32_o page_n of_o my_o description_n of_o helioscope_n to_o publish_v a_o counterpoise_n for_o liquor_n i_o shall_v only_o explain_v several_a way_n by_o the_o help_n of_o these_o counterpoise_n to_o do_v whatsoever_o can_v be_v require_v as_o to_o the_o manner_n and_o quantity_n of_o supply_a oil_n to_o the_o flame_n the_o chief_a design_n of_o the_o counterpoise_n in_o this_o inquisition_n be_v to_o keep_v the_o superficies_n of_o the_o liquor_n whether_o oil_n spirit_n of_o wine_n oil_n of_o turpentine_n or_o the_o like_a whatever_o quantity_n there_o be_v in_o the_o vessel_n always_o to_o the_o same_o height_n so_o that_o the_o say_v pabulum_fw-la shall_v always_o be_v equal_o distant_a from_o the_o bottom_n of_o the_o flame_n and_o the_o wick_n or_o flame_n be_v once_o place_v at_o a_o convenient_a height_n or_o distance_n above_o the_o superficies_n of_o the_o oil_n shall_v not_o be_v desert_v by_o the_o say_a superficies_n till_o the_o whole_a quantity_n be_v consume_v but_o it_o be_v as_o easy_a to_o contrive_v it_o to_o supply_v it_o by_o decrease_v or_o increase_v degree_n which_o be_v convenience_n that_o none_o of_o all_o the_o lamp_n i_o have_v ever_o yet_o meet_v with_o have_v have_v that_o be_v tolerable_a for_o use_v the_o most_o ingenious_a be_v that_o which_o be_v common_o know_v by_o the_o name_n of_o cardan_n lamp_n as_o be_v publish_v and_o very_o probable_o invent_v by_o cardan_n which_o do_v in_o some_o manner_n supply_v the_o waste_n and_o decay_n of_o the_o oil_n cause_v by_o the_o flame_n consumption_n but_o than_o it_o be_v subject_a to_o a_o great_a many_o inconvenience_n which_o make_v it_o intolerable_a and_o disused_a the_o first_o be_v though_o it_o do_v supply_v the_o defect_n of_o the_o oil_n to_o the_o wick_n yet_o it_o do_v it_o not_o constant_o and_o equal_o but_o by_o start_n and_o glut_v for_o after_o the_o receptacle_n by_o the_o wick_n be_v fill_v the_o superficies_n of_o the_o oil_n continue_v to_o sink_v by_o degree_n a_o considerable_a space_n below_o the_o flame_n before_o there_o be_v any_o more_o supply_v add_v from_o the_o great_a magazine_n or_o repository_n and_o till_o the_o air_n can_v break_v in_o which_o it_o do_v very_o unequal_o so_o that_o there_o sometime_o come_v down_o so_o great_a a_o quantity_n that_o the_o receptacle_n be_v over-filled_n and_o the_o flame_n extinguish_v and_o these_o glut_v be_v more_o unequal_a the_o big_a the_o magazine_n be_v in_o proportion_n to_o the_o receptacle_n by_o the_o flame_n and_o the_o more_o the_o quantity_n of_o the_o oil_n be_v that_o be_v suspend_v and_o the_o more_o the_o air_n space_n be_v above_o the_o oil_n and_o the_o more_o tenacious_a or_o sluggish_a the_o constitution_n of_o the_o oil_n be_v the_o second_o inconvenience_n of_o cardan_n lamp_n be_v that_o the_o air_n be_v apt_a to_o rarify_v it_o with_o heat_n so_o as_o sometime_o to_o drive_v down_o so_o much_o oil_n as_o to_o overflow_v the_o receptacle_n and_o choke_v the_o flame_n the_o three_o inconvenience_n be_v that_o the_o wick_n by_o the_o sink_n of_o the_o oil_n do_v soon_o decay_v the_o flame_n be_v sometime_o a_o little_a high_o and_o sometime_o low_a upon_o the_o wick_n for_o if_o the_o wick_n rise_v up_o into_o the_o hollow_a dead_a part_n of_o the_o cone_n of_o the_o flame_n the_o stream_n and_o coal_n of_o the_o oil_n will_v be_v so_o cake_v together_o as_o to_o dead_a the_o flame_n and_o much_o to_o diminish_v the_o light_n and_o heat_n thereof_o whereas_o if_o the_o wick_n be_v but_o short_a and_o suffer_v only_o to_o go_v but_o a_o very_a little_a within_o the_o under-superficies_n of_o the_o flame_n it_o will_v not_o be_v so_o stop_v and_o cake_v with_o those_o feculency_n the_o reason_n of_o which_o be_v evident_a for_o the_o flame_n as_o i_o former_o prove_v be_v nothing_o but_o the_o part_n