easy_o pardon_v i_o if_o i_o conclude_v it_o not_o abrupt_o but_o with_o the_o recital_n of_o a_o experiment_n which_o have_v have_v the_o honour_n to_o be_v see_v as_o to_o the_o main_a part_n of_o

make_v with_o good_a spirit_n of_o vinegar_n a_o solution_n of_o coral_n so_o strong_a that_o when_o it_o be_v filtrate_v and_o cool_v it_o will_v common_o after_o some_o time_n begin_v to_o have_v a_o kind_n of_o sediment_n at_o the_o bottom_n the_o clear_a liquor_n i_o gentle_o pour_v off_o when_o the_o experiment_n be_v to_o be_v make_v and_o to_o this_o i_o put_v a_o convenient_a

careful_o look_v to_o but_o to_o dispatch_v the_o whole_a experiment_n in_o a_o short_a time_n i_o take_v a_o little_a strong_a spirit_n of_o nitre_n which_o perhaps_o be_v not_o needful_a if_o good_a aqua_fw-la fortis_fw-la be_v at_o hand_n and_o put_v about_o a_o equal_a or_o other_o convenient_a quantity_n of_o it_o to_o this_o mixture_n i_o nimble_o stir_v it_o and_o the_o spirit_n together_o
