the_o meaning_n be_v that_o more_o quantity_n be_v contract_v to_o less_o whereby_o the_o bensil_n of_o it_o be_v more_o intend_a or_o that_o the_o air_n be_v more_o bend_a as_o for_o the_o second_o we_o must_v remember_v from_o the_o last_o experiment_n that_o the_o cause_n of_o this_o be_v not_o from_o the_o water_n as_o if_o forsooth_o the_o pressure_n of_o it_o be_v according_a to_o unequal_a

during_o the_o down_o go_v of_o the_o ark_n there_o be_v still_o equality_n of_o weight_n between_o the_o pondus_fw-la of_o the_o water_n and_o the_o potentia_fw-la of_o the_o air_n for_o with_o
