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 to_o be_v that_o be_v as_o it_o be_v the_o cadaver_n or_o to_o employ_v chemical_a term_n the_o deliquated_a caput_n mortuum_n of_o the_o shine_a substance_n do_v not_o yet_o contain_v something_o as_o well_o luminous_a as_o saline_n experiment_n i._n to_o satisfy_v myself_o about_o this_o i_o cause_v this_o liquor_n to_o be_v put_v
other_o concretes_n also_o may_v be_v by_o the_o operation_n of_o the_o fire_n this_o conjecture_n of_o i_o be_v favour_v by_o some_o experiment_n i_o have_v make_v many_o year_n before_o and_o impart_v to_o some_o inquisitive_a man_n whereby_o two_o distil_a liquor_n be_v make_v bare_o by_o their_o mutual_a reaction_n to_o afford_v great_a store_n of_o a_o earthly_a and_o very_a fix_a

best_a gather_v from_o the_o phaenomena_n themselves_o of_o the_o trial_n which_o i_o shall_v proceed_v to_o set_v down_o a_o succinct_a account_n of_o as_o soon_o as_o i_o have_v premise_v to_o make_v way_n for_o it_o that_o by_o a_o essential_a oil_n chemist_n be_v wont_a to_o mean_v such_o a_o fine_a oleagenous_a liquor_n as_o to_o prevent_v empyreume_n and_o feculent_a part_n have_v be_v

because_o it_o be_v more_o easy_a to_o discern_v it_o by_o its_o self-coagulating_a property_n not_o to_o be_v sophisticated_a and_o have_v put_v it_o into_o a_o glass_n retort_n of_o a_o convenient_a

be_v both_o congruous_a to_o our_o hypothesis_n and_o in_o themselves_o observable_a 1._o as_o pure_a as_o the_o essential_a or_o as_o some_o spagyrist_n style_v they_o the_o aetherial_a oil_n of_o

only_o the_o first_o distillation_n leave_v a_o substance_n black_a like_a pitch_n at_o the_o bottom_n of_o the_o retort_n but_o at_o every_o one_o of_o the_o follow_a distillation_n such_o a_o substance_n be_v either_o separate_v or_o generate_v 2._o though_o after_o a_o distillation_n or_o two_o it_o seem_v likely_a that_o this_o pitchy_a substance_n will_v be_v find_v every_o time_n less_o and_o less_o which_o make_v the_o person_n former_o mention_v tell_v i_o that_o he_o suppose_v within_o ten_o or_o at_o most_o twelve_o distillation_n in_o all_o if_o one_o shall_v make_v so_o many_o this_o which_o he_o look_v upon_o as_o a_o earthy_a recrement_n will_v be_v quite_o separate_v and_o leave_v the_o oil_n a_o most_o pure_a and_o homogeneous_a liquor_n yet_o i_o that_o as_o i_o former_o intimate_v look_v upon_o this_o black_a stuff_n not_o as_o a_o separate_a excrement_n but_o generate_v substance_n cause_v the_o distillation_n to_o be_v repeat_v till_o they_o have_v

well_o be_v that_o the_o oil_n to_o be_v distil_v do_v sensible_o from_o time_n to_o time_n decrease_v in_o bulk_n partly_o by_o reason_n of_o the_o recess_n of_o that_o portion_n of_o the_o oil_n which_o can_v not_o but_o be_v dissipate_v and_o lose_v in_o so_o many_o cohobation_n and_o partly_o and_o indeed_o chief_o by_o the_o loss_n of_o so_o much_o oil_n as_o be_v transmute_v into_o

and_o especial_o towards_o the_o latter_a end_n of_o the_o distillation_n it_o be_v often_o necessary_a to_o employ_v a_o scarce_o credible_a degree_n of_o fire_n to_o elevate_v all_o that_o be_v

often_o sudden_o break_v usual_o not_o without_o much_o noise_n and_o sometime_o with_o such_o violence_n as_o to_o shake_v and_o endanger_v the_o retort_n which_o once_o by_o this_o contest_v be_v
