of_o mention_v this_o last_o disease_n that_o he_o but_o borrow_v his_o encomium_n of_o mercury_n from_o begninus_n but_o however_o what_o have_v be_v relate_v have_v invite_v i_o to_o consider_v

upon_o the_o bye_n proposition_n iii_o it_o be_v likely_a that_o divers_a epidemical_a disease_n be_v in_o great_a part_n produce_v by_o subterraneal_a effluvia_fw-la i_o be_o very_a well_o aware_a that_o divers_a disease_n that_o extraordinary_o invade_v great_a number_n of_o people_n at_o the_o same_o time_n and_o be_v therefore_o by_o the_o greek_n call_v epidemical_a may_v be_v rational_o refer_v to_o manifest_a intemperateness_n of_o the_o air_n in_o point_n of_o heat_n cold_a moisture_n or_o some_o other_o obvious_a quality_n and_o therefore_o the_o proposition_n speak_v but_o of_o

improbable_a that_o divers_a of_o those_o morbific_a excess_n especial_o if_o they_o be_v sudden_a that_o be_v observe_v in_o the_o air_n may_v proceed_v from_o the_o unusual_o copious_a ascent_n of_o hurtful_a exhalation_n that_o mingle_v with_o the_o air_n and_o diffuse_v themselves_o through_o it_o we_o be_v great_a stranger_n than_o we_o common_o take_v notice_n of_o to_o the_o subterraneat_a part_n of_o the_o globe_n we_o inhabit_v and_o if_o i_o have_v leisure_n and_o think_v it_o necessary_a i_o can_v show_v that_o there_o be_v a_o great_a many_o odd_a and_o surprise_v thing_n to_o be_v meet_v with_o in_o the_o structure_n and_o disposition_n even_o of_o those_o part_n of_o the_o earth_n that_o lie_v but_o a_o little_a way_n beneath_o the_o surface_n of_o it_o and_o partly_o have_v be_v and_o partly_o may_v easy_o enough_o be_v actual_o penetrate_v by_o the_o industrious_a labour_n of_o man_n and_o as_o for_o the_o deep_a subterraneal_a region_n we_o be_v so_o much_o more_o unacquainted_a with_o they_o that_o we_o be_v scarce_o fit_a so_o much_o as_o to_o conjecture_v how_o far_o they_o extend_v or_o what_o kind_n of_o material_n they_o contain_v and_o what_o be_v the_o gross_a and_o if_o i_o may_v so_o speak_v the_o mechanical_a fabric_n of_o the_o great_a mass_n whether_o solid_a or_o fluid_a they_o consist_v of_o and_o lest_o of_o all_o can_v we_o determine_v what_o motion_n whether_o periodical_a or_o other_o these_o mass_n or_o other_o portion_n of_o deep_o lodge_v matter_n may_v have_v on_o such_o ground_n as_o these_o i_o conceive_v it_z possible_a that_o among_o the_o many_o and_o various_a effluviate_a body_n that_o the_o terrestrial_a globe_n may_v conceal_v in_o its_o bowel_n there_o may_v be_v some_o who_o reek_n ascend_v plentiful_o into_o the_o air_n may_v occasion_v in_o it_o a_o excess_n of_o heat_n cold_a moisture_n thickness_n or_o some_o other_o manifest_a quality_n so_o that_o sometime_o not_o to_o say_v many_o time_n even_o those_o manifest_a intemperateness_n of_o the_o air_n to_o which_o a_o epidemical_a disease_n be_v wont_a to_o be_v whole_o impute_v though_o perhaps_o not_o very_o just_o may_v in_o part_n proceed_v from_o subterraneal_a body_n for_o i_o elsewhere_o show_v that_o these_o by_o their_o conflict_n or_o mutual_a action_n on_o one_o another_o may_v excite_v great_a and_o sudden_a heat_n and_o on_o that_o account_n send_v up_o such_o copious_a steam_n into_o the_o atmosphere_n as_o may_v produce_v there_o sudden_a and_o excessive_a heat_n lightning_n thunder_n etc._n etc._n and_o i_o shall_v now_o add_v what_o perhaps_o will_v appear_v somewhat_o strange_a that_o i_o think_v sudden_a and_o unseasonable_a refrigeration_n of_o the_o air_n may_v proceed_v from_o the_o action_n of_o subterraneal_a body_n upon_o one_o another_o for_o trial_n purposely_o make_v have_v inform_v i_o that_o there_o be_v certain_a mineral_n whereof_o some_o may_v be_v employ_v in_o their_o crude_a

