but_o what_o have_v be_v above_o recite_v be_v not_o all_o that_o i_o think_v fit_a to_o try_v with_o the_o shine_a matter_n that_o i_o tell_v you_o we_o dissolve_v in_o spirit_n of_o wine_n for_o after_o have_v as_o i_o late_o recite_v bring_v one_o grain_n to_o impregnate_n between_o four_o and_o five_o ounce_n of_o alcohol_n as_o the_o chemist_n call_v the_o high_a rectify_a spirit_n of_o

the_o conical_a figure_n of_o its_o bottom_n after_o this_o i_o prosecute_v the_o experiment_n a_o good_a way_n further_o increase_a the_o proportion_n of_o the_o water_n to_o fresh_a impregnated_a spirit_n and_o i_o find_v what_o perhaps_o you_o will_v think_v strange_a that_o one_o part_n of_o the_o noctiluca_n be_v first_o dissolve_v in_o alcohol_n of_o wine_n and_o afterward_o brisk_o shake_v into_o a_o convenient_a quantity_n of_o water_n render_v luminous_a as_o much_o liquor_n as_o upon_o calculation_n amount_v to_o four_o hundred_o thousand_o time_n its_o weight_n and_o this_o

but_o very_o faint_o and_o when_o the_o glass_n be_v at_o rest_n much_o less_o than_o a_o minute_n of_o a_o hour_n the_o light_n will_v reach_v but_o a_o little_a way_n downward_o in_o the_o water_n and_o yet_o be_v there_o so_o dim_a as_o to_o be_v scarce_o discernible_a whereas_o in_o our_o experiment_n not_o only_o the_o agitate_a liquor_n appear_v luminous_a throughout_o but_o the_o light_n

if_o this_o experiment_n have_v be_v further_a and_o further_o prosecute_v the_o luminousness_n will_v have_v still_o extend_v to_o great_a and_o great_a quantity_n of_o water_n i_o shall_v add_v that_o when_o i_o increase_v the_o proportion_n of_o this_o liquor_n to_o the_o noctilucal_n matter_n to_o be_v disperse_v through_o it_o by_o put_v in_o near_o three_o or_o four_o ounce_n of_o

take_v some_o fresh_a spirit_n and_o shake_v it_o into_o such_o a_o quantity_n of_o water_n as_o i_o think_v it_o may_v serve_v to_o impregnate_n i_o find_v by_o supputation_n that_o the_o luminous_a

