this_o kind_n that_o come_v to_o my_o knowledge_n i_o shall_v add_v only_o by_o and_o by_o the_o product_n of_o a_o more_o recent_a trial_n 2._o as_o far_o as_o i_o have_v hitherto_o observe_v those_o ferruginous_a water_n that_o be_v not_o heavy_a than_o common_a water_n and_o in_o most_o drinker_n prove_v but_o diuretic_n afford_v but_o very_o little_a caput_n mortuum_n or_o dry_a substance_n upon_o the_o total_a evaporation_n of_o the_o liquor_n whereas_o mineral_n water_n that_o be_v purge_v and_o manifest_o more_o ponderous_a in_o specie_fw-la then_o common_a water_n leave_v upon_o evaporation_n a_o considerable_a quantity_n of_o residence_n tho'_o some_o far_o less_o than_o other_o 3._o at_o once_o to_o explain_v and_o partly_o prove_v what_o i_o have_v be_v say_v i_o shall_v here_o recite_v that_o from_o a_o pound_n of_o barnet_n water_n which_o be_v know_v to_o be_v purgative_a slow_o evaporate_v we_o obtain_v a_o dram_n of_o white_a powder_n but_o from_o the_o like_a quantity_n of_o tunbridge_n water_n we_o obtain_v but_o about_o one_o grain_n of_o caput_n mortuum_n and_o if_o i_o misremember_v not_o we_o have_v but_o about_o a_o grain_n and_o a_o half_a from_o 25._o ounce_n of_o the_o german_a spa_n water_n 4._o it_o may_v seem_v scarce_o credible_a to_o many_o that_o so_o small_a a_o quantity_n of_o matter_n of_o which_o perhaps_o not_o one_o half_a be_v saline_n or_o metalline_a the_o rest_n be_v teresstrial_a shall_v impart_v a_o manifest_a virtue_n to_o so_o great_a a_o proportion_n of_o water_n but_o this_o difficulty_n do_v not_o much_o trouble_v i_o who_o have_v purposely_o make_v divers_a experiment_n to_o discover_v how_o small_a a_o proportion_n of_o mineral_n matter_n may_v suffice_v when_o dissolve_v to_o impregnate_n common_a water_n i_o remember_v i_o take_v one_o grain_n of_o iron_n stone_n casual_o find_v near_o the_o spring_n at_o islington_n from_o which_o mineral_n it_o be_v probable_a those_o water_n derive_v their_o virtue_n this_o be_v open_v by_o the_o fire_n and_o dissolve_v as_o far_o as_o it_o will_v be_v in_o a_o little_a spirit_n of_o salt_n we_o let_v fall_v a_o drop_n or_o two_o of_o the_o yellowish_a solution_n into_o a_o great_a proportion_n of_o infusion_n of_o gall_n to_o which_o it_o present_o give_v a_o deep_a colour_n than_o tunbridge_n water_n or_o even_o the_o german_a spa_n water_n be_v wont_a to_o give_v here_o at_o london_n with_o the_o powder_n of_o gall_n so_o that_o we_o guess_v that_o if_o we_o have_v then_o have_v at_o hand_n a_o competent_a quantity_n of_o the_o infusion_n the_o remain_a part_n of_o the_o martial_a solution_n will_v have_v be_v able_a to_o colour_v ten_o time_n a_o great_a quantity_n of_o the_o infusion_n than_o our_o trial_n be_v make_v upon_o this_o will_v be_v easy_o believe_v by_o he_o that_o shall_v consider_v a_o experiment_n we_o afterward_o make_v to_o the_o same_o purpose_n which_o be_v this_o we_o dissolve_v a_o half_a grain_n of_o a_o good_a marcasite_n take_v up_o not_o far_o from_o london_n in_o a_o small_a quantity_n of_o spirit_n of_o niter_n which_o for_o a_o certain_a reason_n i_o make_v choice_n of_o tho'_o other_o acid_n menstruum_n as_o aquafortis_n and_o spirit_n of_o salt_n will_v have_v dissolve_v the_o mineral_n this_o small_a solution_n we_o put_v into_o a_o pound_n of_o pretty_a high_a tincture_n of_o gall_n make_v by_o infuse_v they_o in_o common_a water_n and_o find_v as_o we_o expect_v that_o this_o mixture_n grow_v very_o dark_a we_o fill_v a_o vial_n with_o it_o and_o empty_v that_o vial_n into_o a_o large_a glass_n we_o fill_v the_o same_o vial_n three_o time_n with_o common_a