by_o their_o reaction_n a_o intense_a degree_n of_o cold_a not_o only_o as_o to_o sense_n but_o when_o examine_v by_o a_o seal_a weatherglass_n the_o change_n of_o the_o air_n that_o produce_v epidemical_a disease_n be_v sometime_o so_o great_a and_o sudden_a that_o they_o can_v in_o my_o opinion_n with_o probability_n be_v impute_v to_o the_o action_n of_o the_o sun_n or_o the_o moon_n which_o be_v cause_n that_o act_n in_o too_o general_a and_o too_o uniform_a a_o way_n to_o have_v those_o particular_a and_o anomalous_a effect_n attribute_v to_o they_o as_o probable_o as_o they_o may_v be_v to_o subterraneal_a body_n that_o often_o act_v with_o more_o suddenness_n and_o impetuosity_n and_o without_o any_o regularity_n at_o least_o that_o be_v know_v to_o we_o the_o

and_o now_o and_o then_o i_o have_v observe_v in_o the_o same_o month_n and_o day_n at_o no_o great_a distance_n from_o one_o another_o that_o the_o wether_n have_v be_v sultry_a hot_a and_o have_v also_o produce_v a_o great_a snow_n we_o have_v see_v summer_n like_o that_o which_o be_v remember_v for_o the_o siege_n of_o colchester_n that_o for_o almost_o the_o whole_a season_n where_o more_o

be_v either_o last_a or_o very_a intense_a but_o instance_n of_o this_o kind_n be_v so_o obvious_a to_o those_o that_o be_v at_o all_o heedful_a observer_n that_o i_o may_v safe_o pass_v they_o by_o and_o inculcate_v that_o the_o sun_n be_v in_o the_o same_o sign_n at_o the_o same_o time_n of_o the_o year_n it_o do_v not_o appear_v how_o he_o shall_v produce_v so_o great_a a_o disparity_n of_o

therefore_o i_o do_v not_o so_o much_o wonder_n that_o many_o learned_a writer_n fly_v to_o astrology_n for_o a_o account_n of_o these_o irregular_a phaenomena_n and_o ascribe_v they_o to_o the_o

astrology_n i_o shall_v not_o now_o stay_v to_o discuss_v the_o question_n whether_o the_o star_n have_v any_o influence_n distinct_a from_o their_o light_n and_o heat_n because_o my_o opinion_n about_o it_o be_v somewhat_o peculiar_a i_o have_v discourse_v of_o it_o in_o a_o paper_n by_o itself_o but_o this_o i_o shall_v now_o say_v that_o the_o fix_a star_n be_v but_o general_a and_o if_o i_o may_v so_o speak_v indefinite_a agent_n almost_o unimaginable_o remote_a from_o we_o it_o be_v nothing_o near_o so_o likely_a that_o such_o effect_n as_o beside_o that_o they_o happen_v very_o sudden_o and_o irregular_o be_v oftentimes_o confine_v to_o a_o town_n or_o some_o other_o narrow_a compass_n shall_v be_v produce_v by_o certain_a star_n as_o that_o they_o shall_v be_v so_o by_o

i_o have_v know_v a_o great_a cold_a in_o a_o
vegetable_n enable_v a_o little_a sour_a dough_n to_o extend_v itself_o through_o the_o whole_a mass_n or_o such_o as_o when_o a_o apple_n or_o pear_n be_v bruise_v in_o one_o part_n make_v the_o

and_o sometime_o colour_n and_o odour_n and_o in_o short_a such_o a_o state_n as_o by_o one_o word_n we_o call_v maturity_n or_o ripeness_n and_o so_o some_o metalline_a oar_n and_o some_o mineral_n earth_n themselves_o have_v be_v observe_v by_o mineralogist_n to_o acquire_v in_o tract_n of_o time_n such_o a_o change_n as_o to_o afford_v some_o metal_n or_o other_o body_n which_o either_o it_o

of_o what_o lie_v beneath_o that_o comparative_o very_o thin_a crust_n or_o scurf_n if_o i_o may_v so_o call_v it_o that_o humane_a industry_n have_v be_v hitherto_o confine_v to_o and_o upon_o this_o account_n i_o do_v not_o think_v it_o absurd_a to_o suspect_v that_o from_o the_o low_a subterraneal_a region_n there_o may_v be_v either_o continual_o or_o periodical_o emit_v into_o the_o region_n of_o mine_n if_o i_o may_v so_o call_v it_o great_a store_n and_o variety_n of_o mineral_n exhalation_n which_o may_v continual_o repair_v the_o loss_n of_o those_o that_o from_o time_n to_o time_n ascend_v out_o of_o the_o fossile_n region_n as_o i_o may_v also_o call_v that_o of_o mine_n into_o the_o atmosphere_n but_o the_o thing_n i_o can_v allege_v to_o countenance_v this_o conjecture_n must_v not_o be_v insist_v on_o in_o this_o place_n therefore_o i_o proceed_v to_o consider_v 3._o that_o body_n so_o heavy_a and_o consequent_o so_o abundant_a in_o part_n of_o solid_a matter_n crowd_v together_o as_o mineral_n and_o other_o fossiles_n be_v wont_a to_o be_v may_v well_o be_v suppose_v capable_a without_o destructive_o waste_v themselves_o to_o emit_v store_n of_o such_o