a_o discernible_a colour_n in_o a_o hundred_o twenty_o five_o thousand_o part_n of_o water_n to_o what_o have_v be_v say_v i_o shall_v add_v these_o three_o circumstance_n which_o may_v increase_v the_o strangeness_n of_o the_o experiment_n 1._o the_o first_o be_v that_o i_o here_o only_o deliver_v the_o manifest_a impregnation_n of_o the_o water_n itself_o which_o be_v a_o gross_a and_o tangible_a liquor_n by_o the_o disperse_a particle_n of_o the_o noctilucal_n matter_n but_o have_v make_v no_o estimate_n of_o the_o incomparable_o great_a expansion_n of_o the_o light_n that_o from_o the_o matter_n include_v in_o the_o phial_n illuminate_v the_o ambient_fw-la air_n to_o a_o considerable_a distance_n from_o it_o though_o by_o reason_n the_o darken_a room_n be_v not_o great_a i_o be_v disable_v to_o make_v a_o estimate_n how_o far_o the_o enlighten_v sphere_n of_o air_n may_v have_v extend_v 2._o the_o second_o be_v that_o this_o experiment_n be_v not_o favourable_o make_v but_o rather_o invidious_o since_o we_o purposely_o weigh_v out_o somewhat_o less_o of_o the_o lucid_a matter_n and_o now_o and_o then_o more_o of_o the_o water_n than_o the_o precise_a quantity_n that_o calculation_n suppose_v that_o i_o may_v be_v sure_a the_o experiment_n be_v make_v severe_o enough_o 3._o and_o last_o upon_o search_n i_o find_v that_o the_o grain_n of_o icy_a phosphorus_n that_o be_v first_o put_v into_o the_o spirit_n of_o wine_n we_o make_v use_v of_o all_o this_o while_n be_v not_o though_o after_o so_o long_a a_o time_n total_o dissolve_v a_o small_a fragment_n amount_v to_o about_o a_o eight_o part_n if_o not_o more_o remain_v at_o the_o bottom_n of_o the_o phial_n upon_o which_o have_v pour_v some_o fresh_a alcohol_n of_o wine_n and_o keep_v it_o a_o while_n in_o a_o little_a heat_n to_o further_o the_o dissolution_n i_o find_v that_o liquor_n do_v as_o i_o think_v it_o will_v grow_v very_o luminous_a when_o drop_v into_o common_a water_n so_o that_o it_o seem_v probable_a that_o if_o the_o whole_a grain_n of_o icy_a phosphorus_n have_v be_v dissolve_v at_o first_o in_o the_o spirit_n of_o wine_n it_o will_v have_v impregnate_v above_o six_o hundred_o thousand_o time_n its_o weight_n of_o water_n sufficient_a to_o make_v it_o shine_v sect_n ix_o i_o come_v now_o to_o another_o way_n by_o which_o i_o think_v the_o great_a subtlety_n of_o part_n in_o our_o noctilucal_n matter_n may_v appear_v with_o good_a advantage_n and_o possible_o you_o will_v think_v by_o the_o success_n that_o i_o miss_v not_o of_o what_o i_o expect_v from_o the_o intend_a trial_n experiment_n i._n we_o careful_o weigh_v out_o a_o small_a lump_n of_o our_o shine_a matter_n amount_v to_o three_o grain_n and_o have_v purposely_o break_v it_o into_o divers_a lesser_a fragment_n perhaps_o six_o or_o seven_o at_o least_o we_o lay_v they_o upon_o a_o flat_a bottom_v glass_n that_o be_v broad_a at_o the_o top_n than_o the_o bottom_n and_o shallow_a too_o not_o be_v near_o a_o inch_n deep_a that_o the_o matter_n may_v be_v more_o full_o expose_v to_o the_o free_a air._n this_o glass_n we_o place_v in_o a_o south_n window_n lay_v it_o very_o shelve_v that_o the_o liquor_n to_o be_v produce_v by_o its_o resolution_n in_o the_o moist_a air_n may_v present_o run_v down_o and_o not_o hinder_v the_o free_a evaporation_n of_o the_o remain_a matter_n in_o which_o posture_n of_o the_o glass_n we_o have_v also_o another_o aim_n to_o be_v hereafter_o mention_v the_o vessel_n be_v thus_o place_v about_o ten_o of_o the_o clock_n at_o night_n all_o the_o fragment_n of_o the_o noctiluca_n shine_v brisk_o and_o so_o continue_v to_o do_v till_o most_o of_o they_o be_v resolve_v into_o other_o substance_n and_o the_o big_a of_o they_o continue_v to_o shine_v till_o they_o be_v reduce_v to_o such_o a_o smallness_n that_o they_o will_v scarce_o have_v be_v see_v have_v not_o their_o own_o light_n make_v they_o visible_a but_o the_o main_a thing_n that_o i_o be_o to_o take_v notice_n of_o in_o this_o experiment_n and_o which_o perhaps_o will_v somewhat_o surprise_v you_o be_v that_o so_o little_a quantity_n of_o noctilucal_n matter_n continue_v to_o emit_v visible_a fume_n for_o a_o good_a many_o more_o than_o a_o hundred_o and_o fifty_o hour_n and_o this_o with_o circumstance_n that_o make_v the_o thing_n more_o strange_a 1._o as_o first_o that_o this_o smoke_n be_v not_o only_o visible_a but_o manifest_a and_o that_o as_o well_o in_o the_o night_n as_o i_o often_o observe_v from_o time_n to_o time_n as_o in_o the_o day_n 2._o second_o that_o the_o several_a parcel_n of_o matter_n do_v each_o emit_v there_o fume_n all_o at_o once_o as_o if_o it_o be_v from_o so_o many_o little_a chimney_n 3._o three_o that_o this_o smoke_n be_v so_o copious_a and_o withal_o so_o tenacious_a that_o it_o will_v easy_o retain_v the_o form_n of_o smoke_n at_o a_o considerable_a distance_n from_o the_o body_n that_o emit_v it_o so_o that_o as_o i_o walk_v to_o and_o fro_o in_o the_o room_n a_o careless_a look_n towards_o the_o glass_n will_v often_o discover_v it_o to_o i_o and_o sometime_o it_o will_v manifest_o appear_v at_o a_o distance_n that_o i_o estimate_v to_o be_v near_o a_o foot_n from_o the_o matter_n that_o afford_v it_o i_o shall_v now_o add_v to_o another_o purpose_n the_o follow_a circumstance_n namely_o 1._o first_o that_o the_o motion_n of_o the_o smoke_n be_v swift_a enough_o consider_v that_o it_o have_v no_o channel_n or_o chimney_n to_o assist_v it_o it_o be_v not_o always_o nor_o for_o the_o most_o part_n direct_o upward_o but_o sometime_o horizontal_a sometime_o downward_o sometime_o towards_o the_o right_a hand_n and_o sometime_o towards_o the_o left_a as_o if_o the_o motion_n of_o the_o fume_n have_v be_v determine_v by_o the_o situation_n of_o those_o part_n of_o the_o noctilucal_n fragment_n by_o which_o they_o be_v emit_v and_o as_o it_o be_v discharge_v i_o use_v this_o last_o expression_n because_o take_v pleasure_n to_o watch_v attentive_o the_o circumstance_n of_o our_o delightful_a experiment_n i_o think_v i_o many_o time_n observe_v a_o kind_n of_o palpitation_n or_o aestuation_n in_o the_o little_a shine_a fragment_n which_o i_o gather_v from_o the_o apparent_a great_a inequality_n i_o perceive_v in_o the_o plenty_n of_o the_o smoke_n that_o be_v emit_v at_o several_a time_n all_o of_o they_o perhaps_o within_o the_o compass_n of_o a_o minute_n or_o two_o but_o on_o this_o i_o forbear_v to_o discourse_v till_o i_o shall_v have_v make_v further_a observation_n and_o therefore_o i_o shall_v proceed_v to_o take_v notice_n of_o one_o circumstance_n more_o in_o our_o experiment_n which_o be_v 2._o second_o that_o even_o in_o the_o latter_a part_n of_o it_o after_o the_o shine_a matter_n have_v be_v so_o long_o expose_v to_o the_o air_n it_o emit_v a_o smell_n strong_a enough_o which_o seem_v to_o be_v cause_v by_o odorous_a exhalation_n distinct_a from_o the_o visible_a fume_n sect_n x._o and_o now_o it_o be_v time_n that_o i_o give_v you_o some_o account_n of_o the_o reason_n that_o i_o but_o point_v at_o before_o why_o i_o choose_v such_o a_o glass_n and_o keep_v it_o in_o a_o shelve_v posture_n this_o i_o do_v that_o i_o may_v not_o lose_v but_o preserve_v the_o liquor_n which_o i_o know_v will_v fall_v from_o the_o saline_n part_n of_o the_o shine_a matter_n which_o liquor_n i_o think_v fit_a to_o examine_v in_o order_n to_o discover_v certain_a thing_n particular_o whether_o the_o limpid_a water_n as_o it_o appear_v
