this_o we_o have_v observe_v in_o i_o know_v not_o how_o many_o tincture_n draw_v with_o spirit_n of_o wine_n from_o jalap_n guaicum_fw-la and_o several_a other_o vegetable_n and_o not_o only_o in_o

can_v give_v you_o of_o the_o easy_a production_n of_o redness_n by_o the_o operation_n of_o saline_n spirit_n as_o well_o as_o of_o spirit_n of_o wine_n i_o remember_v two_o or_o three_o of_o those_o

be_v very_o well_o worth_a a_o serious_a inquiry_n which_o i_o shall_v therefore_o recommend_v to_o pyrophilus_n and_o his_o ingenious_a friend_n experiment_n xxxvii_o it_o may_v seem_v somewhat_o strange_a that_o if_o you_o take_v the_o crimson_a solution_n of_o cochineel_n or_o the_o juice_n of_o black_a cherry_n and_o of_o some_o other_o vegetable_n that_o afford_v the_o like_a colour_n

may_v perhaps_o plausible_o enough_o say_v on_o this_o occasion_n that_o if_o we_o consider_v the_o case_n a_o little_a more_o attentive_o we_o may_v take_v notice_n that_o the_o action_n of_o the_o

in_o such_o body_n the_o yellow_a seem_v to_o be_v but_o a_o diluted_a red._n and_o according_o alcalizate_a solution_n and_o urinous_a spirit_n which_o seem_v dispose_v to_o deepen_v the_o colour_n of_o the_o juice_n and_o liquor_n of_o most_o vegetable_n will_v not_o only_o restore_v the_o solution_n of_o cochineel_n and_o the_o infusion_n of_o brazil_n to_o the_o crimson_a whence_o the_o

only_o heighten_v the_o yellow_a juice_n of_o mad_a into_o red_a but_o advance_v the_o red_a infusion_n of_o brazil_n to_o a_o crimson_a but_o i_o know_v not_o whether_o it_o will_v not_o be_v much_o safe_a to_o derive_v these_o change_n from_o varied_a texture_n than_o certain_a kind_n of_o body_n and_o you_o will_v perhaps_o think_v it_o worth_a while_n that_o i_o shall_v add_v on_o this_o

they_o as_o may_v be_v easy_o make_v appear_v by_o many_o of_o the_o experiment_n already_o set_v down_o in_o this_o treatise_n and_o though_o allom_n be_v of_o a_o acid_n nature_n its_o solution_n

i_o do_v but_o why_o i_o do_v it_o i_o consider_v then_o that_o the_o work_n of_o the_o former_a experiment_n be_v either_o to_o change_v the_o colour_n of_o a_o body_n into_o another_o or_o quite_o to_o destroy_v it_o without_o give_v it_o a_o successor_n but_o i_o have_v a_o mind_n to_o give_v you_o also_o a_o way_n whereby_o to_o turn_v a_o body_n endue_v with_o one_o colour_n into_o two_o body_n of_o colour_n as_o well_o as_o consistency_n very_o distinct_a from_o each_o other_o and_o that_o by_o the_o help_n of_o a_o body_n that_o have_v itself_o no_o colour_n at_o all_o in_o order_n to_o this_o i_o remember_v that_o find_v the_o acidity_n of_o spirit_n of_o vinegar_n to_o be_v whole_o destory_v by_o its_o work_n upon_o minium_n or_o calcine_v lead_n whereby_o the_o salin_n particle_n of_o the_o menstruum_fw-la have_v their_o taste_n and_o nature_n quite_o alter_v i_o have_v among_o other_o conjecture_n i_o have_v build_v upon_o that_o change_n right_o conclude_v that_o the_o solution_n of_o lead_n in_o spirit_n of_o vinegar_n will_v alter_v the_o colour_n of_o the_o juice_n and_o infusion_n of_o several_a plant_n much_o after_o the_o like_a manner_n that_o i_o have_v find_v oil_n of_o tartar_n to_o do_v and_o according_o i_o be_v quick_o satisfy_v upon_o trial_n that_o the_o infusion_n of_o rose-leaf_n will_v by_o a_o small_a quantity_n of_o this_o solution_n well_o mingle_v with_o it_o be_v immediate_o turn_v into_o a_o somewhat_o sad_a green_n and_o further_o i_o have_v often_o find_v that_o oil_n of_o vitriol_n though_o a_o potent_o acid_n menstruum_fw-la will_v yet_o praecipitate_v many_o body_n both_o mineral_n and_o other_o dissolve_v not_o only_o in_o aqua_fw-la fortis_fw-la as_o some_o chemist_n have_v observe_v but_o particular_o in_o spirit_n of_o vinegar_n and_o i_o have_v further_o find_v that_o the_o calces_fw-la or_o powder_n precipitate_v by_o this_o liquor_n be_v usual_o fair_a and_o white_a lay_v these_o thing_n together_o it_o be_v not_o difficult_a to_o conclude_v that_o if_o upon_o a_o good_a tincture_n of_o red_a rose-leaf_n make_v with_o fair_a water_n i_o drop_v a_o pretty_a quantity_n of_o a_o strong_a

will_v reduce_v it_o to_o and_o that_o if_o then_o i_o add_v a_o convenient_a quantity_n of_o good_a oil_n of_o vitriol_n this_o last_o name_v liquor_n will_v have_v two_o distinct_a operation_n upon_o the_o mixture_n the_o one_o that_o it_o will_v praecipitate_v that_o resolve_a lead_n in_o the_o form_n of_o a_o white_a powder_n the_o other_o