water_n to_o dilute_v it_o notwithstanding_o which_o this_o new_a mixture_n be_v put_v into_o one_o of_o our_o usual_a glass_n appear_v of_o a_o colour_n much_o deep_a than_o that_o which_o the_o water_n of_o tunbridge_n or_o the_o german_a spa_n have_v former_o give_v with_o the_o powder_n of_o gall_n so_o that_o probable_o if_o another_o vial_n of_o common_a water_n have_v be_v add_v it_o will_v yet_o have_v afford_v a_o purple_a colour_n if_o not_o a_o deep_a so_o that_o one_o part_n of_o dissolve_v marcasite_n communicate_v a_o tincture_n to_o 61440_o sixty_o one_o thousand_o four_o hundred_o and_o forty_o part_n of_o infusion_n of_o gall_n and_o that_o which_o make_v this_o experiment_n more_o considerable_a be_v that_o this_o small_a quantity_n of_o marcasite_n be_v not_o itself_o all_o martial_a or_o metalline_a for_o from_o our_o english_a marcasite_n as_o well_o as_o other_o i_o have_v obtain_v a_o pretty_a quantity_n of_o sulphur_n like_o common_a sulphur_n beside_o that_o they_o afford_v a_o not_o despicable_a quantity_n of_o terrestrial_a substance_n about_o who_o nature_n i_o have_v not_o yet_o satisfy_v myself_o 5._o i_o shall_v now_o add_v this_o reflection_n that_o since_o the_o marcasite_n impregnate_v so_o much_o water_n with_o its_o corporeal_a part_n if_o i_o may_v so_o call_v they_o obtain_v by_o bare_a dissolution_n it_o seem_v high_o probable_a that_o the_o same_o quantity_n of_o liquor_n may_v be_v impregnate_v by_o a_o far_o less_o quantity_n of_o mineral_n matter_n attenuate_v into_o a_o kind_n of_o spirituous_a slate_n by_o be_v raise_v in_o the_o form_n of_o fume_n or_o exhalation_n and_o that_o imperfect_a or_o embryonated_a iron_n may_v be_v so_o will_v scarce_o be_v deny_v by_o they_o that_o consider_v the_o way_n that_o i_o have_v in_o another_o paper_n deliver_v to_o make_v iron_n manifest_o emit_v copious_a fume_n without_o the_o help_n of_o external_a fire_n and_o if_o it_o be_v with_o some_o such_o spirituous_a and_o volatile_a exhalation_n that_o a_o mineral_n water_n as_o that_o of_o tunbridge_n or_o of_o islington_n be_v impregnate_v it_o be_v not_o hard_a to_o conceive_v that_o they_o may_v easy_o lose_v their_o chief_a virtue_n by_o the_o avolation_n of_o most_o or_o many_o of_o their_o fugitive_a part_n upon_o their_o be_v remove_v to_o a_o distance_n from_o the_o spring_n head_n and_o to_o make_v it_o probable_a that_o vitriolate_a corpuscle_n may_v be_v make_v to_o ascend_v without_o lose_v their_o nature_n i_o shall_v here_o mention_v a_o experiment_n that_o i_o devise_v to_o give_v some_o light_n in_o this_o matter_n i_o have_v often_o find_v by_o trial_n that_o a_o spirit_n rich_o impregnate_v with_o volatilise_v sulphur_n will_v with_o vitriol_n whether_o in_o the_o form_n of_o a_o powder_n or_o a_o solution_n produce_v in_o a_o trice_n a_o very_a dark_a or_o blackish_a colour_n and_o guess_v that_o in_o mercury_n turn_v by_o the_o addition_n of_o salt_n and_o vitriol_n into_o corrosive_a sublimate_n many_o of_o the_o vitriolate_a corpuscle_n may_v ascend_v with_o the_o mercurial_a one_o i_o take_v such_o a_o volatile_a sulphureous_a tincture_n as_o i_o have_v be_v mention_v which_o for_o this_o purpose_n ought_v to_o be_v deep_a and_o have_v drop_v it_o upon_o good_a sublimate_n i_o find_v it_o turn_v present_o of_o a_o very_a opacous_a colour_n to_o show_v also_o that_o to_o make_v a_o great_a dilatation_n or_o dispersion_n of_o the_o martial_a corpuscle_n of_o a_o ore_n or_o mineral_n there_o need_v no_o spirit_n of_o salt_n or_o the_o like_a distil_a menstruum_fw-la i_o procure_v from_o a_o copperas-work_n or_o place_n where_o vitriol_n