no_o the_o artery_n and_o vein_n be_v quite_o full_a of_o blood_n since_o that_o as_o the_o blood_n decrease_v in_o they_o the_o muscle_n of_o the_o limb_n and_o other_o adjacent_a part_n do_v proportionable_o compress_v they_o round_o about_o so_o that_o their_o internal_a superficies_n touch_v the_o blood_n continual_o every_o way_n which_o have_v the_o same_o effect_n as_o if_o the_o artery_n and_o vein_n be_v exact_o full_a of_o blood_n for_o the_o blood_n come_v out_o of_o the_o heart_n and_o find_v as_o much_o difficulty_n in_o lift_v up_o the_o adjacent_a part_n as_o to_o drive_v on_o the_o blood_n of_o the_o artery_n and_o vein_n when_o they_o be_v full_a on_o it_o it_o be_v force_v to_o keep_v the_o same_o order_n and_o method_n in_o that_o case_n as_o it_o do_v in_o this_o concern_v its_o dilatation_n and_o place_n in_o the_o artery_n now_o these_o be_v the_o true_a and_o genuine_a reason_n of_o the_o diastole_n and_o systole_n of_o the_o artery_n it_o be_v very_o easy_a thereby_o to_o explain_v all_o the_o phenomena_n relate_v to_o galen_n experiment_n for_o the_o quill_n be_v put_v into_o the_o artery_n and_o leave_v there_o without_o be_v tie_v the_o artery_n will_v nevertheless_o beat_v still_o above_o and_o below_o the_o quill_n as_o it_o do_v before_o because_o that_o the_o spiral_n fibres_fw-fr can_v still_o play_v to_o and_o fro_o from_o one_o end_n of_o the_o artery_n to_o the_o other_o without_o impediment_n but_o if_o you_o bind_v the_o side_n of_o the_o artery_n upon_o the_o quill_n the_o motion_n of_o the_o same_o spiral_n

which_o be_v between_o the_o arterial_a and_o venal_a blood_n for_o have_v demonstrate_v above_o that_o when_o the_o blood_n advance_v in_o the_o great_a artery_n from_o the_o heart_n towards_o the_o
