contract_v it_o and_o more_o abundent_o increase_v its_o weight_n why_o the_o mercury_n fall_v low_a in_o great_a wind_n the_o reason_n of_o this_o may_v be_v for_o that_o these_o great_a storm_n force_v out_o violent_o that_o air_n that_o stagnat_n in_o those_o place_n in_o which_o they_o blow_v and_o that_o with_o so_o great_a a_o violence_n that_o the_o adjacent_a air_n can_v come_v in_o

violent_a may_v take_v off_o much_o of_o the_o perpendicular_a pressure_n of_o the_o air_n and_o that_o may_v suffer_v the_o quicksilver_n to_o sink_v down_o so_o very_o low_o the_o reason_n why_o it_o rain_n very_o seldom_o in_o great_a wind_n though_o the_o quicksilver_n be_v low_a this_o be_v because_o though_o the_o air_n be_v then_o too_o light_a to_o support_v almost_o any_o kind_n of_o

agitate_a by_o shake_v it_o will_v then_o swim_v so_o long_o as_o that_o motion_n continue_v so_o here_o the_o agitation_n of_o the_o air_n by_o strong_a wind_n keep_v those_o vapour_n from_o descend_v which_o otherwise_o will_v fall_v by_o reason_n of_o the_o air_n lightness_n and_o this_o be_v the_o reason_n why_o when_o there_o be_v rain_n in_o the_o air_n it_o general_o hold_v up_o till_o these_o wind_n cease_v and_o then_o it_o fall_v down_o why_o southern_a wind_n sometime_o produce_v rain_n though_o the_o quicksilver_n rise_v and_o northern_a or_o eastern_a fair_a though_o the_o quicksilver_n fall_v to_o understand_v this_o consider_v that_o watery_a particle_n be_v rarify_v by_o the_o diversity_n of_o the_o celestial_a influence_n into_o body_n of_o divers_a dimension_n and_o the_o more_o intense_a that_o heat_n be_v that_o rarefy_v by_o so_o much_o the_o large_a will_v those_o aquaous_a particle_n be_v this_o be_v plain_a in_o wet_a linen_n present_v

have_v it_o be_v hang_v up_o to_o dry_a in_o a_o less_o intense_a heat_n it_o will_v have_v become_v dry_a by_o a_o more_o minute_n and_o insensible_a evaporation_n now_o it_o be_v plain_a that_o what_o rain_n come_v to_o we_o from_o the_o south_n do_v arise_v in_o part_n more_o hot_a than_o we_o and_o by_o consequence_n be_v rarification_n of_o the_o large_a size_n and_o such_o as_o be_v too_o heavy_a to_o be_v suspend_v by_o that_o weight_n of_o air_n that_o be_v usual_o produce_v by_o wind_n from_o that_o quarter_n whereas_o on_o the_o contrary_a those_o vapour_n that_o be_v raise_v in_o cold_a country_n and_o bring_v to_o we_o by_o northern_a or_o easterly_a wind_n be_v much_o more_o fine_a and_o light_n and_o by_o consequence_n be_v uncapable_a of_o fall_v down_o in_o our_o climate_n though_o the_o air_n shall_v grow_v light_a than_o usual_a for_o though_o this_o lightness_n may_v be_v remarkable_a yet_o it_o may_v be_v still_o heavy_a than_o those_o light_a vapour_n

2_o or_o 3_o day_n after_o the_o quicksilver_n rise_v before_o fair_a wether_n come_v it_o argue_v that_o the_o celestial_a influence_n do_v not_o concur_v with_o other_o natural_a cause_n at_o that_o

and_o that_o be_v again_o condense_v it_o follow_v that_o the_o air_n must_v needs_o then_o be_v very_o weighty_a and_o so_o buoy_v up_o the_o quicksilver_n very_o high_a why_o rise_v yet_o high_a in_o frosty_a wether_n when_o the_o quicksilver_n be_v already_o very_o high_a foreshow_v snow_n the_o reason_n be_v because_o snow_n when_o form_v above_o be_v by_o its_o extreme_a coldness_n
