red_a wine_n be_v red_a of_o its_o self_n but_o rather_o as_o the_o glass_n appear_v red_a because_o the_o liquor_n that_o be_v within_o it_o be_v of_o that_o colour_n even_o so_o flesh_n and_o all_o the_o other_o part_n of_o the_o body_n of_o a_o animal_n appear_v red_a only_o because_o of_o the_o redness_n of_o the_o blood_n which_o be_v contain_v in_o the_o vein_n and_o artery_n of_o these_o

which_o spread_v their_o banche_n through_o the_o flesh_n after_o you_o have_v repeat_v frequent_o the_o injection_n the_o flesh_n become_v of_o the_o colour_n of_o the_o tendon_n the_o muscle_n be_v not_o only_o compose_v of_o artery_n vein_n and_o tendinous_a fibres_n but_o the_o nerve_n also_o make_v one_o of_o their_o part_n they_o march_v first_o upon_o their_o coat_n and_o pierce_v it_o when_o they_o have_v pierce_v it_o they_o divide_v themselves_o in_o most_o delicate_a branch_n which_o be_v mosculate_v with_o the_o tendinous_a fibres_fw-fr sometime_o the_o nerve_n enter_v into_o the_o tendon_n and_o sometime_o into_o the_o belly_n of_o the_o muscle_n but_o in_o what_o part_n soever_o they_o enter_v we_o find_v always_o the_o extremite_n of_o their_o branch_n to_o end_v at_o the_o tendinous_a fibres_fw-fr all_o these_o tendinons_n fibre_n have_v a_o cavity_n that_o go_v through_o they_o like_v unto_o a_o tube_n or_o pipe_n indeed_o this_o cavity_n can_v be_v see_v by_o the_o eye_n but_o there_o be_v a_o experiment_n which_o abundant_o show_v the_o necessity_n of_o it_o that_o it_o can_v be_v contradict_v by_o those_o who_o will_v hearken_v to_o reason_n the_o experiment_n be_v that_o always_o when_o a_o muscle_n act_n its_o fibre_n be_v considerable_o shorten_v and_o in_o the_o mean_a time_n they_o swell_v big_a nevertheless_o we_o can_v conceive_v how_o flexible_a fibres_n can_v swell_v big_a and_o be_v shorten_v at_o the_o same_o time_n but_o by_o the_o mean_n of_o some_o liquor_n which_o fill_v a_o cavity_n that_o pierce_v they_o from_o one_o end_n to_o the_o other_o after_o this_o it_o will_v not_o be_v very_o hard_a to_o discover_v how_o all_o these_o thing_n must_v act_v each_o tendinous_a fiber_n receive_v a_o branch_n of_o a_o nerve_n and_o each_o branch_n of_o the_o nerve_n shed_v animal_n spirit_n into_o the_o cavity_n of_o the_o tendinous_a fiber_n the_o animal_n spirit_n be_v the_o most_o subtle_a and_o the_o most_o agitate_a part_n of_o the_o blood_n when_o they_o enter_v into_o the_o cavity_n of_o the_o tendinous_a fibres_fw-fr they_o blow_v they_o up_o and_o shorten_v they_o even_o as_o the_o air_n which_o be_v blow_v into_o a_o bladder_n swell_v it_o and_o shorten_v it_o at_o the_o same_o time_n if_o we_o consider_v after_o this_o that_o the_o belly_n of_o the_o muscle_n be_v stuff_v throughout_o with_o artery_n and_o vein_n we_o will_v grant_v that_o the_o tendinous_a fibre_n can_v be_v blow_v up_o without_o diminish_v the_o cavity_n of_o the_o artery_n and_o vein_n from_o whence_o if_o follow_v that_o the_o blood_n be_v drive_v out_o of_o they_o it_o be_v for_o this_o that_o in_o some_o animal_n the_o muscle_n become_v white_a always_o when_o the_o animal_n spirit_n do_v dilate_v the_o tendinous_a fibres_fw-fr if_o in_o fine_a we_o take_v notice_n that_o when_o the_o blood_n stop_v in_o the_o artery_n and_o vein_n the_o tendinous_a fibre_n do_v not_o receive_v enough_o or_o motion_n from_o the_o animal_n spirit_n to_o thrust_v forward_o that_o blood_n which_o stay_v among_o they_o from_o hence_o it_o follow_v that_o in_o such_o rencounter_v they_o can_v dilate_v nor_o become_v short_a from_o hence_o we_o may_v conclude_v that_o there_o be_v two_o thing_n absolute_o necessary_a for_o the_o blow_v up_o of_o the_o tendinous_a fibres_fw-fr of_o the_o muscle_n the_o first_o be_v that_o
