the_o answer_n i_o receive_v from_o a_o very_a ingenious_a gentleman_n who_o live_v among_o mine_n and_o be_v not_o a_o little_a concern_v in_o some_o of_o they_o for_o have_v inquire_v of_o he_o what_o he_o have_v observe_v about_o the_o lie_a or_o not_o lie_v of_o the_o snow_n on_o the_o mineral_n soil_v near_o the_o place_n of_o his_o residence_n he_o reply_v that_o in_o some_o of_o they_o he_o do_v not_o take_v notice_n of_o any_o peculiar_a indisposition_n to_o let_v the_o ice_n and_o snow_n continue_v on_o they_o which_o i_o conceive_v may_v proceed_v either_o from_o the_o want_n of_o such_o mineral_n in_o the_o subjacent_a part_n as_o be_v then_o in_o the_o state_n of_o incalescence_n or_o else_o from_o this_o that_o according_a to_o what_o we_o have_v elsewhere_o observe_v about_o the_o snow_n on_o aetna_n the_o direct_a ascension_n of_o the_o hot_a steam_n be_v hinder_v by_o some_o layer_n of_o rock_n or_o other_o stone_n through_o which_o the_o steam_n can_v not_o penetrate_v or_o can_v do_v it_o but_o so_o slow_o as_o to_o loose_v their_o actual_a warmth_n by_o the_o way_n but_o this_o gentleman_n add_v that_o in_o other_o place_n near_o that_o of_o his_o abode_n and_o such_o as_o he_o know_v to_o have_v minerall-vein_n beneath_o they_o he_o observe_v that_o the_o snow_n nor_o the_o ice_n will_v scarce_o continue_v at_o all_o upon_o the_o surface_n of_o the_o ground_n even_o in_o a_o extraordinary_o cold_a winter_n it_o will_v be_v a_o considerable_a instance_n to_o our_o purpose_n if_o it_o be_v indeed_o true_a which_o some_o learned_a man_n have_v write_v that_o near_o the_o gold-mine_n in_o hungary_n the_o leaf_n of_o the_o tree_n especial_o those_o that_o respct_v the_o ground_n be_v oftentimes_o find_v ennoble_v with_o a_o golden-colour_n from_o the_o metalline_a exhalation_n of_o the_o gold-mine_n which_o one_o will_v think_v must_v by_o reason_n of_o their_o ponderousnesse_n need_v a_o considerable_a heat_n to_o elevate_v they_o especial_o into_o the_o open_a air._n but_o though_o doubt_v of_o this_o relation_n as_o not_o make_v by_o mineralist_n or_o accurate_a observer_n i_o inquire_v about_o it_o of_o a_o person_n who_o curiosity_n carry_v he_o purposely_o to_o visit_v those_o mine_n i_o be_v answer_v that_o he_o can_v not_o be_v a_o witness_n to_o the_o truth_n of_o the_o observation_n yet_o he_o

such_o magazine_n of_o heat_n which_o probable_o may_v be_v want_v in_o many_o place_n of_o the_o earth_n i_o shall_v ready_o confess_v that_o as_o i_o first_o make_v this_o objection_n to_o myself_o so_o i_o do_v not_o yet_o discern_v it_o to_o be_v unreasonable_a and_o that_o for_o aught_o i_o know_v if_o man_n have_v occasion_n to_o dig_v as_o deep_a and_o be_v as_o far_o conversant_a in_o many_o other_o low_a place_n of_o the_o earth_n where_o there_o be_v no_o sign_n of_o mineral_n as_o they_o have_v do_v where_o the_o hope_n of_o actual_a discovery_n of_o vein_n of_o metal_n and_o
