but_o as_o far_o as_o we_o can_v discern_v there_o happen_v no_o great_a alteration_n to_o the_o liquor_n which_o seem_v the_o less_o strange_a because_o the_o spring_n of_o that_o air_n that_o may_v

it_o as_o may_v happen_v in_o some_o mercurial_a experiment_n it_o be_v to_o be_v consider_v that_o the_o air_n be_v a_o fluid_a as_o well_o as_o a_o heavy_a body_n it_o do_v not_o as_o grosser_n

that_o though_o by_o the_o help_n of_o the_o handle_n the_o sucker_n be_v easy_o draw_v down_o to_o the_o bottom_n of_o the_o cylinder_n yet_o without_o the_o help_n of_o that_o leaver_n there_o will_v be_v require_v to_o the_o same_o effect_n a_o force_n or_o weight_n great_a enough_o to_o surmount_v the_o pressure_n of_o the_o whole_a atmosphere_n since_o otherwise_o the_o air_n will_v not_o be_v drive_v out_o of_o its_o place_n when_o none_o be_v permit_v to_o succeed_v into_o the_o place_n desert_v by_o the_o sucker_n this_o seem_v evident_a from_o the_o know_a torricellian_a experiment_n in_o which_o if_o the_o invert_v tube_n of_o mercury_n be_v but_o 25_o digit_n high_a or_o somewhat_o more_o the_o quicksilver_n will_v not_o fall_v but_o remain_v suspend_v in_o the_o tube_n because_o it_o can_v press_v the_o subjacent_a mercury_n with_o so_o great_a a_o force_n as_o do_v the_o incumbent_n cylinder_n of_o the_o air_n reach_v thence_o to_o the_o top_n of_o the_o atmosphere_n whereas_o if_o the_o cylinder_n of_o mercury_n be_v three_o or_o four_o digit_n long_o it_o will_v overpower_v that_o of_o the_o external_a air_n and_o run_v out_o into_o the_o vesseled_a mercury_n till_o the_o two_o cylinder_n come_v to_o a_o aequilibrium_fw-la and_o no_o further_o hence_o we_o need_v not_o wonder_n that_o though_o the_o sucker_n move_v easy_o enough_o up_o and_o down_o in_o the_o cylinder_n by_o the_o help_n of_o the_o manubrium_fw-la yet_o if_o the_o manubrium_fw-la be_v take_v off_o it_o will_v require_v a_o considerable_a strength_n to_o move_v it_o either_o way_n nor_o will_v it_o seem_v strange_a that_o if_o when_o the_o valve_n and_o stop-cock_n be_v well_o shut_v you_o draw_v down_o the_o sucker_n and_o then_o let_v go_v the_o manubrium_fw-la the_o sucker_n will_v as_o it_o be_v of_o itself_o re-ascend_a to_o the_o top_n of_o the_o cylinder_n since_o the_o spring_n of_o the_o external_a air_n find_v nothing_o to_o resist_v its_o press_v up_o the_o sucker_n and_o for_o the_o same_o reason_n when_o the_o receiver_n be_v almost_o evacuate_v though_o have_v draw_v down_o the_o sucker_n you_o open_v the_o way_n from_o the_o receiver_n to_o the_o cylinder_n and_o then_o intercept_v that_o way_n again_o by_o return_v the_o key_n the_o sucker_n will_v upon_o the_o let_a go_v the_o manubrium_fw-la be_v forcible_o carry_v up_o almost_o to_o the_o top_n of_o the_o cylinder_n because_o the_o air_n within_o the_o cylinder_n be_v equal_o dilate_v and_o weaken_v with_o that_o of_o the_o glass_n be_v unable_a to_o withstand_v the_o pressure_n of_o the_o external_a air_n till_o it_o be_v drive_v into_o so_o little_a space_n that_o there_o be_v a_o aequilibrium_fw-la betwixt_o its_o force_n and_o that_o of_o the_o air_n without_o and_o congruous_o hereunto_o we_o find_v that_o in_o this_o case_n the_o sucker_n be_v draw_v down_o with_o little_o less_o difficulty_n than_o if_o the_o cylinder_n be_v devoid_a of_o air_n the_o stop-cock_n be_v exact_o shut_v we_o may_v take_v notice_n of_o some_o other_o thing_n that_o depend_v upon_o the_o fabric_n of_o our_o engine_n itself_o but_o to_o shun_v prolixity_n we_o will_v in_o this_o place_n content_v ourselves_o to_o mention_v one_o of_o they_o which_o seem_v to_o be_v of_o great_a moment_n than_o the_o rest_n and_o it_o be_v this_o that_o when_o the_o sucker_n have_v be_v impel_v to_o the_o top_n of_o the_o cylinder_n and_o the_o valve_n be_v so_o careful_o stop_v that_o there_o be_v no_o air_n leave_v in_o the_o cylinder_n above_o the_o sucker_n if_o then_o the_o sucker_n be_v draw_v to_o the_o low_a part_n of_o the_o cylinder_n he_o that_o manage_v the_o pump_n find_v not_o any_o sensible_o great_a difficulty_n to_o depress_v the_o sucker_n when_o it_o be_v near_o the_o bottom_n of_o the_o cylinder_n than_o when_o it_o be_v much_o far_o off_o which_o circumstance_n we_o therefore_o think_v fit_a to_o take_v notice_n of_o because_o a_o eminent_a modern_a naturalist_n have_v teach_v that_o when_o the_o air_n be_v suck_v out_o of_o a_o body_n the_o violence_n wherewith_o it_o be_v wont_a to_o rush_v into_o it_o again_o as_o soon_o as_o it_o be_v allow_v to_o re-enter_v proceed_v main_o from_o this_o that_o the_o pressure_n of_o the_o ambient_fw-la air_n be_v strengthen_v upon_o the_o accession_n of_o the_o air_n suck_v out_o which_o to_o make_v itself_o room_n force_v the_o neighbour_a air_n to_o a_o violent-subingression_a of_o its_o part_n which_o if_o it_o be_v true_a he_o that_o draw_v down_o the_o sucker_n will_v find_v the_o resistance_n of_o the_o external_a air_n increase_v as_o he_o draw_v it_o low_o more_o of_o the_o displace_v air_n be_v thrust_v into_o it_o to_o compress_v it_o but_o by_o what_o have_v be_v discourse_v upon_o the_o first_o experiment_n it_o seem_v more_o probable_a that_o without_o any_o such_o strengthen_n of_o the_o pressure_n of_o the_o outward_a air_n the_o take_v quite_o away_o or_o the_o debilitate_v of_o the_o resistance_n from_o within_o may_v suffice_v to_o produce_v the_o effect_n under_o consideration_n but_o this_o will_v perhaps_o be_v illustrate_v by_o some_o or_o
