upward_o as_o any_o other_o way_n next_o we_o may_v consider_v that_o when_o the_o surface_v of_o two_o flat_a body_n of_o any_o notable_a and_o for_o example_n of_o equal_a breadth_n do_v immediate_o touch_v each_o other_o and_o lie_n both_o of_o they_o level_v with_o the_o horizon_n and_o one_o of_o they_o direct_o over_o the_o other_o in_o this_o case_n i_o say_v since_o the_o air_n can_v move_v

the_o abovemention_v cylinder_n of_o the_o atmosphere_n and_o this_o as_o i_o say_v because_o that_o by_o reason_n of_o the_o sudden_a separation_n the_o upper_a surface_n of_o the_o glass_n have_v not_o any_o air_n contiguous_a to_o it_o which_o be_v it_o there_o will_v according_a to_o the_o nature_n of_o fluid_n and_o springy_a body_n press_v as_o much_o against_o the_o upper_a surface_n of_o
