i_o shall_v before_o i_o proceed_v to_o show_v how_o the_o heat_n of_o the_o blood_n be_v cause_v endeavour_v to_o demonstrate_v those_o spirit_n and_o prove_v that_o they_o circulate_v through_o

their_o nature_n which_o appear_v as_o manifest_o as_o the_o humour_n of_o a_o man_n body_n but_o perhaps_o it_o will_v be_v a_o hard_a task_n to_o brain_n persuade_v some_o that_o that_o oily_a and_o clammy_a moisture_n in_o the_o brain_n be_v animal_n spirit_n since_o it_o seem_v as_o some_o say_v to_o be_v as_o gross_a a_o substance_n as_o any_o liquid_a in_o the_o body_n to_o this_o i_o answer_v that_o if_o we_o take_v animal_n spirit_n answer_v or_o that_o moisture_n in_o the_o brain_n and_o compare_v it_o with_o coagulate_v blood_n it_o be_v much_o more_o fine_a and_o pure_a and_o not_o half_a so_o tough_a and_o clammy_a whereas_o if_o it_o be_v a_o more_o gross_a and_o sluggish_a body_n it_o will_v be_v a_o great_a deal_n more_o viscid_a and_o phlegmatic_a but_o if_o we_o further_o compare_v the_o taste_n of_o the_o prove_v brain_n with_o the_o taste_n of_o the_o blood_n it_o will_v be_v evident_a that_o that_o sweet_a substance_n be_v the_o spirit_n of_o the_o blood_n and_o consequent_o that_o it_o be_v animal_n spirit_n for_o as_o the_o blood_n be_v a_o sweet_a mass_n inpregnate_v with_o diverse_a sort_n of_o salt_n and_o phlegmatic_a crude_a serum_n so_o the_o substance_n of_o the_o brain_n be_v moisten_v with_o a_o oily_a sweet_a salino-sulphureous_a mass_n free_a from_o those_o indigested_a dregs_o that_o swim_v along_o with_o the_o blood_n be_v separate_v from_o those_o impurities_n in_o the_o cortical_a part_n of_o the_o brain_n now_o if_o a_o spirit_n partake_v of_o the_o nature_n of_o that_o body_n it_o be_v separate_v or_o draw_v from_o this_o be_v a_o argument_n strong_a enough_o to_o convince_v any_o rational_a man_n that_o that_o moisture_n be_v the_o spirit_n of_o the_o body_n since_o we_o learn_v by_o our_o taste_n that_o it_o be_v the_o pure_a and_o most_o refine_a part_n of_o the_o blood_n as_o a_o spirit_n ought_v to_o be_v but_o some_o think_v it_o too_o gross_a a_o humour_n to_o do_v perform_v all_o those_o action_n which_o they_o think_v the_o animal_n spirit_n do_v yet_o if_o they_o grant_v that_o the_o mass_n of_o blood_n be_v the_o pabulum_fw-la of_o the_o animal_n spirit_n as_o i_o think_v none_o can_v deny_v since_o any_o considerable_a evacuation_n of_o it_o present_o sink_v and_o diminish_v they_o than_o it_o will_v be_v very_o manifest_a that_o those_o spirit_n be_v able_a to_o perform_v all_o those_o action_n that_o we_o can_v true_o suppose_v animal_n spirit_n to_o do_v for_o if_o by_o withdraw_v that_o sweet_a viscid_n pabulum_fw-la that_o sweet_a oily_a mucilaginous_a moisture_n in_o the_o brain_n be_v diminish_v and_o upon_o that_o diminution_n the_o animal_n spirit_n be_v present_o less_o vigorous_a and_o on_o the_o contrary_a if_o by_o enrich_v the_o blood_n and_o consequent_o increase_a the_o stock_n of_o animal_n spirit_n the_o action_n of_o the_o body_n as_o well_o as_o of_o the_o mind_n be_v strong_a we_o must_v consequent_o believe_v that_o they_o be_v moderate_o perform_v by_o they_o when_o that_o oily_a substance_n neither_o too_o plentiful_o abound_v nor_o be_v too_o much_o spend_v and_o consume_v but_o some_o people_n will_v not_o believe_v that_o to_o
