spread_v themselves_o every_o way_n upon_o the_o earth_n superficies_n as_o i_o have_v show_v at_o the_o 8_o article_n of_o the_o 21th_o chapter_n 5_o we_o perceive_v a_o body_n to_o be_v hard_a from_o this_o that_o when_o touch_v it_o we_o will_v thrust_v forward_o that_o part_n of_o the_o same_o which_o we_o touch_v we_o can_v do_v it_o otherwise_o then_o by_o thrust_v forward_o the_o whole_a body_n we_o may_v indeed_o easy_o and_o sensible_o thrust_v forward_o any_o particle_n of_o the_o air_n or_o water_n which_o we_o touch_v whilst_o yet_o the_o rest_n of_o its_o part_n remain_v to_o sense_n unmoved_a but_o we_o can_v do_v so_o to_o any_o part_n of_o a_o stone_n wherefore_o i_o define_v a_o hard_a body_n to_o be_v that_o whereof_o no_o part_n can_v be_v sensible_o move_v unless_o the_o whole_a be_v move_v whatsoever_o therefore_o be_v soft_a or_o fluid_a the_o same_o can_v never_o be_v make_v hard_o but_o by_o such_o motion_n as_o make_v many_o of_o the_o part_n together_o stop_v the_o motion_n of_o some_o one_o part_n by_o resist_v the_o same_o 6_o these_o thing_n premise_v i_o shall_v show_v a_o possible_a cause_n why_o there_o be_v great_a cold_a near_o the_o pole_n of_o the_o earth_n then_o further_o from_o they_o the_o motion_n of_o the_o sun_n between_o the_o tropic_n drive_v the_o air_n towards_o that_o part_n of_o the_o earth_n superficies_n which_o be_v perpendicular_o under_o it_o make_v it_o spread_v itself_o every_o way_n and_o the_o velocity_n of_o this_o expansion_n of_o the_o air_n grow_v great_a and_o great_a as_o the_o superficies_n of_o the_o earth_n come_v to_o be_v more_o and_o more_o straighten_v that_o be_v to_o say_v as_o the_o circle_n which_o be_v parallel_v to_o the_o aequator_fw-la come_v to_o be_v less_o and_o less_o wherefore_o this_o expansive_a motion_n of_o the_o air_n drive_v before_o it_o the_o part_n of_o the_o air_n which_o be_v in_o its_o way_n continual_o towards_o the_o pole_n more_o and_o more_o strong_o as_o its_o force_n come_v to_o be_v more_o and_o more_o unite_a that_o be_v to_o say_v as_o the_o circle_n which_o be_v parallel_v to_o the_o aequator_fw-la be_v less_o and_o less_o that_o be_v so_o much_o the_o more_o by_o how_o much_o they_o be_v near_o to_o the_o pole_n of_o the_o earth_n in_o those_o place_n therefore_o which_o be_v near_a to_o the_o pole_n there_o be_v great_a cold_a then_o in_o those_o which_o be_v more_o remote_a from_o they_o now_o this_o expansion_n of_o the_o air_n upon_o the_o superficies_n of_o the_o earth_n from_o east_n to_o west_n do_v by_o reason_n of_o the_o sun_n perpetual_a accession_n to_o the_o place_n which_o be_v successive_o under_o it_o make_v it_o cold_a at_o the_o time_n of_o the_o sun_n rise_v and_o set_v but_o as_o the_o sun_n come_v to_o be_v continual_o more_o and_o more_o perpendicular_a to_o those_o cool_v place_n so_o by_o the_o heat_n which_o be_v generate_v by_o the_o superven_a simple_a motion_n of_o the_o sun_n that_o cold_a be_v again_o remit_v and_o can_v never_o be_v great_a because_o the_o action_n by_o the_o which_o it_o be_v generate_v be_v not_o permanent_a wherefore_o i_o have_v render_v a_o possible_a cause_n of_o cold_a in_o those_o place_n that_o be_v near_o the_o pole_n or_o where_o the_o obliquity_n of_o the_o sun_n be_v great_a 7_o how_o water_n may_v be_v congeal_v by_o cold_a may_v be_v explain_v in_o this_o manner_n let_v a_o in_o the_o first_o figure_n represent_v the_o sun_n and_o b_o the_o earth_n a_o will_v therefore_o be_v much_o great_a than_o b._n let_v of_o be_v in_o the_o plain_a of_o the_o equinoctial_a to_o which_o let_v gh_a ik_fw-mi and_o lc_n be_v parallel_n last_o let_v c_o and_o d_o be_v the_o pole_n of_o the_o earth_n the_o air_n therefore_o by_o its_o action_n in_o those_o parallel_n will_v rake_v the_o superficies_n of_o the_o earth_n and_o that_o with_o motion_n so_o much_o the_o strong_a by_o how_o much_o the_o parallel_a circle_n towards_o the_o pole_n grow_v less_o and_o less_o from_o whence_o must_v arise_v a_o wind_n which_o