beside_o i_o will_v have_v they_o consider_v that_o the_o great_a artery_n and_o the_o arterious_a vein_n be_v of_o a_o composition_n much_o strong_a than_o the_o veinous_a artery_n or_o the_o

very_a hot_a vessel_n for_o after_o this_o i_o need_v say_v no_o more_o for_o to_o unfold_v the_o motion_n of_o the_o heart_n but_o that_o when_o these_o concavity_n be_v not_o full_a of_o blood_n necessary_o there_o run_v some_o from_o the_o vena_fw-la cava_fw-la into_o the_o right_a and_o from_o the_o veinous_a artery_n into_o the_o left_a for_o that_o these_o two_o vessel_n be_v always_o

through_o those_o two_o purse_n which_o be_v call_v the_o ear_n thence_o it_o come_v that_o their_o motion_n be_v contrary_a to_o the_o heart_n and_o that_o they_o fall_v when_o that_o swell_v last_o
