show_v that_o the_o pore_n of_o the_o part_n of_o animal_n whether_o fluid_a or_o consistent_a be_v plentiful_o stock_v with_o numerous_a aerial_a bubble_n which_o cause_n those_o body_n to_o swell_v

yet_o those_o that_o have_v be_v upon_o those_o mountain_n tell_v we_o that_o they_o perceive_v no_o considerable_a difference_n in_o the_o pressure_n of_o the_o atmosphere_n above_o and_o below_o
