the_o three_o chapter_n of_o rarity_n and_o density_n i_o intend_v in_o this_o chapter_n to_o look_v as_o far_o as_o i_o can_v into_o the_o nature_n and_o cause_n of_o the_o two_o first_o difference_n

of_o they_o among_o themselves_o will_v be_v a_o great_a and_o important_a step_n in_o the_o journey_n we_o be_v go_v but_o the_o scarcity_n of_o our_o language_n be_v such_o in_o subiet_n remove_v

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 and_o solidity_n one_o than_o a_o other_o which_o term_n or_o any_o i_o can_v find_v in_o english_a do_v not_o signify_v full_o those_o affection_n of_o quantity_n that_o i_o intend_v here_o to_o

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

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

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

cut_a file_v draw_v a_o sunder_o and_o the_o like_a all_o these_o motion_n because_o they_o be_v do_v by_o gross_a body_n do_v require_v great_a part_n to_o work_v upon_o and_o be_v easy_o discern_v

we_o may_v infer_v that_o some_o body_n may_v be_v so_o sudden_o bend_v as_o that_o thereby_o they_o break_v asunder_o whereas_o if_o they_o be_v leisurely_o and_o gentle_o deal_v withal_o they_o will_v take_v what_o ply_v one_o desire_v and_o likewise_o that_o there_o be_v no_o body_n be_v it_o never_o so_o brittle_a and_o hard_a but_o that_o it_o will_v bend_v a_o little_a and_o indeed_o

of_o what_o we_o have_v say_v above_o for_o see_v that_o the_o bend_n of_o a_o body_n make_v the_o spirit_n or_o humour_n that_o be_v within_o it_o to_o sally_v forth_o it_o be_v clear_a that_o if_o the_o violence_n which_o force_v it_o be_v not_o so_o sudden_a nor_o the_o motion_n it_o receive_v be_v not_o so_o quick_a but_o that_o the_o moisture_n may_v oose_v gentle_o out_o the_o body_n will_v

allow_v they_o to_o go_v leisurely_o and_o gentle_o out_o do_v force_n their_o prison_n and_o break_v out_o with_o a_o violence_n and_o so_o the_o body_n be_v snap_v into_o two_o here_o peradventure_o some_o remember_v what_o we_o have_v say_v in_o a_o other_o place_n body_n namely_o that_o it_o be_v the_o shortenesse_n and_o littleness_n of_o the_o humid_a part_n in_o a_o body_n which_o make_v

may_v ask_v how_o a_o very_a dense_a body_n of_o such_o a_o strain_n can_v be_v break_v or_o divide_v but_o the_o difficulty_n be_v not_o great_a for_o see_v that_o the_o humid_a part_n in_o

their_o resistance_n can_v be_v all_o the_o question_n be_v how_o to_o apply_v it_o to_o work_v its_o effect_n upon_o so_o close_a a_o compact_a body_n in_o which_o peradventure_o the_o continuity_n of_o the_o humid_a part_n that_o bind_v the_o other_o together_o may_v be_v so_o small_a as_o no_o other_o body_n whatsoever_o no_o not_o fire_n can_v go_v between_o they_o in_o such_o sort_n as_o to_o separate_v part_n from_o part_n att_n the_o worst_a it_o can_v not_o be_v doubt_v but_o that_o the_o force_n may_v be_v so_o apply_v at_o the_o outside_n of_o that_o body_n as_o to_o make_v the_o part_n of_o it_o press_v and_o fight_v one_o against_o a_o other_o and_o att_z the_o length_n by_o multiplication_n of_o the_o force_n constrain_v it_o to_o yield_v and_o suffer_v division_n and_o this_o i_o conceive_v to_o be_v the_o condition_n of_o gold_n and_o of_o some_o precious_a stone_n in_o which_o the_o element_n be_v unite_v by_o such_o little_a part_n as_o nothing_o but_o a_o

but_o this_o way_n of_o dissolve_v such_o body_n more_o proper_o belong_v to_o the_o next_o way_n of_o work_v upon_o they_o by_o fire_n yet_o the_o same_o be_v do_v when_o some_o exterior_a violence_n

phlegme_n and_o earth_n now_o these_o be_v not_o pure_a and_o simple_a part_n of_o the_o dissolve_a body_n but_o new_o compound_v body_n make_v of_o the_o first_o by_o the_o operation_n of_o heat_n

of_o the_o body_n and_o lie_v as_o it_o be_v loose_o scatter_v in_o it_o the_o fire_n will_v carry_v they_o away_o with_o it_o thâ—se_o will_v be_v the_o first_o that_o be_v separate_v from_o the_o

let_v we_o conceive_v that_o all_o the_o quantity_n of_o the_o world_n be_v in_o one_o uniform_a substance_n than_o the_o whole_a universe_n will_v be_v in_o one_o and_o the_o same_o degree_n of_o

in_o they_o when_o heat_n enter_v into_o they_o and_o work_v upon_o they_o and_o thus_o he_o may_v confident_o resolve_v himself_o that_o the_o first_o motion_n which_o light_n cause_v in_o the_o

the_o iron_n must_v sink_v in_o the_o water_n and_o the_o cork_n will_v swim_v upon_o it_o and_o this_o same_o be_v the_o cause_n why_o if_o a_o piece_n of_o cork_n be_v hold_v by_o force_n at_o the_o

have_v more_o force_n upon_o the_o water_n then_o upon_o the_o cork_n they_o make_v the_o water_n sink_v and_o slide_v under_o it_o first_o a_o little_a thin_a plate_n of_o water_n and_o then_o a_o

than_o if_o a_o dense_a body_n do_v fall_n into_o such_o a_o current_n where_o these_o different_a motion_n give_v their_o several_a impulse_n it_o will_v be_v carry_v in_o such_o sort_n as_o we_o

the_o thing_n in_o which_o it_o be_v wrought_v and_o not_o from_o any_o outward_a cause_n we_o may_v conclude_v it_o have_v its_o origine_fw-la from_o a_o heat_n that_o be_v within_o the_o thing_n

bend_v both_o every_o man_n conceit_n be_v and_o the_o nature_n of_o the_o thing_n make_v we_o believe_v that_o the_o force_n which_o bring_v the_o tree_n back_o again_o to_o its_o figure_n come_v from_o the_o inner_a side_n that_o be_v bend_v which_o be_v compress_v together_o as_o be_v shrink_v into_o a_o circular_a figure_n from_o a_o straight_a one_o for_o when_o solid_a body_n that_o be_v

be_v plain_a but_o the_o concave_n will_v be_v short_a and_o therefore_o we_o may_v conceive_v that_o the_o spirit_n which_o be_v in_o the_o contract_a part_n be_v there_o squeeze_v into_o less_o

it_o be_v clear_a that_o freedom_n of_o passage_n can_v happen_v unto_o light_n only_o there_o where_o there_o be_v a_o extreme_a great_a multitude_n of_o pore_n and_o part_n in_o a_o very_a little_a
