by_o digestion_n you_o will_v meet_v with_o present_o wherefore_o i_o shall_v now_o make_v only_o this_o observation_n from_o what_o have_v be_v deliver_v that_o in_o these_o operation_n there_o

another_o colour_n experiment_n xxxi_o among_o the_o several_a change_n of_o colour_n which_o body_n acquire_v or_o disclose_v by_o digestion_n it_o it_o very_o remarkable_a that_o chemist_n find_v a_o redness_n rather_o than_o any_o other_o colour_n in_o most_o of_o the_o tincture_n they_o draw_v and_o even_o in_o the_o more_o gross_a solution_n they_o make_v of_o almost_o all_o concretes_n

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

for_o a_o competent_a time_n you_o make_v a_o further_a comminution_n of_o the_o oil_n into_o far_o more_o numerous_a and_o smaller_n globuli_fw-la and_o thereby_o confound_v it_o also_o better_a with_o the_o water_n the_o mixture_n will_v appear_v of_o a_o much_o great_a whiteness_n and_o almost_o like_a milk_n whereas_o if_o the_o glass_n be_v a_o while_n let_v alone_o the_o colour_n will_v by_o degree_n impair_v as_o the_o oily_a globe_n grow_v few_o and_o bigger_n and_o at_o length_n will_v quite_o vanish_v leave_v both_o the_o liquor_n distinct_a and_o diaphanous_a as_o before_o and_o such_o a_o trial_n have_v not_o ill_o succeed_v when_o instead_o of_o the_o colourless_a oil_n of_o turpentine_n i_o take_v a_o yellow_a mixture_n make_v of_o a_o good_a proportion_n of_o crude_a
