from_o the_o orifice_n you_o may_v observe_v continual_a bubble_n of_o air_n to_o pass_v through_o the_o water_n by_o a_o ebullition_n and_o so_o present_o to_o create_v the_o little_a cap_n of_o

the_o quicksilver_n in_o the_o tube_n be_v depress_v by_o the_o superincumbent_n cylinder_n of_o water_n of_o 14._o inch_n it_o follow_v that_o it_o will_v necessary_o depress_v it_o one_o inch_n low_o than_o the_o ordinary_a stint_n but_o unless_o the_o cylinder_n of_o quicksilver_n be_v so_o great_a or_o at_o least_o that_o of_o quicksilver_n and_o water_n to_o be_v so_o powerful_a as_o that_o it_o be_v able_a to_o overcome_v the_o elastic_a pressure_n of_o the_o atmosphaere_n no_o effect_n at_o all_o will_v follow_v because_o there_o can_v be_v no_o descent_n of_o either_o and_o as_o for_o those_o aerial_a atom_n which_o pass_v by_o bubble_n through_o the_o body_n of_o the_o water_n they_o be_v those_o former_o observe_v for_o to_o lurk_v betwixt_o the_o contiguity_n of_o the_o quicksilver_n and_o tube_n nay_o and_o perchance_o and_o in_o the_o body_n of_o the_o quicksilver_n and_o water_n too_o because_o they_o cease_v not_o after_o the_o collapsion_n and_o descent_n of_o the_o mercury_n thus_o have_v mechanical_o evince_v the_o gravitation_n of_o those_o two_o fluid_a element_n both_o water_n and_o air_n in_o their_o proper_a place_n and_o region_n we_o may_v

so_o to_o fall_v that_o it_o come_v down_o 16._o inch_n low_a than_o its_o wont_a and_o determinate_a altitude_n we_o fill_v the_o same_o tube_n of_o 45._o inch_n long_o within_o two_o inch_n of_o