will_v force_v together_o the_o uppermost_a part_n of_o the_o water_n and_o withal_o raise_v they_o a_o little_a weaken_v their_o endeavour_n towards_o the_o centre_n of_o the_o earth_n and_o from_o their_o endeavour_n towards_o the_o centre_n of_o the_o earth_n join_v with_o the_o endeavour_n of_o the_o say_a wind_n the_o uppermost_a part_n of_o the_o water_n will_v be_v press_v together_o and_o coagulate_v that_o be_v to_o say_v the_o top_n of_o the_o water_n will_v be_v skin_v over_o and_o harden_v and_o so_o again_o the_o water_n next_o the_o top_n will_v be_v harden_v in_o the_o same_o manner_n till_o at_o length_n the_o ice_n be_v thick_a and_o this_o ice_n be_v now_o compact_v of_o little_a hard_a body_n must_v also_o contain_v many_o particle_n of_o air_n receive_v into_o it_o as_o river_n and_o sea_n so_o also_o in_o the_o same_o manner_n may_v the_o cloud_n be_v freeze_v for_o when_o by_o the_o ascend_a and_o descend_v of_o several_a cloud_n at_o the_o same_o time_n the_o air_n intercept_v between_o they_o be_v by_o compression_n force_v out_o it_o rake_n &_o by_o little_a &_o little_o harden_v they_o and_o though_o those_o small_a drop_n which_o usual_o make_v cloud_n be_v not_o yet_o unite_v into_o great_a body_n yet_o the_o same_o wind_n will_v be_v make_v &_o by_o it_o as_o water_n be_v congeal_v into_o ice_n so_o will_v vapour_n in_o the_o same_o manner_n be_v congeal_v into_o snow_n from_o the_o same_o cause_n it_o be_v that_o ice_n may_v be_v make_v by_o art_n and_o that_o not_o far_o from_o the_o fire_n for_o it_o be_v do_v by_o the_o mingle_n of_o snow_n and_o salt_n together_o and_o by_o bury_v in_o it_o a_o small_a vessel_n full_a of_o water_n now_o while_o the_o snow_n and_o salt_n which_o have_v in_o they_o a_o great_a deal_n of_o air_n be_v melt_v the_o air_n which_o be_v press_v out_o every_o way_n in_o wind_n rake_n the_o side_n of_o the_o vessel_n and_o as_o the_o wind_n by_o its_o motion_n rake_n the_o vessel_n so_o the_o vessel_n by_o the_o same_o motion_n and_o action_n congeles_fw-la the_o water_n within_o it_o we_o find_v by_o experience_n that_o cold_a be_v always_o more_o remiss_a in_o place_n where_o it_o rain_v or_o where_o the_o weather_n be_v cloudy_a thing_n be_v alike_o in_o all_o other_o respect_n then_o where_o the_o air_n be_v clear_a and_o this_o agree_v very_o well_o with_o what_o i_o have_v say_v before_o for_o in_o clear_a weather_n the_o course_n of_o the_o wind_n which_o as_o i_o say_v even_o now_o rake_n the_o superficies_n of_o the_o earth_n as_o it_o be_v free_a from_o all_o interruption_n so_o also_o it_o be_v very_o strong_a but_o when_o small_a drop_n of_o water_n be_v either_o rise_n or_o fall_v that_o wind_n be_v repel_v break_v and_o dissipate_v by_o they_o and_o the_o less_o the_o wind_n be_v the_o less_o be_v the_o cold._n we_o find_v also_o by_o experience_n that_o in_o deep_a well_n the_o water_n freeze_v not_o so_o much_o as_o it_o do_v upon_o the_o superficies_n of_o the_o earth_n for_o the_o wind_n by_o which_o ice_n be_v make_v enter_v into_o the_o earth_n by_o reason_n of_o the_o laxity_n of_o its_o part_n more_o or_o less_o lose_v some_o of_o its_o force_n though_o not_o much_o so_o that_o if_o the_o well_o be_v not_o deep_a it_o will_v freeze_v whereas_o if_o it_o be_v so_o deep_a as_o that_o the_o wind_n which_o cause_v cold_a can_v reach_v it_o it_o will_v not_o freeze_v we_o find_v moreover_o by_o experience_n that_o ice_n be_v light_a than_o water_n the_o cause_n whereof_o be_v manifest_a from_o that_o which_o i_o have_v already_o show_v namely_o that_o air_n be_v receive_v in_o and_o mingle_v with_o the_o particle_n of_o the_o water_n while_o it_o be_v in_o congeling_n 8_o we_o have_v see_v one_o way_n of_o make_v thing_n hard_a namely_o by_o congelation_n another_o way_n be_v thus_o have_v already_o suppose_v that_o innumerable_a atom_n some_o hard_a than_o other_o and_o that_o have_v several_a simple_a motion_n of_o their_o own_o be_v intermingle_v with_o the_o aethereal_a substance_n
