i_o need_v not_o spend_v time_n about_o what_o he_o teach_v de_fw-fr modo_fw-la to_o examine_v then_o only_o the_o first_o of_o the_o above_o mention_v particular_n i_o shall_v begin_v with_o observe_v that_o his_o story_n of_o the_o damp_n to_o be_v meet_v with_o in_o mine_n be_v more_o large_o set_v down_o by_o mr._n hobbs_n in_o that_o chapter_n of_o his_o element_n of_o philosophy_n where_o he_o treat_v of_o gravity_n in_o which_o place_n he_o seem_v to_o mention_v it_o to_o use_v his_o own_o expression_n as_o a_o story_n of_o doubtful_a credit_n which_o it_o be_v not_o like_a he_o will_v have_v do_v if_o have_v then_o see_v it_o which_o i_o mention_v not_o that_o i_o deny_v the_o story_n for_o the_o main_a nor_o that_o i_o will_v bring_v mr._n hobbs_n into_o a_o suspicion_n of_o relate_v thing_n untrue_a as_o matter_n of_o fact_n his_o enemy_n themselves_o have_v not_o accuse_v he_o of_o such_o a_o meanness_n but_o because_o if_o he_o have_v not_o since_o observe_v the_o thing_n himself_o there_o may_v easy_o be_v a_o mistake_n in_o some_o of_o the_o circumstance_n as_o for_o instance_n the_o number_n of_o minute_n wherein_o the_o thick_a air_n choke_v the_o fire_n and_o it_o be_v upon_o that_o circumstance_n that_o the_o validity_n of_o what_o he_o deduce_v from_o the_o observation_n chief_o depend_v but_o however_o the_o matter_n fare_v with_o these_o subterraneal_a damp_n we_o have_v already_o prove_v by_o several_a of_o the_o experiment_n of_o our_o engine_n that_o in_o the_o exhaust_a receiver_n there_o be_v no_o such_o motion_n of_o the_o air_n as_o be_v here_o suppose_a and_o it_o may_v be_v sufficient_o prove_v that_o whatever_o remain_v in_o the_o receiver_n be_v not_o such_o a_o substance_n as_o mr._n hobbs_n will_v have_v it_o for_o that_o he_o here_o tell_v we_o be_v of_o a_o consistence_n betwixt_o air_n and_o water_n and_o in_o the_o above_o cite_a place_n of_o his_o element_n he_o say_v that_o it_o be_v not_o much_o light_a than_o water_n but_o by_o the_o magdeburgick_a experiment_n we_o have_v already_o have_v occasion_n to_o mention_v two_o or_o three_o time_n it_o be_v evident_a that_o the_o receiver_n by_o be_v exhaust_v of_o common_a air_n be_v so_o far_o from_o grow_v heavy_a much_o less_o so_o much_o heavy_a as_o it_o must_v if_o it_o be_v fill_v with_o a_o substance_n not_o much_o light_a than_o water_n that_o it_o lose_v above_o a_o ounce_n of_o its_o former_a weight_n and_o to_o this_o agree_v what_o we_o see_v happen_v in_o aeolipile_n that_o grow_v light_a when_o the_o air_n be_v expel_v beside_o if_o the_o receiver_n be_v in_o our_o present_a case_n fill_v with_o a_o substance_n who_o consistence_n be_v so_o much_o near_a that_o of_o water_n than_o be_v our_o common_a air_n as_o mr._n hobbs_n will_v have_v it_o how_o chance_v a_o pendulum_n shall_v not_o move_v very_o sensible_o slow_a in_o it_o when_o in_o water_n the_o diadrome_n be_v so_o exceed_o much_o more_o slow_a and_o the_o break_n of_o a_o hermetically-sealed_a bubble_n in_o our_o receiver_n outward_o when_o the_o air_n be_v much_o exhaust_v and_o not_o before_o together_o with_o divers_a other_o experiment_n that_o may_v be_v easy_o apply_v to_o this_o purpose_n in_o our_o epistle_n do_v sufficient_o evince_v that_o it_o be_v not_o a_o thick_a and_o far_o heavy_a air_n but_o a_o more_o yield_v and_o light_a that_o remain_v after_o pump_v in_o the_o cavity_n of_o our_o receiver_n and_o thus_o much_o as_o to_o mr._n hobbs_n discourse_n upon_o our_o experiment_n but_o as_o for_o the_o thing_n itself_o it_o appear_v that_o when_o i_o relate_v it_o i_o think_v it_o may_v admit_v a_o further_a enquiry_n and_o indeed_o there_o may_v be_v so_o many_o way_n of_o extinguish_v fire_n as_o we_o see_v that_o the_o flame_n of_o a_o candle_n may_v be_v blow_v out_o by_o the_o wind_n or_o quench_v in_o water_n or_o put_v out_o by_o the_o compression_n of_o a_o pair_n of_o snuffer_n or_o suffocate_v for_o want_n of_o air_n to_o receive_v its_o fuliginous_a steam_n or_o if_o that_o be_v a_o different_a way_n stifle_v by_o the_o thick_a exhalation_n of_o deep_a mine_n or_o of_o new_a wine_n that_o as_o it_o be_v not_o in_o all_o case_n so_o easy_a to_o assign_v the_o true_a cause_n of_o the_o extinction_n of_o fire_n so_o it_o be_v unsafe_a to_o conclude_v with_o mr._n hobbs_n that_o because_o a_o candle_n or_o a_o live_a coal_n may_v a_o great_a way_n under_o ground_n be_v extinguish_v by_o a_o thick_a damp_n therefore_o the_o effect_n must_v proceed_v from_o the_o like_a
