_n in_o water_n have_v no_o more_o force_n than_o if_o he_o will_v prove_v that_o a_o iron_n or_o a_o earthen_a dish_n

more_o dense_a than_o it_o be_v alone_o and_o according_o we_o see_v that_o ice_o half_o thaw_v for_o then_o much_o of_o the_o air_n be_v drive_v out_o and_o the_o water_n begin_v to_o fill_v the_o

such_o notion_n as_o i_o must_v busy_v myself_o about_o in_o this_o discourse_n therefore_o i_o will_v presume_v to_o borrow_v they_o from_o the_o latin_a school_n where_o there_o be_v much_o ado_n about_o they_o i_o will_v express_v the_o difference_n between_o body_n that_o under_o the_o same_o measure_n and_o outward_a bulk_n have_v a_o great_a thinnenesse_n and_o expansion_n or_o thickness_n

be_v evident_a unto_o we_o that_o there_o be_v different_a sort_n of_o body_n of_o which_o though_o you_o take_v equal_a quantity_n in_o one_o regard_n yet_o they_o will_v be_v unequal_a in_o a_o other_o their_o magnitude_n may_v be_v the_o same_o but_o their_o weight_n will_v be_v different_a or_o contrariwise_o their_o weight_n be_v equal_a their_o outward_a measure_n will_v not_o be_v so_o take_v a_o pint_n of_o air_n and_o weigh_v it_o against_o a_o pint_n of_o water_n and_o you_o will_v see_v the_o balance_n of_o the_o last_o go_v down_o amain_o but_o if_o you_o drive_v out_o the_o air_n by_o fill_v the_o pint_n with_o lead_n the_o other_o pint_n in_o which_o the_o water_n be_v will_v rise_v again_o as_o fast_o which_o if_o you_o pour_v out_o and_o fill_v that_o pint_n with_o quicksilver_n you_o will_v perceive_v the_o lead_n to_o be_v much_o light_a and_o again_o you_o will_v find_v a_o pint_n of_o gold_n heavy_a than_o so_o much_o mercury_n and_o in_o like_a manner_n if_o you_o take_v away_o of_o the_o heavy_a body_n till_o they_o agree_v in_o weight_n with_o the_o light_a they_o will_v take_v up_o and_o fill_v different_a proportion_n and_o part_n of_o the_o

whereby_o they_o be_v make_v one_o but_o to_o deduce_v this_o more_o particular_o immediate_o let_v we_o consider_v that_o all_o the_o little_a surface_n by_o which_o one_o hard_a body_n may_v be_v conceive_v to_o touch_v a_o other_o as_o for_o example_n when_o a_o stone_n lie_v upon_o a_o stone_n must_v of_o necessity_n be_v either_o plane_n or_o concave_a or_o convexe_v now_o if_o a_o plane_n

air_n which_o be_v in_o the_o middle_n must_v have_v flee_v quite_o out_o from_o between_o the_o two_o surface_n as_o soon_o as_o any_o part_n of_o the_o surface_n do_v touch_v that_o be_v as_o soon_o as_o the_o air_n which_o be_v between_o the_o utmost_a edge_n of_o the_o surface_n do_v fly_v out_o and_o by_o consequence_n it_o must_v have_v move_v in_o a_o instant_n but_o if_o a_o plane_n surface_n be_v say_v to_o touch_v a_o convexe_n surface_n it_o touch_v it_o only_o by_o a_o line_n as_o mathematican_n demonstrate_v or_o only_o by_o a_o point_n but_o to_o touch_v by_o a_o line_n

among_o body_n it_o be_v not_o to_o touch_v and_o so_o one_o such_o surface_n do_v not_o touch_v the_o other_o now_o for_o a_o plain_a surface_n to_o touch_v a_o concave_n every_o man_n see_v be_v

not_o to_o be_v a_o physical_a touch_v and_o if_o a_o convexe_n surface_n shall_v be_v say_v to_o touch_v a_o concave_n they_o must_v touch_v all_o at_o once_o as_o we_o say_v of_o plane_n surface_v and_o therefore_o the_o same_o impossibility_n will_v arise_v therein_o so_o that_o it_o be_v evident_a that_o no_o two_o surface_n move_v perpendicular_o towards_o one_o a_o other_o can_v come_v to_o

more_o of_o the_o nether_a surface_n it_o gain_v to_o touch_v more_o of_o it_o i_o say_v that_o neither_o in_o this_o case_n do_v they_o touch_v immediate_o one_o a_o other_o for_o as_o soon_o as_o

to_o look_v no_o further_o then_o among_o those_o body_n we_o converse_v withal_o of_o which_o have_v declare_v by_o what_o course_n and_o engine_n nature_n govern_v their_o common_a motion_n that_o be_v find_v even_o in_o the_o element_n and_o from_o thence_o be_v derive_v to_o all_o body_n compose_v of_o they_o we_o intend_v now_o to_o consider_v such_o motion_n as_o accompany_v diverse_a

for_o rarefaction_n we_o may_v remember_v how_o it_o proceed_v original_o from_o fire_n and_o depend_v of_o heat_n as_o be_v declare_v in_o the_o former_a chapter_n and_o wheresoever_o we_o find_v rarefaction_n we_o may_v be_v confident_a the_o body_n which_o suffer_v it_o be_v not_o without_o fire_n work_v upon_o it_o from_o hence_o we_o may_v gather_v that_o when_o the_o air_n imprison_v in_o a_o balloon_n or_o bladder_n swell_v against_o what_o contain_v it_o and_o stretch_v its_o case_n and_o seek_v to_o break_v out_o this_o effect_n must_v proceed_v from_o fire_n or_o heat_n though_o