be_v make_v by_o art_n some_o of_o the_o liquor_n they_o employ_v before_o they_o cast_v in_o iron_n that_o be_v corrode_v by_o it_o it_o may_v increase_v the_o weight_n and_o give_v solidity_n and_o some_o other_o quality_n to_o the_o design_a vitriol_n now_o thó_n this_o liquor_n be_v make_v without_o any_o chemical_a menstruum_fw-la bare_o by_o rain_n or_o snow-water_n that_o impregnate_v itself_o with_o saline_n or_o metalline_a particle_n in_o its_o passage_n through_o bed_n of_o marcasite_n that_o lie_v expose_v to_o the_o sun_n and_o air_n yet_o in_o this_o water_n such_o number_n of_o martial_a corpuscle_n be_v disperse_v that_o have_v shake_v four_o drop_n of_o it_o into_o 12_o ounce_n and_o a_o half_a of_o common_a water_n this_o liquor_n as_o i_o expect_v be_v thereby_o so_o impregnate_v that_o with_o powder_n of_o gall_n it_o present_o produce_v as_o deep_a a_o colour_n as_o good_a tunbridge_n water_n will_v have_v do_v so_o that_o suppose_v a_o drop_n of_o this_o liquor_n to_o weigh_v about_o a_o grain_n as_o by_o some_o trial_n purposely_o make_v we_o find_v it_o to_o do_v it_o appear_v that_o one_o part_n of_o the_o vitriolate_a water_n be_v able_a manifest_o to_o impregnate_n 1500_o part_n of_o common_a water_n and_o yet_o of_o these_o 4_o drop_n or_o grain_n of_o vitriolate_a liquor_n a_o considerable_a part_n may_v very_o probable_o be_v conclude_v from_o the_o way_n of_o its_o production_n to_o have_v be_v rain_n water_n as_o will_v easy_o be_v grant_v when_o i_o shall_v have_v add_v that_o to_o examine_v this_o supposition_n or_o
big_a exact_o stop_v by_o which_o mean_n i_o have_v they_o always_o in_o readiness_n to_o mingle_v with_o the_o mineral_n water_n and_o alter_v the_o colour_n of_o it_o if_o gall_n be_v able_a to_o do_v it_o almost_o in_o atrice_n whereas_o to_o draw_v the_o tincture_n of_o gall_n with_o simple_a water_n often_o take_v up_o several_a hour_n and_o the_o ting_a part_n be_v much_o weaken_v by_o be_v dilute_v by_o the_o menstruum_fw-la if_o you_o will_v have_v a_o tincture_n the_o powder_n of_o gall_n tie_v up_o close_o in_o a_o rag_n and_o with_o it_o hang_v in_o the_o liquor_n make_v the_o infusion_n less_o muddy_a if_o you_o be_v in_o haste_n and_o have_v none_o of_o the_o powder_n at_o hand_n you_o may_v scrape_v as_o much_o of_o a_o gall-apple_n as_o you_o need_v into_o the_o

be_v more_o apt_a to_o fly_v away_o than_o one_o will_v think_v the_o infusion_n become_v often_o unfit_a to_o alter_v the_o colour_n of_o the_o martial_a water_n whilst_o yet_o itself_o appear_v sufficient_o high_a colour_v upon_o which_o account_n i_o choose_v to_o make_v a_o tincture_n of_o gall_n not_o long_o before_o i_o mind_n to_o use_v it_o and_o if_o i_o employ_v dry_a gall_n to_o take_v powder_n that_o be_v not_o stale_a 3._o it_o be_v no_o safe_a way_n and_o may_v be_v very_o erroneous_a that_o be_v usual_o take_v in_o mix_v gall_n or_o their_o infusion_n with_o the_o water_n to_o be_v explore_v so_o careless_o as_o be_v wont_a to_o be_v do_v for_o those_o that_o be_v curious_a to_o make_v good_a ink_n will_v easy_o believe_v that_o much_o of_o the_o deepness_n of_o the_o colour_n depend_v upon_o the_o proportion_n of_o gall_n to_o the_o other_o ingredient_n and_o according_o that_o by_o put_v a_o much_o great_a or_o a_o much_o lesser_a quantity_n of_o gall_n into_o such_o a_o quantity_n of_o the_o mineral_n water_n the_o result_a colour_n may_v be_v more_o or_o less_o intense_a to_o obviate_v which_o inconvenience_n i_o take_v this_o course_n when_o the_o occasion_n deserve_v it_o i_o make_v my_o infusion_n of_o gall_n with_o a_o certain_a weight_n of_o