of_o the_o oil_n rarefy_v and_o raise_v by_o heat_n into_o the_o form_n of_o a_o vapour_n smoke_n or_o steam_n the_o free_a air_n that_o incompass_v this_o steam_n keep_v it_o into_o a_o cylindrical_a form_n and_o by_o its_o dissolve_v property_n prey_v upon_o or_o dissolve_v those_o part_n of_o it_o that_o be_v outward_o and_o next_o to_o the_o air_n so_o as_o by_o the_o say_a dissolution_n it_o continue_v the_o heat_n and_o produce_v the_o light_n which_o we_o observe_v but_o those_o part_n of_o the_o body_n of_o steam_n that_o rise_v from_o the_o wick_n which_o be_v in_o the_o middle_n and_o not_o contiguous_a to_o the_o outward_a air_n be_v not_o dissolve_v or_o turn_v into_o shine_a flame_n by_o the_o air_n till_o they_o rise_v towards_o the_o top_n of_o the_o cone_n of_o flame_n where_o the_o free_a air_n can_v come_v to_o reach_v and_o so_o to_o dissolve_v they_o and_o thence_o gather_v about_o the_o wick_n in_o the_o centre_n of_o the_o cone_n of_o flame_n they_o choke_v clog_n and_o quite_o stifle_v it_o that_o the_o flame_n will_v quick_o go_v out_o that_o this_o be_v so_o any_o one_o may_v easy_o find_v if_o he_o examine_v the_o flame_n of_o a_o lamp_n or_o candle_n by_o the_o help_n of_o a_o piece_n of_o glass_n for_o by_o the_o transparency_n thereof_o he_o will_v plain_o perceive_v that_o all_o the_o middle_n of_o the_o cone_n of_o flame_n neither_o shine_v nor_o burn_v but_o only_o the_o outward_a superficies_n thereof_o that_o be_v contiguous_a to_o the_o free_a and_o unsatiate_v air_n and_o that_o the_o middle_a part_n may_v be_v collect_v in_o the_o form_n of_o soot_n or_o very_o fine_a powder_a coal_n dust_n take_v then_o a_o piece_n of_o glass_n whether_o window-glass_n looking-glass_n plate_n or_o the_o side_n of_o a_o viol_n it_o matter_n not_o or_o which_o be_v best_a of_o all_o a_o thin_a plate_n of_o selenitis_n or_o muscovia_n talk_v and_o hold_v it_o horizontal_o in_o the_o middle_n of_o the_o flame_n so_o as_o to_o cut_v off_o the_o top_n or_o upper_a part_n of_o the_o cone_n thereof_o then_o present_o before_o it_o be_v choke_v with_o soot_n look_v down_o upon_o it_o and_o you_o shall_v plain_o see_v that_o all_o the_o middle_a part_n of_o the_o flame_n and_o the_o wick_n have_v no_o shine_a power_n or_o light_n at_o all_o nor_o be_v they_o dissolve_v by_o the_o air_n but_o remain_v in_o the_o form_n of_o soot_n but_o that_o only_o the_o superficies_n or_o outside_n of_o the_o say_a cone_n do_v burn_v shine_v and_o consume_v into_o and_o mix_v with_o the_o ambient_fw-la air._n in_o the_o same_o manner_n if_o you_o hold_v the_o glass_n or_o selenitis_n perpendicular_o and_o apply_v the_o side_n of_o it_o so_o as_o to_o cut_v the_o flame_n per_fw-mi axin_fw-mi coni_fw-la that_o the_o air_n can_v come_v to_o one_o side_n thereof_o you_o may_v plain_o perceive_v that_o the_o shine_a part_n of_o the_o flame_n be_v only_o that_o which_o be_v contiguous_a to_o and_o prey_v upon_o by_o the_o

reason_n the_o air_n can_v approach_v they_o before_o it_o be_v satiate_v at_o the_o conical_a superficies_n three_o by_o the_o dissolution_n of_o the_o steam_n of_o the_o oil_n it_o there_o meet_v with_o but_o the_o upper_a part_n of_o the_o wick_n do_v burn_v and_o shine_v if_o they_o be_v high_a enough_o into_o the_o small_a part_n of_o the_o cone_n of_o flame_n that_o the_o air_n before_o it_o be_v satiate_v can_v reach_v at_o they_o and_o if_o any_o part_n of_o the_o wick_n fall_v into_o the_o say_a conical_a and_o shine_a superficies_n of_o the_o flame_n it_o do_v both_o shine_n and_o consume_v and_o suffer_v the_o same_o dissolution_n into_o the_o air_n as_o the_o steam_n of_o the_o oil_n and_o if_o any_o part_n of_o this_o wick_n be_v without_o this_o conical_a superficies_n at_o three_o it_o be_v present_o consume_v and_o reduce_v to_o ash_n as_o by_o