before_o instead_o of_o lose_v according_a to_o custom_n the_o little_a remain_n of_o colour_n that_o after_o many_o day_n stand_v it_o yet_o retain_v the_o colour_n begin_v again_o to_o increase_v though_o the_o viol_n be_v constant_o keep_v stop_v as_o before_o and_o that_o which_o make_v this_o regain_n of_o the_o colour_n seem_v more_o strange_a be_v that_o there_o stand_v just_a by_o it_o another_o viol_n furnish_v with_o the_o spirit_n and_o with_o file_n take_v out_o of_o the_o same_o parcel_n yet_o the_o liquor_n of_o this_o parcel_n continue_v colourless_a wherefore_o suspect_v that_o some_o accident_n may_v have_v happen_v whereby_o some_o little_a portion_n of_o air_n may_v have_v insinuate_v themselves_o through_o the_o cork_n of_o the_o alter_a liquor_n i_o cast_v up_o

this_o view_n i_o be_v confirm_v that_o the_o change_v late_o mention_v in_o one_o of_o the_o viol_n be_v not_o from_o the_o cork_n but_o from_o some_o unobvious_a cause_n for_o though_o this_o

just_a by_o it_o continue_v colourless_a wherefore_o to_o satisfy_v myself_o further_o i_o present_o go_v to_o a_o private_a place_n where_o i_o have_v in_o a_o cavity_n make_v in_o the_o thickness_n of_o a_o wall_n set_v aside_o two_o viol_n that_o several_a day_n before_o have_v quite_o lose_v their_o colour_n and_o my_o former_a surprise_n be_v increase_v when_o i_o find_v that_o one_o of_o

colour_n both_o these_o be_v fit_v for_o trial_n with_o the_o same_o spirit_n and_o file_n and_o the_o same_o day_n with_o the_o other_o abovementioned_a and_o the_o heat_n of_o the_o wether_n have_v

that_o though_o former_o the_o spirit_n keep_v its_o native_a colour_n better_o than_o i_o desire_v yet_o it_o have_v acquire_v a_o green_a colour_n which_o whether_o it_o will_v lose_v again_o by_o
