bring_v no_o detriment_n at_o all_o to_o the_o substance_n of_o it_o in_o this_o i_o speak_v only_o of_o a_o ordinary_a fire_n for_o i_o doubt_v not_o but_o such_o a_o one_o it_o may_v be_v it_o as_o

not_o have_v part_n but_o vacuum_n be_v nothing_o because_o as_o the_o adversary_n conceive_v it_o vacuum_n be_v the_o want_n of_o a_o corporeal_a substance_n in_o a_o enclose_v body_n within_o who_o

this_o i_o conceive_v to_o be_v absolute_o unavoidable_a substance_n for_o these_o reason_n therefore_o i_o must_v entreat_v my_o reader_n favour_n that_o he_o will_v allow_v i_o to_o touch_v upon_o

and_o therefore_o give_v for_o definition_n of_o the_o nature_n of_o it_o that_o it_o gather_v thing_n of_o diverse_a nature_n and_o experience_n show_v we_o in_o freeze_a and_o all_o great_a

in_o this_o operation_n hot_a we_o shall_v find_v that_o the_o less_o dense_a one_o be_v more_o capable_a of_o be_v apply_v round_o about_o the_o body_n it_o shall_v besiege_v and_o therefore_o will_v

can_v not_o so_o easy_o bend_v and_o ply_v they_o to_o work_v this_o effect_n and_o therefore_o a_o body_n that_o be_v moderate_o dense_a be_v cold_a than_o a_o other_o that_o be_v so_o in_o excess_n see_v that_o cold_a be_v a_o active_a or_o work_a power_n and_o that_o which_o be_v less_o dense_a do_v excel_v in_o work_v on_o the_o contrary_a side_n rare_a body_n be_v hot_a because_o their_o subtle_a part_n environ_v a_o compound_a body_n will_v sink_v into_o the_o pore_n of_o it_o and_o to_o their_o power_n separate_v its_o part_n it_o follow_v that_o those_o wherein_o the_o gravity_n

they_o meet_v with_o than_o these_o do_v so_o that_o out_o of_o this_o discourse_n we_o gather_v that_o of_o such_o body_n that_o differ_v precise_o by_o the_o proportion_n of_o rarity_n and_o

dense_a body_n be_v moist_a though_o not_o in_o such_o excess_n as_o rare_a one_o that_o be_v so_o but_o be_v cold_a of_o any_o and_o last_o that_o extreme_a dense_a body_n be_v less_o cold_a than_o

a_o facility_n to_o yield_v unto_o division_n be_v nothing_o else_o but_o a_o plyablenesse_n in_o the_o thing_n that_o be_v to_o be_v divide_v whereby_o it_o easy_o receive_v the_o figure_n which_o the_o thing_n that_o divide_v it_o do_v cast_v it_o into_o now_o this_o plyablenesse_n belong_v more_o to_o rare_a then_o to_o dense_a thing_n and_o according_o we_o see_v fire_n bend_v more_o easy_o by_o the_o concameration_n of_o a_o oven_n than_o a_o stone_n can_v be_v reduce_v into_o due_a figure_n by_o hew_v and_o therefore_o since_o dryness_n be_v a_o quality_n that_o make_v those_o body_n wherein_o it_o reign_v to_o conserve_v themselves_o in_o their_o own_o figure_n and_o limit_n and_o to_o resist_v the_o receive_n of_o any_o from_o a_o other_o body_n it_o be_v manifest_a that_o

and_o last_o that_o the_o conjunction_n of_o gravity_n with_o these_o two_o breed_v two_o other_o sort_n of_o combination_n each_o of_o which_o be_v also_o twofold_a the_o first_o sort_n concern_v

by_o this_o we_o see_v that_o the_o notion_n of_o divider_n and_o divisible_a do_v immediate_o follow_v rare_a and_o dense_a body_n and_o do_v so_o much_o the_o more_o proper_o agree_v unto_o they_o as_o they_o exceed_v in_o the_o quality_n of_o rarity_n and_o density_n likewise_o we_o be_v to_o observe_v in_o our_o case_n that_o the_o dense_n or_o divide_v body_n must_v necessary_o cut_v and_o

the_o solution_n of_o the_o other_o part_n of_o the_o same_o objection_n which_o be_v of_o many_o light_n join_v in_o the_o same_o place_n and_o the_o same_o be_v likewise_o concern_v the_o image_n