many_o experiment_n differ_v way_n make_v be_v very_o plain_o visible_a this_o plain_o give_v the_o cause_n why_o knot_n and_o tophus_n do_v as_o it_o be_v grow_v to_o the_o wick_n of_o the_o lamp_n like_o so_o many_o mushroom_n on_o a_o rot_a tree_n which_o as_o soon_o as_o they_o be_v remove_v out_o of_o the_o middle_n and_o dead_a part_n of_o the_o flame_n be_v immediate_o consume_v by_o and_o dissolve_v into_o the_o air_n and_o shine_v like_o a_o coal_n of_o fire_n as_o be_v indeed_o nothing_o else_o hence_o we_o may_v give_v a_o plain_a reason_n why_o upon_o apply_v any_o cool_a superficies_n very_o low_a into_o the_o flame_n of_o a_o lamp_n there_o be_v immediate_o condense_v upon_o it_o a_o great_a quantity_n of_o soot_n namely_o that_o the_o middle_a part_n of_o the_o cone_n of_o flame_n be_v nothing_o but_o a_o great_a number_n of_o oily_a steam_n ascend_v be_v not_o fire_v nor_o consume_v by_o the_o air_n till_o they_o can_v come_v to_o be_v wrought_v upon_o by_o the_o free_a and_o unsatiate_v air._n now_o if_o the_o air_n be_v so_o intercept_v that_o it_o can_v come_v at_o they_o and_o the_o steam_n be_v cool_v by_o the_o plate_n coldness_n that_o the_o air_n be_v not_o able_a to_o prey_v upon_o or_o dissolve_v they_o for_o want_n of_o a_o preparatory_a heat_n sufficient_a they_o must_v remain_v in_o the_o form_n of_o burn_a oil_n or_o lamp-black_a i_o have_v be_v somewhat_o the_o long_o and_o more_o particular_a in_o this_o description_n and_o explanation_n of_o my_o theory_n of_o the_o flame_n of_o a_o lamp_n or_o candle_n that_o so_o the_o reader_n understand_v the_o nature_n and_o cause_n thereof_o the_o more_o full_o and_o plain_o he_o may_v the_o easy_o discover_v the_o inconvenience_n that_o may_v occur_v in_o the_o burn_a heat_a shine_a duration_n etc._n etc._n thereof_o and_o the_o soon_o and_o more_o ready_o and_o scientifical_o find_v a_o cure_n and_o prevention_n of_o those_o inconvenience_n which_o he_o that_o be_v ignorant_a of_o can_v but_o hood-winked_n grope_v after_o and_o at_o best_a can_v but_o hope_v possible_o after_o long_o puzzle_v himself_o in_o vain_a attempt_n and_o blind_a trial_n nothing_o to_o the_o purpose_n he_o may_v at_o length_n stumble_v upon_o that_o which_o have_v he_o be_v enlighten_v by_o the_o true_a theory_n he_o will_v have_v ready_o go_v to_o at_o the_o first_o glance_n i_o can_v have_v further_o expatiate_v into_o the_o contemplation_n of_o this_o most_o admirable_a phenomenon_n of_o flame_n produce_v heat_n and_o light_n the_o two_o most_o spirituous_a and_o most_o potent_a agent_n in_o nature_n and_o the_o way_n of_o intend_v and_o diminish_v they_o and_o the_o use_n that_o may_v be_v make_v of_o they_o but_o that_o it_o be_v not_o my_o present_a design_n to_o annex_v a_o discourse_n on_o those_o subject_n which_o do_v more_o proper_o belong_v to_o another_o lecture_n i_o shall_v short_o publish_v i_o shall_v therefore_o at_o present_a proceed_v only_o to_o show_v some_o mechanical_a contrivance_n for_o counterpoise_v liquor_n in_o vessel_n so_o as_o to_o keep_v they_o run_v or_o supply_v a_o stream_n always_o with_o equal_a swiftness_n whatever_o quantity_n there_o be_v of_o the_o say_v fluid_a which_o as_o they_o be_v very_o

hardly_o to_o be_v perform_v without_o they_o as_o i_o shall_v hereafter_o manifest_v but_o first_o i_o will_v explain_v some_o few_o way_n by_o which_o more_o convenience_n may_v be_v obtain_v and_o more_o inconvenience_n prevent_v in_o the_o use_n of_o lamp_n for_o chemical_a mechanical_a and_o philosophical_a use_n than_o by_o this_o way_n of_o cardan_n or_o any_o other_o i_o have_v meet_v with_o for_o this_o i_o look_v upon_o as_o one_o of_o the_o tool_n to_o be_v make_v use_n of_o in_o the_o workhouse_n or_o elaboratory_n of_o nature_n without_o a_o good_a apparatus_fw-la of_o which_o
