for_o several_a day_n together_o without_o the_o least_o drink_n though_o in_o the_o mean_a time_n he_o sweat_v moderate_o and_o easy_o enough_o his_o urine_n be_v agreeable_a to_o his_o

the_o more_o their_o fluidity_n be_v increase_v body_n a_o fluid_n may_v be_v obtain_v from_o a_o consistent_a body_n and_o here_o it_o may_v not_o be_v unseasonable_a to_o inquire_v how_o it_o come_v to_o pass_v that_o a_o transparent_a liquor_n shall_v be_v draw_v from_o such_o brittle_a body_n as_o common_a salt_n i_o know_v it_o be_v usual_o allege_v that_o the_o fire_n only_o separate_v the_o

it_o be_v rather_o probable_a that_o the_o fire_n only_o divide_v their_o part_n and_o put_v they_o into_o a_o violent_a agitation_n by_o which_o they_o be_v raise_v in_o the_o form_n of_o vapour_n

and_o so_o preserve_v that_o body_n in_o the_o form_n of_o a_o fluid_a the_o motion_n of_o the_o air_n or_o of_o some_o interpose_a body_n concur_v to_o preserve_v the_o part_n of_o that_o in_o

since_o several_a body_n will_v be_v freeze_v with_o one_o degree_n of_o cold_a with_o which_o other_o will_v not_o and_o though_o the_o watery_a part_n of_o wine_n in_o some_o country_n will_v

the_o air_n yet_o it_o be_v never_o so_o far_o condense_v as_o to_o become_v ice_n because_o the_o perpetual_a motion_n concur_v with_o the_o minuteness_n and_o shape_n of_o its_o part_n they_o be_v always_o in_o a_o agitation_n requisite_a to_o keep_v it_o in_o that_o form_n and_o it_o be_v not_o improbable_a but_o that_o the_o part_n of_o salt_n be_v very_a minute_n since_o from_o experiment_n before_o mention_v it_o appear_v that_o spirit_n of_o salt_n and_o urine_n will_v unite_v into_o a_o salarmoniack_a and_o it_o be_v further_o confirm_v since_o common-salt_n mix_v with_o aqua_fw-la

may_v be_v a_o question_n whether_o the_o fluidity_n of_o these_o body_n may_v not_o in_o part_n proceed_v from_o the_o action_n of_o the_o fire_n work_v upon_o some_o part_n of_o the_o concrete_a

but_o i_o must_v confess_v there_o be_v two_o difficulty_n answer_v objection_n answer_v which_o occur_v to_o what_o i_o have_v be_v offer_v as_o first_o that_o it_o be_v hard_o to_o imagine_v how_o

internal_a part_n of_o a_o needle_n to_o the_o superficies_n as_o our_o hypothesis_n require_v but_o to_o the_o first_o i_o answer_v that_o those_o external_n part_n be_v not_o the_o sole_a cause_n of_o these_o motion_n but_o only_a assistant_n to_o the_o principal_a which_o be_v evident_a from_o what_o have_v late_o be_v note_v concern_v the_o connate_a disposition_n to_o motion_n attribute_v to_o matter_n according_a to_o the_o epicurean_a and_o cartesian_a philosophy_n and_o by_o the_o effect_n of_o a_o loadstone_n upon_o the_o needle_n we_o may_v be_v teach_v to_o guess_v what_o
dispose_v to_o influence_n the_o superficial_a region_n of_o the_o earth_n than_o the_o hot_a one_o which_o lie_v under_o it_o appear_v from_o reason_n itself_o and_o may_v be_v further_o confirm_v

subject_a to_o the_o influence_n of_o external_n cold_n and_o it_o be_v observe_v not_o only_o in_o england_n but_o also_o in_o russia_n that_o if_o wine_n or_o beer_n be_v keep_v in_o a_o cellar_n

that_o the_o warmth_n of_o those_o vault_n do_v not_o only_o depend_v on_o the_o exclusion_n of_o external_n air_n but_o also_o on_o the_o steam_n of_o those_o ferment_a liquor_n together_o with_o

why_o that_o region_n shall_v have_v its_o part_n less_o agitate_a than_o those_o about_o it_o be_v plain_a because_o it_o lie_v remote_a both_o from_o the_o influence_n of_o external_n as_o well_o

have_v say_v i_o shall_v add_v that_o i_o have_v not_o only_o see_v a_o fly_n in_o shape_n and_o size_n much_o like_o a_o grass-hopper_n enclose_v in_o solid_a amber_n but_o various_o and_o curious_o

and_o black_a or_o abound_v with_o black_a or_o red_a sand_n and_o in_o some_o the_o gem_n have_v be_v observe_v to_o be_v black_a or_o yellow_a but_o though_o this_o author_n have_v say_v thus_o much_o which_o countenance_n our_o hypothesis_n yet_o i_o must_v not_o omit_v to_o advertise_v that_o though_o he_o assert_n diamond_n to_o be_v not_o only_o the_o hard_a but_o heavy_a of_o stone_n i_o must_v yet_o say_v that_o they_o be_v not_o the_o heavy_a as_o may_v be_v hydrostatical_o discover_v but_o perhaps_o against_o what_o we_o have_v say_v it_o may_v be_v urge_v first_o that_o the_o figure_n of_o these_o crystal_n be_v so_o curious_a that_o a_o plastic_a or_o seminal_a power_n seem_v requisite_a to_o the_o form_n of_o they_o which_o be_v it_o requisite_a it_o may_v be_v answer_v that_o that_o plastic_a power_n may_v be_v lodge_v in_o fluid_a as_o well_o as_o solid_a substance_n since_o the_o solid_a part_n of_o animal_n body_n as_o well_o as_o plant_n be_v form_v of_o liquid_a substance_n but_o that_o the_o figure_n of_o these_o crystal_n may_v be_v owe_v to_o a_o apt_a convension_n and_o coalition_n of_o fluid_a particle_n may_v be_v argue_v hence_o viz._n since_o common_a salt_n by_o the_o help_n of_o oil_n of_o sulphur_n or_o of_o vitriol_n and_o water_n will_v shoot_v into_o crystal_n with_o point_n like_o diamond_n and_o not_o unlike_o native_a crystal_n in_o shape_n and_o transparency_n but_o if_o the_o quality_n or_o proportion_n of_o the_o oil_n of_o vitriol_n be_v vary_a they_o will_v shoot_v into_o crystal_n sometime_o of_o one_o shape_n and_o sometime_o of_o another_o for_o the_o most_o part_n fively_z figure_v and_o to_o show_v that_o the_o regular_a figure_n of_o sea-salt_n contribute_v not_o to_o such_o figuration_n i_o shall_v add_v that_o have_v dissolve_v some_o stony_a stiriae_fw-la find_v in_o cave_n or_o grotto_n in_o spirit_n of_o verdigrease_n and_o evaporate_v the_o clear_a solution_n in_o a_o digestive_a furnace_n after_o the_o ordinary_a manner_n it_o yield_v rather_o a_o coagulate_v mass_n than_o any_o thing_n like_o crystal_n whence_o it_o appear_v that_o a_o concourse_n of_o circumstance_n may_v be_v
