before_o i_o begin_v we_o must_v remark_n several_a thing_n the_o first_o be_v that_o it_o be_v a_o essential_a point_n to_o quench_v the_o coal_n of_o cork_n in_o aqua_fw-la aquavitae_fw-la that_o the_o visible_a ink_n may_v become_v black_a with_o it_o second_o that_o the_o blackness_n of_o this_o ink_n do_v proceed_v from_o the_o fuliginosity_n or_o sooty_a part_n of_o the_o coal_n of_o the_o

make_v the_o invisible_a ink_n be_v only_o a_o lead_n dissolve_v and_o hold_v up_o imperceptible_o in_o a_o acid_a liquor_n as_o i_o have_v say_v when_o i_o speak_v of_o this_o metal_n four_o that_o the_o first_o of_o these_o liquor_n be_v a_o mixture_n of_o the_o alkali_fw-la and_o igneous_a part_n of_o quicklime_n with_o the_o sulphureous_a substance_n of_o arsenic_n for_o the_o orpin_n be_v a_o sort_n of_o arsenic_n as_o i_o say_v before_o all_o this_o be_v grant_v as_o no_o body_n can_v reasonable_o think_v otherwise_o i_o now_o affirm_v that_o the_o reason_n why_o the_o visible_a ink_n

make_v disappear_z spot_n make_v by_o grease_n but_o it_o may_v be_v demand_v why_o after_o the_o dissolution_n the_o blackness_n do_v disappear_v i_o answer_v that_o the_o fuliginous_a part_n have_v be_v so_o divide_v and_o lock_v up_o in_o the_o sulphureous_a alkali_fw-la of_o the_o liquor_n that_o they_o be_v become_v invisible_a and_o we_o see_v every_o day_n that_o very_o exact_a solution_n

with_o the_o alkali_fw-la of_o the_o quicklime_n and_o to_o help_v the_o dissolution_n as_o for_o the_o invisible_a ink_n it_o be_v easy_a to_o apprehend_v how_o that_o appear_v black_a when_o the_o same_o liquor_n which_o serve_v to_o deface_v the_o other_o be_v use_v upon_o it_o for_o whereas_o the_o impregnation_n of_o saturn_n be_v only_o a_o lead_n suspend_v by_o the_o edge_n of_o the_o acid_a liquor_n this_o lead_n must_v needs_o revive_v and_o resume_v its_o black_a colour_n when_o that_o which_o hold_v it_o rarefy_v be_v entire_o destroy_v so_o the_o alkali_fw-la of_o quicklime_n

then_o that_o the_o visible_a ink_n do_v disappear_v by_o reason_n that_o the_o part_n which_o do_v render_v it_o black_a have_v be_v dissolve_v and_o the_o invisible_a ink_n do_v also_o appear_v

