they_o may_v in_o their_o grosser_n and_o cruder_n
it_o will_v of_o itself_o continue_v in_o that_o state_n the_o two_o general_a way_n that_o the_o nature_n of_o the_o thing_n seem_v to_o suggest_v to_o he_o that_o consider_v it_o be_v either_o to_o

to_o weaken_v the_o sustain_a power_n of_o the_o menstruum_fw-la and_o thereby_o disable_v it_o to_o keep_v the_o metalline_a particle_n swim_v any_o long_o which_o fall_v of_o the_o desert_a part_n of_o the_o metal_n or_o other_o body_n do_v oftentimes_o the_o more_o easy_o ensue_v because_o in_o many_o case_n when_o the_o sustain_a particle_n of_o the_o menstruum_fw-la come_v to_o be_v too_o much_o weaken_v that_o prove_v a_o occasion_n to_o the_o metalline_a corpuscle_n disturb_v in_o the_o former_a motion_n that_o keep_v they_o separate_v to_o make_v occursion_n and_o coalition_n

on_o which_o the_o same_o precipitant_n that_o bring_v the_o swim_a particle_n of_o the_o metal_n to_o stick_v to_o one_o another_o do_v likewise_o by_o mortify_v or_o disable_n the_o saline_a

the_o liquor_n that_o in_o many_o precipitation_n there_o be_v make_v a_o coalition_n betwixt_o the_o small_a part_n of_o the_o precipitant_n and_o those_o of_o the_o dissolve_a metal_n or_o other_o body_n and_o frequent_o also_o with_o the_o saline_a spirit_n of_o the_o menstruum_fw-la may_v be_v easy_o show_v by_o the_o weight_n of_o the_o precipitate_v which_o though_o careful_o wash_v and_o dry_v often_o surpass_v and_o sometime_o very_o considerable_o that_o of_o your_o crude_a metal_n that_o be_v dissolve_v of_o which_o we_o late_o give_v a_o instance_n in_o aurum_fw-la fulminans_fw-la and_o precipitate_v silver_n &_o we_o may_v yet_o give_v a_o more_o conspicuous_a one_o in_o that_o which_o chemist_n call_v luna_n cornea_n for_o if_o have_v dissolve_v silver_n in_o good_a aqua_fw-la fortis_fw-la you_o precipitate_v it_o with_o the_o solution_n of_o sea-salt_n in_o fair_a water_n and_o from_o the_o very_a white_a precipitate_v wash_v the_o loose_a adhere_a salt_n the_o remain_a powder_n be_v dry_v and_o slow_o melt_v will_v look_v much_o less_o like_o a_o metalline_a body_n than_o like_o a_o piece_n of_o horn_n whence_o also_o it_o take_v its_o name_n so_o considerable_a be_v the_o additament_n of_o the_o saline_a to_o the_o metalline_a particle_n and_o that_o part_n of_o such_o additament_n be_v retain_v may_v not_o only_o be_v find_v by_o weigh_v but_o in_o divers_a case_n may_v be_v argue_v from_o what_o be_v obvious_a to_o the_o eye_n as_o if_o you_o dissolve_v mercury_n in_o aqua_fw-la fortis_fw-la and_o into_o the_o philtrated_a solution_n drop_v spirit_n of_o salt_n or_o salt-water_n or_o a_o urinous_a spirit_n as_o of_o sal_fw-la ammoniac_a you_o will_v have_v a_o very_a white_a precipitate_v but_o if_o instead_o of_o any_o of_o these_o you_o drop-in_a deliquated_a salt_n of_o tartar_n your_o precipitate_v will_n be_v of_o a_o brick_n or_o orange_n colour_n from_o which_o experiment_n and_o some_o other_o i_o will_v glad_o take_v a_o rise_n to_o persuade_v chemist_n and_o physician_n that_o it_o be_v not_o so_o indifferent_a as_o those_o seem_v to_o think_v who_o look_v on_o precipitation_n but_o as_o a_o kind_n of_o comminution_n by_o what_o mean_v the_o precipitation_n be_v perform_v for_o by_o reason_n of_o the_o strict_a adhesion_n of_o divers_a saline_a particle_n of_o the_o precipitant_n and_o the_o solvent_a the_o precipitate_v body_n notwithstanding_o all_o the_o wont_a ablution_n may_v have_v its_o quality_n much_o diversify_v by_o those_o of_o the_o particle_n of_o the_o liquor_n when_o these_o be_v fit_v to_o stick_v very_o fast_o to_o it_o which_o last_o word_n i_o add_v because_o though_o that_o sometime_o happen_v yet_o it_o do_v not_o always_o there_o be_v a_o geat_a difference_n than_o every_o body_n take_v notice_n of_o between_o precipitation_n as_o you_o will_v be_v induce_v to_o think_v if_o you_o precipitate_v the_o solution_n of_o silver_n with_o copper_n

you_o will_v think_v it_o probable_a that_o it_o be_v not_o all_o one_o whether_o to_o dissolve_a mercury_n or_o silver_n you_o employ_v the_o subtle_a distil_a spirit_n of_o salt_n or_o the_o gross_a
