tell_v i_o that_o in_o a_o mine_n who_o descent_n do_v not_o much_o exceed_v a_o hundred_o fathom_n the_o cold_a region_n be_v extend_v near_o to_o the_o bottom_n of_o it_o and_o this_o relation_n be_v agreeable_a with_o what_o morinus_n affirm_v viz._n that_o the_o cold_a region_n in_o a_o hungarian_a mine_n which_o he_o visit_v be_v extend_v 80_o fathom_n after_o which_o the_o heat_n sensible_o increase_v the_o low_a he_o descend_v and_o the_o same_o author_n affirm_v that_o beside_o the_o different_a temper_n of_o those_o region_n there_o be_v likewise_o observe_v a_o different_a degree_n of_o heat_n in_o the_o hot_a region_n correspondent_a to_o the_o different_a season_n of_o the_o year_n viz._n winter_n and_o summer_n i._n the_o temperature_n of_o subterraneal_a region_n consider_v under_o certain_a proposition_n prop._n i._n these_o thing_n premise_v in_o general_n i_o shall_v now_o proceed_v to_o consider_v the_o particular_a region_n of_o the_o earth_n in_o the_o four_o follow_a proposition_n proposition_n i._n the_o bound_n as_o well_o as_o temperature_n of_o the_o first_o region_n be_v very_o different_a the_o reason_n of_o both_o part_n of_o which_o proposition_n be_v plain_a since_o the_o sun_n beam_n must_v not_o only_o penetrate_v deep_a in_o the_o summer_n than_o the_o winter_n but_o also_o because_o the_o solidity_n or_o porousness_n of_o several_a part_n of_o the_o earth_n may_v dispose_v the_o soil_n to_o heat_n or_o coldness_n but_o to_o proceed_v it_o be_v remarkable_a that_o the_o uppermost_a region_n be_v much_o more_o temperate_a because_o both_o the_o violent_a impression_n of_o sun_n beam_n and_o rugged_a wind_n be_v keep_v off_o by_o the_o side_n of_o those_o subterraneal_a cavity_n and_o that_o the_o power_n of_o the_o sun_n beam_n be_v much_o weaken_a by_o those_o side_n be_v plain_a since_o by_o such_o like_a mean_n the_o heat_n of_o the_o sun_n may_v be_v so_o break_v as_o to_o preserve_v ice_n from_o thaw_v all_o summer_n and_o not_o only_o so_o but_o if_o those_o subterraneal_a cavity_n be_v sufficient_o guard_v with_o a_o cover_n of_o brick_n well_o clay_v over_o and_o be_v by_o that_o mean_n preserve_v from_o any_o intercourse_n with_o the_o external_n air_n it_o may_v be_v preserve_v without_o dig_v deep_a into_o the_o ground_n as_o be_v observe_v in_o the_o south_n part_n of_o france_n so_o that_o though_o the_o coldness_n of_o subterraneal_a cavity_n may_v conduce_v yet_o it_o be_v not_o altogether_o requisite_a to_o preserve_v ice_n from_o a_o thaw_v but_o the_o subterraneal_a region_n be_v not_o only_o preserve_v from_o excessive_a heat_n by_o prevent_v the_o intercourse_n of_o the_o internal_a and_o the_o external_n air_n but_o may_v be_v considerable_o lessen_v in_o such_o cavity_n as_o be_v considerable_o expose_v to_o the_o open_a air_n as_o i_o myself_o have_v observe_v in_o a_o iron_n mine_v not_o above_o twelve_o foot_n deep_a as_o as_o it_o be_v to_o be_v observe_v that_o this_o cold_a region_n of_o the_o air_n be_v not_o apt_a to_o be_v influence_v by_o external_a heat_n in_o the_o summer_n so_o neither_o be_v the_o hot_a region_n subject_a to_o be_v alter_v much_o by_o the_o external_a cold_a in_o winter_n which_o appear_v from_o the_o smoke_n of_o some_o spring_n in_o winter_n which_o be_v supply_v with_o water_n which_o have_v run_v a_o considerable_a depth_n in_o the_o ground_n or_o pass_v through_o some_o earth_n that_o be_v fit_o dispose_v to_o warm_v it_o in_o its_o passage_n but_o further_a that_o winter_n cold_a be_v much_o
