as_o our_o receiver_n be_v that_o the_o quicksilver_n by_o its_o sudden_a descent_n acquire_v a_o impetus_fw-la superad_v to_o the_o pressure_n it_o have_v upon_o the_o score_n of_o its_o wont_a

nor_o will_v it_o necessary_o follow_v that_o the_o space_n which_o the_o flame_n seem_v to_o take_v up_o shall_v contain_v neither_o air_n nor_o aether_n nor_o any_o thing_n else_o save_o the_o part_n of_o that_o flame_n because_o the_o eye_n can_v discern_v any_o other_o body_n there_o for_o even_o the_o smoke_n ascend_v from_o the_o snuff_n of_o a_o newly-extinguished_a candle_n appear_v a_o dark_a pillar_n which_o to_o the_o eye_n at_o some_o distance_n seem_v to_o consist_v of_o smoke_n whenas_o yet_o there_o be_v so_o many_o aerial_a and_o other_o invisible_a corpuscle_n mingle_v with_o it_o as_o if_o all_o those_o part_n of_o smoke_n that_o make_v a_o great_a show_n in_o the_o air_n be_v collect_v and_o contiguous_a they_o will_v not_o perhaps_o amount_v to_o the_o bigness_n

therefore_o it_o do_v not_o ill_o fall_v out_o for_o our_o turn_n that_o the_o examiner_n to_o enforce_v his_o former_a example_n allege_v the_o turn_n of_o a_o particle_n of_o quicksilver_n into_o vapour_n by_o put_v fire_n under_o it_o for_o if_o such_o be_v the_o rarefaction_n of_o mercury_n it_o be_v not_o at_o all_o like_a to_o make_v such_o a_o funiculus_fw-la as_o he_o talk_v of_o since_o those_o mercurial_a fume_n appear_v by_o divers_a experiment_n to_o be_v mercury_n divide_v and_o throw_v abroad_o into_o minute_n part_n whereby_o though_o the_o body_n obtain_v more_o of_o surface_n than_o it_o have_v before_o yet_o it_o real_o fill_v no_o more_o of_o true_a and_o genuine_a space_n since_o if_o all_o the_o particular_a little_a space_n fill_v by_o these_o scatter_a corpuscle_n be_v reduce_v into_o one_o as_o the_o corpuscle_n themselves_o often_o be_v in_o chemical_a operation_n they_o will_v amount_v but_o to_o one_o total_a space_n equal_a to_o that_o of_o the_o whole_a

it_o be_v also_o somewhat_o strange_a that_o water_n and_o other_o fluid_a body_n who_o part_n be_v wont_a to_o be_v so_o easy_o separable_a shall_v when_o the_o funiculus_fw-la once_o lay_n hold_v