of_o all_o know_a body_n be_v of_o its_o own_o nature_n by_o reason_n of_o the_o divisibility_n that_o follow_v rarity_n divisible_a into_o lesser_a part_n then_o any_o other_o and_o particular_o then_o flame_n which_o be_v mix_v with_o smoke_n and_o other_o corpulency_n fall_v very_o short_a of_o light_n and_o this_o to_o the_o proportion_n in_o which_o it_o be_v more_o rare_a than_o the_o body_n it_o be_v compare_v unto_o now_o a_o great_a mathematician_n have_v devise_v how_o to_o measure_v the_o rarefaction_n of_o gunnepowder_n into_o flame_n snell_n find_v the_o diameter_n to_o

wherefore_o by_o the_o immediate_o proceed_v consequence_n we_o find_v that_o 125000_o part_n of_o flame_n may_v be_v couch_v in_o the_o room_n of_o one_o lest_o part_n of_o gunnepowder_n and_o

and_o be_v contain_v many_o time_n in_o the_o bigness_n of_o the_o sight_n of_o a_o man_n eye_n out_o of_o which_o we_o may_v gather_v what_o a_o infinity_n of_o object_n may_v seem_v unto_o we_o to_o

from_o the_o flame_n it_o be_v obvious_a enough_o to_o conceive_v how_o in_o the_o space_n where_o the_o air_n be_v there_o be_v capacity_n for_o the_o ray_n of_o many_o candle_n which_o be_v well_o

have_v great_a store_n of_o fire_n in_o itself_o while_o it_o be_v boil_v as_o we_o see_v by_o its_o be_v red_a hot_a and_o hence_o it_o be_v that_o the_o workman_n be_v force_v to_o let_v it_o cool_v

that_o be_v raise_v against_o our_o opinion_n by_o so_o incompetent_a a_o judge_n will_v fall_v flat_a to_o the_o ground_n first_o then_o let_v i_o put_v the_o reader_n in_o mind_n how_o if_o ever_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

he_o will_v likewise_o plain_o see_v that_o if_o there_o be_v any_o other_o little_a dense_a body_n float_v in_o the_o air_n they_o must_v likewise_o mount_v a_o little_a through_o this_o swell_a

of_o impulse_n or_o stroke_n that_o the_o air_n give_v those_o denser_n body_n but_o by_o way_n of_o contain_v they_o in_o it_o and_o carry_v they_o with_o it_o â—o_z that_o it_o give_v they_o no_o more_o celerity_n then_o to_o make_v they_o go_v with_o itself_o and_o as_o part_n of_o itself_o then_o let_v he_o consider_v that_o light_n or_o fire_n by_o much_o beat_n upon_o the_o earth_n divide_v some_o little_a part_n of_o it_o from_o other_o whereof_o if_o any_o do_v become_v so_o small_a and_o tractable_a as_o not_o to_o exceed_v the_o strength_n which_o the_o ray_n have_v to_o

of_o density_n as_o will_v arise_v out_o of_o the_o composition_n and_o knead_n together_o the_o several_a density_n of_o those_o two_o part_n now_o then_o when_o these_o little_a compound_a body_n of_o light_n and_o earth_n be_v carry_v up_o to_o a_o determinate_a height_n the_o part_n of_o fire_n or_o light_n do_v by_o little_a and_o little_o break_v away_o from_o they_o and_o thereby_o the_o

to_o increase_v their_o bulk_n and_o to_o become_v more_o powerful_a in_o density_n not_o only_o by_o the_o loss_n of_o their_o fire_n but_o also_o by_o the_o increase_n of_o their_o quantity_n and_o so_o it_o be_v evident_a that_o they_o be_v denser_n come_v down_o then_o go_v up_o last_o let_v he_o consider_v that_o those_o atom_n which_o go_v up_o first_o and_o be_v part_v from_o their_o

to_o where_o they_o be_v and_o do_v go_v beyond_o they_o by_o reason_n of_o their_o great_a levity_n and_o as_o the_o latter_a atom_n come_v up_o with_o a_o violence_n and_o a_o great_a celerity_n so_o must_v the_o first_o go_v down_o with_o a_o smart_a impulse_n and_o by_o consequence_n be_v more_o dense_a than_o the_o air_n in_o which_o they_o be_v carry_v must_v of_o necessity_n cut_v

