if_o you_o take_v away_o of_o the_o heavy_a body_n till_o they_o agree_v in_o weight_n with_o the_o light_a they_o will_v take_v up_o and_o fill_v different_a proportion_n and_o part_n of_o the_o

let_v we_o conceive_v that_o all_o the_o quantity_n of_o the_o world_n be_v in_o one_o uniform_a substance_n than_o the_o whole_a universe_n will_v be_v in_o one_o and_o the_o same_o degree_n of_o

motion_n which_o light_n be_v able_a to_o give_v unto_o the_o air_n must_v needs_o be_v a_o swell_a of_o that_o moist_a element_n perpendicular_o round_a about_o the_o earth_n for_o the_o ray_n descendent_a and_o the_o ray_n reflectent_n fly_v with_o so_o great_a a_o speed_n that_o the_o air_n between_o they_o can_v not_o take_v a_o formal_a ply_v any_o way_n before_o the_o beam_n of_o light_n be_v on_o both_o side_n of_o it_o it_o follow_v that_o according_a to_o the_o nature_n of_o humid_a thing_n it_o must_v first_o only_o swell_v for_o that_o be_v the_o begin_n of_o motion_n in_o they_o when_o heat_n enter_v into_o they_o and_o work_v upon_o they_o and_o thus_o he_o may_v confident_o resolve_v himself_o that_o the_o first_o motion_n which_o light_n cause_v in_o the_o

he_o will_v likewise_o plain_o see_v that_o if_o there_o be_v any_o other_o little_a dense_a body_n float_v in_o the_o air_n they_o must_v likewise_o mount_v a_o little_a through_o this_o swell_a and_o rise_v of_o the_o air_n but_o that_o mount_a will_v be_v no_o more_o than_o the_o immediate_a part_n of_o the_o air_n themselves_o do_v move_v because_o this_o motion_n be_v not_o by_o way_n of_o impulse_n or_o stroke_n that_o the_o air_n give_v those_o denser_n body_n but_o by_o way_n of_o contain_v they_o in_o it_o and_o carry_v they_o with_o it_o â—o_z that_o it_o give_v they_o no_o more_o celerity_n then_o to_o make_v they_o go_v with_o itself_o and_o as_o part_n of_o itself_o then_o let_v he_o consider_v that_o light_n or_o fire_n by_o much_o beat_n upon_o the_o earth_n divide_v some_o little_a part_n of_o it_o from_o other_o whereof_o if_o any_o do_v become_v so_o small_a and_o tractable_a as_o not_o to_o exceed_v the_o strength_n which_o the_o ray_n have_v to_o manage_v they_o the_o return_a ray_n will_v at_o their_o go_v back_o carry_v away_o with_o they_o or_o drive_v before_o they_o such_o little_a atom_n as_o they_o have_v make_v or_o meet_v with_o and_o so_o fill_v the_o air_n with_o little_a body_n cut_v out_o of_o the_o earth_n after_o this_o let_v he_o consider_v that_o when_o light_n carry_v up_o a_o atom_n with_o it_o the_o light_n and_o the_o

that_o so_o then_o the_o stroke_n of_o the_o atom_n be_v more_o efficacious_a upon_o water_n then_o upon_o cork_n because_o the_o density_n of_o water_n be_v great_a than_o the_o density_n of_o cork_n consider_v the_o abundance_n of_o air_n that_o be_v harbour_v in_o the_o large_a pore_n of_o it_o it_o follow_v that_o the_o atom_n will_v make_v the_o water_n go_v down_o more_o forcible_o than_o

have_v more_o force_n upon_o the_o water_n then_o upon_o the_o cork_n they_o make_v the_o water_n sink_v and_o slide_v under_o it_o first_o a_o little_a thin_a plate_n of_o water_n and_o then_o a_o

from_o a_o dryness_n peculiar_a to_o it_o that_o comprehend_v and_o fix_v the_o humidity_n of_o it_o for_o by_o the_o first_o they_o be_v render_v capable_a of_o be_v drive_v into_o any_o figure_n

because_o these_o two_o condition_n be_v common_a to_o all_o solid_a body_n we_o may_v conclude_v that_o if_o no_o other_o circumstance_n concur_v the_o effect_n arise_v out_o of_o they_o will_v
