salt_n i_o have_v employ_v as_o the_o solution_n of_o salt_n of_o tartar_n of_o pot-ash_n of_o common_a wood-ash_n limewater_n etc._n etc._n will_v immediate_o change_v the_o blue_a syrup_n into_o a_o

that_o shall_v e'vn_v before_o the_o ink_n be_v dry_a appear_v partly_o blue_a partly_o red_a and_o partly_o green_a but_o though_o the_o latter_a part_n of_o the_o experiment_n succeed_v not_o well_o

this_o precipitate_v substance_n be_v it_o be_v not_o needful_a now_o to_o inquire_v in_o this_o place_n and_o in_o another_o i_o have_v show_v you_o that_o notwithstanding_o its_o colour_n and_o

xxii_o our_o next_o experiment_n pyrophilus_n will_v perhaps_o seem_v to_o be_v of_o a_o contrary_a nature_n to_o the_o two_o former_a make_v upon_o syrup_n of_o violet_n and_o juice_n of_o

greenish_a liquor_n become_v blue_a the_o hint_n of_o this_o experiment_n be_v give_v we_o by_o the_o practice_n of_o some_o italian_a painter_n who_o be_v wont_n to_o counterfeit_n ultra-marine_a azure_a as_o they_o call_v it_o by_o grind_v verdigrease_n with_o salarmoniack_a and_o some_o other_o saline_n ingredient_n and_o let_v they_o rot_v as_o they_o imagine_v for_o a_o good_a while_n together_o in_o a_o dunghill_n we_o suppose_v that_o the_o change_n of_o colour_n wrought_v in_o the_o verdigrease_n by_o this_o way_n of_o preparation_n must_v proceed_v from_o the_o action_n of_o certain_a volatile_a and_o alcalizate_a salt_n abound_v in_o some_o of_o the_o mingle_a concretes_n and_o bring_v to_o make_v a_o further_a dissolution_n of_o the_o copper_n abound_v in_o the_o verdigrease_n and_o therefore_o we_o conjecture_v that_o if_o both_o the_o verdigrease_n and_o such_o salt_n be_v dissolve_v in_o fair_a water_n the_o small_a part_n of_o both_o be_v therein_o more_o subdivide_v and_o set_v at_o liberty_n will_v have_v better_a access_n to_o each_o other_o and_o thereby_o incorporate_v much_o the_o more_o sudden_o and_o according_o we_o find_v that_o if_o upon_o a_o strong_a solution_n of_o good_a french_a verdigrease_n for_o it_o be_v that_o we_o be_v wont_n to_o employ_v as_o the_o best_a you_o pour_v a_o just_a quantity_n of_o oil_n of_o tartar_n and_o shake_v they_o well_o together_o you_o shall_v immediate_o see_v a_o notable_a change_n of_o colour_n and_o the_o mixture_n will_v grow_v thick_a and_o not_o transparent_a but_o if_o you_o stay_v a_o while_n till_o the_o grosser_n part_n be_v precipitate_v to_o and_o settle_v in_o the_o bottom_n you_o may_v obtain_v a_o clear_a liquor_n of_o a_o very_a lovely_a colour_n and_o exceed_v delightful_a to_o the_o eye_n but_o you_o must_v have_v a_o care_n to_o drop_v in_o a_o competent_a quantity_n of_o oil_n of_o tartar_n for_o else_o the_o colour_n will_v not_o be_v so_o deep_a and_o rich_a and_o if_o instead_o of_o this_o oil_n you_o employ_v a_o clear_a lixivium_n of_o pot-ash_n you_o may_v have_v a_o azure_a somewhat_o light_a or_o pale_a than_o and_o therefore_o differ_v from_o the_o former_a and_o if_o instead_o of_o either_o of_o these_o liquor_n you_o make_v use_v of_o spirit_n of_o urine_n or_o of_o hartshorn_n you_o may_v according_a to_o the_o quantity_n and_o quality_n of_o the_o spirit_n you_o pour_v in_o obtain_v some_o further_a variety_n though_o scarce_o considerable_a of_o caeruleous_a liquor_n and_o yet_o late_o by_o the_o help_n of_o this_o urinous_a spirit_n