the_o powder_n in_o a_o determinate_a weight_n of_o water_n as_o for_o instance_n i_o put_v about_o five_o gr_n of_o powder_a gall_n to_o sleep_v for_o so_o many_o hour_n in_o a_o ounce_n of_o water_n but_o if_o i_o make_v use_n of_o the_o dry_a powder_n than_o i_o be_o wont_a to_o put_v three_o or_o four_o grain_n into_o a_o ounce_n of_o the_o liquor_n to_o be_v examine_v which_o be_v a_o way_n far_o more_o certain_a than_o the_o common_a wherein_o the_o ingredient_n be_v aestimate_v but_o by_o guess_n i_o have_v have_v mention_v various_a proportion_n of_o powder_a gall_n to_o the_o same_o quantity_n of_o liquor_n because_o i_o have_v observe_v that_o there_o be_v real_o a_o great_a inequality_n among_o the_o mineral_n water_n in_o which_o it_o may_v be_v put_v and_o i_o have_v find_v by_o trial_n that_o in_o a_o ounce_n of_o the_o german_a spa_n a_o single_a grain_n of_o powder_n will_v immediate_o produce_v a_o sufficient_o deep_a purple_a colour_n it_o be_v a_o inconvenience_n that_o not_o only_a gall_n but_o the_o other_o drug_n hereafter_o to_o be_v mention_v impart_v a_o high_a tincture_n of_o their_o own_o to_o the_o common_a water_n they_o be_v infuse_v in_o and_o therefore_o it_o be_v to_o be_v wish_v and_o be_v fit_a to_o be_v endeavour_v that_o we_o have_v some_o drugg_n that_o without_o impart_v a_o colour_n to_o the_o common_a water_n it_o impregnate_v will_v afford_v a_o infusion_n fit_a to_o strike_v a_o blackish_a or_o a_o purple_a colour_n with_o martial_a water_n though_o it_o be_v useful_a yet_o it_o be_v not_o necessary_a to_o employ_v gall_n to_o produce_v a_o colour_n in_o the_o mineral_n water_n propose_v for_o beside_o that_o it_o be_v know_v that_o usual_o though_o not_o always_o as_o i_o have_v try_v the_o same_o thing_n may_v be_v do_v but_o somewhat_o more_o faint_o with_o oaken_a leave_n we_o may_v successful_o enough_o substitute_n for_o the_o same_o purpose_n some_o other_o astringent_a vegetable_n as_o dry_a red-rose_n leave_v the_o peel_n and_o as_o we_o have_v try_v the_o juice_n of_o pomegranate_n and_o what_o i_o find_v to_o be_v a_o notable_a styptic_a the_o blossom_n of_o the_o same_o plant_n which_o be_v vulgar_o call_v in_o the_o shop_n ballaustium_fw-la to_o which_o may_v be_v add_v

liquor_n 6._o in_o regard_n that_o the_o gall_n or_o other_o drug_n to_o be_v infuse_v in_o common_a water_n be_v not_o always_o of_o the_o same_o goodness_n or_o strength_n it_o be_v adviseable_a not_o so_o to_o trust_v to_o any_o determinate_a proportion_n of_o the_o pigment_n to_o the_o water_n as_o not_o to_o take_v in_o the_o help_n of_o the_o eye_n to_o judge_v by_o the_o colour_n of_o the_o tincture_n whether_o the_o liquor_n be_v due_o and_o not_o too_o much_o or_o too_o little_a impregnate_v 8._o whereas_o there_o be_v a_o intimation_n in_o the_o close_a of_o this_o thirteen_o article_n of_o the_o present_a sett_n of_o title_n that_o animal_n liquor_n may_v be_v employ_v to_o produce_v new_a colour_n with_o mineral_n water_n i_o give_v that_o hint_n not_o only_o because_o

sulphureous_a scent_n that_o be_v sometime_o perceive_v in_o tunbridge_n and_o some_o other_o water_n in_o their_o source_n may_v in_o part_n proceed_v from_o loose_a exhalation_n that_o casual_o

trial_n purposely_o make_v in_o more_o than_o one_o of_o these_o mineral_n water_n which_o to_o prevent_v fraud_n i_o send_v for_o to_o the_o spring_n themselves_o by_o servant_n of_o my_o own_o for_o tho'_o these_o carry_v their_o glass_n bottle_n along_o with_o they_o and_o have_v no_o other_o errand_n there_o but_o to_o fill_v and_o stop_v they_o careful_o yet_o by_o be_v transport_v less_o
