the_o generation_n of_o vital_a spirit_n seem_v to_o be_v the_o chief_a use_n of_o the_o air_n in_o breathe_v in_o regard_n it_o be_v not_o easy_a to_o conceive_v any_o such_o contrivance_n in_o the_o

of_o the_o blood_n life_n chief_o consist_v and_o if_o the_o same_o by_o any_o chance_n shall_v cease_v or_o intermit_v though_o but_o for_o a_o very_a small_a time_n less_o than_o a_o minute_n death_n will_v unavoidable_o follow_v in_o this_o motion_n of_o the_o blood_n it_o be_v observable_a first_o that_o as_o the_o pulsation_n of_o the_o heart_n send_v it_o through_o the_o artery_n into_o the_o whole_a habit_n of_o the_o body_n so_o the_o return_n of_o it_o by_o the_o vein_n seem_v to_o depend_v chief_o upon_o the_o tonical_a motion_n of_o the_o body_n for_o the_o part_n be_v extend_v by_o the_o flow_a in_o of_o the_o blood_n somewhat_o beyond_o their_o tone_n do_v again_o gentle_o subside_o and_o thereby_o continue_v the_o intend_a course_n of_o the_o blood_n towards_o the_o heart_n again_o a_o argument_n hereof_o be_v that_o all_o paralytic_a part_n grow_v immediate_o cold_a and_o that_o for_o no_o other_o reason_n than_o that_o the_o tonical_a motion_n together_o with_o the_o power_n locomotive_a cease_v the_o circulation_n be_v either_o very_o weak_o or_o not_o at_o all_o perform_v through_o that_o part_n which_o then_o grow_v cold_a for_o want_v of_o that_o constant_a fresh_a supply_n of_o blood_n which_o former_o keep_v it_o warm_a but_o herein_o the_o tonical_a motion_n be_v not_o a_o little_a help_v by_o exercise_n and_o labour_n which_o we_o find_v by_o experience_n to_o cause_v the_o heart_n to_o beat_v quick_a and_o often_o as_o also_o to_o induce_v a_o necessity_n of_o breathe_v more_o frequent_o and_o this_o it_o do_v no_o otherwise_o than_o by_o accelerate_v this_o circular_a motion_n of_o the_o blood_n which_o then_o enforce_v the_o heart_n and_o lung_n to_o double_a duty_n our_o second_o observable_a in_o this_o circular_a motion_n of_o the_o blood_n be_v that_o there_o pass_v as_o much_o blood_n from_o the_o right_a ventricle_n of_o the_o heart_n into_o the_o â—uâ—gs_n at_o every_o pulse_n take_v one_o time_n with_o another_o

only_o and_o the_o lung_n receive_v it_o not_o elsewhere_o than_o from_o the_o right_a ventricle_n of_o the_o heart_n so_o that_o to_o continue_v this_o circular_a motion_n of_o the_o blood_n it_o be_v necessary_a the_o supply_n neither_o exceed_v nor_o come_v short_a of_o that_o quantity_n dispense_v from_o the_o left_a ventricle_n of_o the_o heart_n into_o the_o whole_a body_n the_o lung_n except_v from_o hence_o it_o follow_v that_o there_o flow_v a_o great_a quantity_n of_o blood_n by_o many_o degree_n into_o the_o lung_n than_o what_o be_v sufficient_a for_o its_o own_o private_a use_n as_o also_o that_o the_o blood_n in_o the_o lung_n must_v of_o necessity_n move_v very_o much_o fast_o than_o it_o do_v in_o any_o part_n of_o the_o body_n though_o we_o take_v for_o example_n the_o great_a vein_n or_o artery_n themselves_o and_o that_o in_o the_o same_o proportion_n as_o the_o vena_fw-la arteriosa_fw-la and_o arteria_fw-la venosa_fw-la be_v small_a than_o the_o trunk_n

the_o parenchyma_n of_o the_o lung_n and_o that_o at_o a_o much_o swift_a rate_n than_o it_o do_v through_o any_o part_n of_o the_o whole_a body_n beside_o 3._o far_o before_o we_o proceed_v to_o

or_o artery_n of_o the_o neck_n flow_v thither_o very_o crude_a and_o accompany_v with_o all_o its_o excrement_n it_o have_v not_o yet_o receive_v or_o suffer_v any_o depuration_n or_o alteration_n from_o the_o reins_o or_o spleen_n like_o that_o which_o pass_v into_o almost_o all_o other_o especial_o the_o low_a part_n of_o the_o body_n though_o indeed_o it_o seem_v not_o to_o be_v cleanse_v of_o the_o gall_n till_o it_o return_v home_o again_o through_o the_o liver_n now_o though_o nature_n purpose_n herein_o be_v very_o obscure_a that_o the_o blood_n thus_o impure_a shall_v be_v

part_n of_o the_o blood_n send_v to_o the_o head_n which_o the_o reins_o do_v execute_v to_o the_o remain_a mass_n hence_o no_o wonder_n it_o be_v if_o excessive_a drink_n do_v so_o much_o weaken_v