the_o matter_n whereas_o a_o great_a store_n of_o acid_n will_v quite_o fill_v the_o pore_n of_o this_o matter_n and_o hinder_v the_o motion_n of_o the_o natural_a salt_n for_o it_o be_v not_o enough_o that_o there_o be_v a_o great_a many_o acid_n to_o cause_v such_o a_o dissolution_n these_o acid_n must_v have_v room_n to_o move_v in_o and_o to_o make_v their_o jostle_v thus_o these_o effect_n do_v make_v nothing_o against_o what_o i_o have_v assert_v concern_v acid_n for_o a_o great_a quantity_n of_o they_o will_v always_o have_v more_o disposition_n and_o tendency_n to_o a_o dissolution_n but_o if_o this_o great_a quantity_n do_v coagulate_v divers_a thing_n it_o be_v only_o by_o accident_n and_o through_o the_o disposition_n of_o the_o matter_n into_o which_o the_o acid_a point_n have_v enter_v what_o i_o have_v here_o establish_v concern_v acid_n may_v serve_v very_o much_o to_o explicate_v the_o nature_n of_o fever_n and_o their_o principal_a symptom_n first_o of_o all_o every_o body_n must_v grant_v that_o when_o there_o be_v obstruction_n in_o our_o body_n the_o obstruct_a matter_n do_v ferment_n and_o sour_a as_o doughty_n wine_n and_o several_a other_o thing_n grow_v sour_a by_o be_v stale_a this_o matter_n by_o ferment_v send_v saline_a or_o acid_a vapour_n into_o the_o mass_n of_o blood_n which_o do_v cause_n divers_a alteration_n in_o it_o according_a to_o their_o quantity_n and_o quality_n for_o these_o acid_n be_v common_o mix_v with_o sulphur_n which_o be_v a_o kind_n of_o vehicle_n to_o the_o acid_n and_o be_v more_o or_o less_o corrupt_v according_a as_o the_o matter_n whence_o they_o be_v derive_v have_v sojourn_v more_o or_o less_o in_o the_o obstruct_a part_n now_o if_o these_o acid_a vapour_n be_v carry_v into_o the_o vessel_n but_o only_o in_o such_o a_o quantity_n as_o be_v fit_a to_o make_v a_o kind_n of_o leaven_n they_o will_v then_o rarify_v the_o blood_n too_o much_o and_o whereas_o they_o by_o consequence_n do_v increase_v its_o motion_n and_o heat_n they_o do_v cause_n that_o which_o we_o call_v a_o fever_n this_o fever_n must_v remain_v as_o long_o as_o the_o ferment_n continue_v in_o the_o blood_n and_o according_a as_o there_o come_v a_o new_a supply_n of_o matter_n in_o place_n of_o that_o which_o nature_n have_v throw_v off_o but_o if_o a_o great_a quantity_n of_o acid_n shall_v rise_v all_o of_o a_o sudden_a from_o out_o of_o the_o obstruction_n than_o there_o must_v needs_o happen_v a_o kind_n of_o coagulation_n for_o these_o acid_v thus_o abound_v and_o fix_v the_o grosser_n part_n of_o the_o blood_n do_v partly_o lose_v their_o motion_n and_o quiet_a the_o ebullition_n of_o the_o blood_n by_o fix_v its_o part_n it_o be_v this_o kind_n of_o congelation_n which_o cause_v those_o cold_a shivering_n which_o be_v feel_v before_o the_o hot_a fit_n begin_v for_o as_o the_o heat_n be_v derive_v from_o the_o motion_n of_o the_o spirit_n the_o cold_a be_v produce_v from_o the_o cessation_n of_o their_o motion_n the_o cold_a fit_n continue_v until_o the_o spirit_n have_v by_o their_o activity_n rarefy_v this_o congelation_n for_o the_o spirit_n be_v continual_o supply_v with_o additional_a force_n do_v make_v violent_a assault_n until_o they_o have_v make_v their_o way_n free_a the_o coagulum_fw-la be_v dissolve_v the_o blood_n shall_v seem_v to_o circulate_v as_o it_o do_v before_o but_o because_o the_o matter_n of_o the_o coagulum_fw-la be_v convert_v into_o a_o leaven_n this_o leaven_n make_v the_o blood_n to_o boil_v and_o so_o cause_v a_o fever_n this_o fever_n continue_v until_o the_o blood_n be_v free_v from_o all_o this_o ferment_n either_o by_o transpiration_n or_o by_o urine_n now_o to_o conceive_v how_o this_o coagulum_fw-la may_v be_v convert_v into_o a_o leaven_n we_o must_v consider_v that_o the_o spirit_n of_o the_o blood_n have_v lose_v most_o of_o their_o acidity_n in_o dissolve_v this_o coagulum_fw-la and_o that_o there_o remain_v but_o only_a acidity_n enough_o to_o produce_v a_o fermentation_n nevertheless_o you_o must_v not_o think_v i_o mean_v by_o this_o congelation_n now_o speak_v of_o a_o coagulum_fw-la altogether_o like_a to_o that_o in_o milk_n or_o to_o that_o which_o happen_v when_o a_o acid_a liquor_n be_v syringe_v into_o the_o vein_n of_o a_o animal_n for_o these_o congelation_n be_v too_o strong_a and_o there_o will_v then_o happen_v the_o same_o thing_n or_o very_o near_o the_o same_o as_o do_v to_o the_o animal_n who_o soon_o afterward_o fall_v into_o convulsion_n and_o die_v because_o the_o course_n of_o the_o spirit_n and_o blood_n will_v be_v entire_o stop_v and_o they_o will_v never_o be_v able_a to_o break_v through_o so_o great_a a_o obstacle_n but_o i_o do_v understand_v here_o that_o the_o blood_n be_v make_v thick_a than_o it_o be_v and_o have_v not_o so_o free_a a_o motion_n as_o it_o have_v before_o which_o be_v enough_o to_o cause_v such_o cold_a fit_n now_o it_o remain_v for_o i_o to_o explicate_v how_o it_o come_v to_o pass_v that_o fever_n have_v their_o return_n regular_o by_o fit_n the_o matter_n that_o make_v the_o obstruction_n which_o i_o have_v lay_v down_o for_o the_o fundamental_a cause_n of_o fever_n begin_v not_o to_o send_v forth_o its_o vapour_n nor_o to_o disperse_v its_o acid_a salt_n into_o the_o blood_n in_o order_n to_o cause_v a_o fever_n until_o it_o have_v get_v together_o a_o certain_a quantity_n in_o the_o obstruct_a vessel_n and_o then_o it_o be_v probable_a that_o there_o be_v a_o new_a discharge_n of_o the_o matter_n this_o discharge_n or_o eruption_n of_o feverish_a matter_n must_v happen_v at_o set_a time_n so_o long_o as_o the_o obstruction_n last_v because_o the_o humour_n which_o circulate_v to_o the_o obstruct_a part_n and_o there_o stop_v be_v always_o in_o a_o equal_a quickness_n and_o a_o equal_a quantity_n now_o because_o in_o a_o tertian_n the_o vessel_n wherein_o the_o obstruction_n happen_v do_v acquire_v in_o two_o day_n a_o sufficient_a repletion_n of_o matter_n to_o produce_v the_o eruption_n and_o fermentation_n i_o have_v speak_v of_o the_o fit_n do_v come_v to_o operate_v every_o second_o day_n but_o because_o in_o a_o quartan_a the_o humour_n be_v more_o tenacious_a and_o heavy_a and_o flow_v with_o less_o expedition_n the_o fermentation_n and_o eruption_n must_v needs_o be_v slow_a and_o consequent_o the_o fit_n more_o distant_a the_o one_o from_o the_o other_o the_o quotidian_n ague_n be_v cause_v by_o a_o saline_n pituita_fw-la which_o be_v natural_o fluid_a enough_o to_o make_v the_o matter_n ferment_n in_o less_o time_n wherefore_o it_o be_v that_o the_o fit_n do_v return_v every_o day_n we_o may_v reason_v concern_v the_o other_o kind_n of_o fever_n upon_o the_o same_o principle_n and_o explicate_v all_o the_o accident_n that_o happen_v but_o i_o have_v no_o design_n to_o enlarge_v myself_o further_o upon_o this_o subject_n i_o shall_v think_v it_o will_v be_v too_o great_a a_o digression_n and_o a_o book_n shall_v rather_o be_v make_v on_o purpose_n to_o express_v all_o the_o circumstance_n which_o may_v be_v deduce_v from_o it_o