show_v we_o that_o the_o less_o the_o atom_n shall_v penetrate_v into_o a_o move_a body_n by_o reason_n of_o the_o extreme_a density_n of_o it_o the_o more_o efficacious_o they_o will_v work_v and_o

connexion_n of_o its_o part_n it_o be_v evident_a that_o the_o force_n of_o motion_n if_o it_o be_v exercise_v upon_o they_o must_v of_o necessity_n separate_v they_o as_o we_o see_v in_o break_v 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 how_o they_o work_v so_o that_o it_o be_v not_o difficult_a to_o find_v the_o reason_n why_o some_o hard_a body_n break_v easy_o and_o other_o with_o much_o ado_n the_o first_o of_o which_o be_v call_v brittle_a the_o other_o tough_a for_o if_o you_o mark_v it_o all_o break_n require_v that_o bend_a hold_n precede_v which_o on_o the_o one_o side_n compress_v the_o part_n of_o the_o bend_a body_n and_o condense_v they_o into_o a_o lesser_a room_n than_o they_o possess_v before_o and_o on_o the_o otherside_n stretch_v they_o out_o and_o make_v they_o take_v up_o more_o place_n this_o require_v some_o fluid_n or_o movable_a substance_n to_o be_v within_o the_o body_n else_o it_o can_v not_o be_v do_v for_o without_o such_o help_n the_o part_n can_v not_o remove_v therefore_o such_o hard_a body_n as_o have_v most_o fluid_n part_n in_o they_o be_v most_o flexible_a that_o be_v be_v tough_a and_o those_o which_o have_v few_o though_o they_o become_v thereby_o hard_a to_o have_v impression_n make_v upon_o they_o yet_o if_o the_o force_n be_v able_a to_o do_v it_o they_o rather_o yield_v to_o break_v then_o to_o bend_v and_o thence_o be_v call_v brittle_a out_o of_o this_o 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 more_o than_o one_o will_v expect_v if_o it_o be_v wrought_v upon_o with_o time_n and_o dexterity_n for_o there_o be_v none_o but_o contain_v in_o it_o some_o liquid_a part_n more_o or_o less_o even_o glass_n and_o brick_n upon_o which_o occasion_n i_o remember_v how_o once_o in_o a_o great_a storm_n of_o wind_n i_o see_v the_o high_a slender_a brick_n chimney_n of_o the_o king_n house_n at_o st_n james_n one_o winter_n when_o the_o ourt_n lie_v there_o bend_v from_o the_o wind_n like_o bow_n and_o shark_n exceed_o and_o totter_v and_o at_o other_o time_n i_o have_v see_v some_o very_a high_a and_o pointy_a spire_n steeple_n do_v the_o like_a and_o i_o have_v be_v assure_v the_o like_a of_o the_o whole_a pile_n of_o a_o high_a castle_n stand_v in_o a_o gullet_n in_o the_o course_n of_o the_o wind_n namely_o the_o castle_n of_o wardour_n by_o those_o who_o have_v often_o see_v it_o shake_v notable_o in_o a_o fierce_a wind_n the_o reason_n of_o all_o which_o may_v be_v deduce_v out_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 bend_v still_o more_o and_o more_o as_o their_o absence_n glu_v it_o leave_v but_o if_o the_o motion_n that_o be_v wrought_v in_o it_o be_v too_o quick_a then_o the_o spirit_n not_o have_v time_n 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 it_o stick_v together_o and_o that_o this_o shortenesse_n may_v be_v in_o so_o high_a a_o degree_n as_o nothing_o can_v come_v between_o the_o part_n they_o glue_v together_o to_o divide_v they_o 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 whatsoever_o degree_n of_o shortenesse_n they_o be_v must_v necessary_o have_v still_o some_o latitude_n it_o can_v not_o be_v doubt_v but_o there_o may_v be_v some_o force_n assign_v great_a than_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

we_o may_v remember_v how_o in_o the_o close_a of_o the_o four_o we_o remit_v a_o question_n concern_v the_o existence_n of_o the_o element_n that_o be_v whether_o in_o any_o place_n of_o the_o
