for_o the_o most_o part_n decline_v some_o way_n by_o reason_n of_o their_o weight_n angle_n now_o the_o particular_a law_n of_o reflection_n be_v that_o the_o line_n incident_a and_o the_o line_n

as_o will_v break_v clean_o by_o the_o force_n of_o the_o ball_n strike_v smart_o upon_o it_o and_o because_o that_o superficies_n resist_v only_o one_o way_n therefore_o he_o infer_v that_o the_o

of_o spirit_n yet_o in_o both_o kind_n they_o may_v have_v common_a difference_n for_o in_o abundance_n the_o pulse_n may_v be_v quick_a or_o slow_a regular_a or_o irregular_a equal_a or_o unequal_a and_o the_o like_a may_v happen_v in_o defect_n of_o spirit_n according_a to_o the_o motion_n of_o the_o hart_n which_o be_v their_o cause_n again_o the_o object_n by_o be_v present_a or_o absent_a near_a or_o further_o off_o make_v the_o stroke_n great_a or_o lesser_a and_o according_o vary_v the_o motion_n of_o the_o hart_n let_v we_o then_o call_v to_o mind_n how_o we_o have_v former_o

motion_n which_o be_v most_o lively_a must_v have_v a_o great_a full_a and_o large_a stroke_n like_o the_o even_o roll_a wave_n of_o a_o wide_a and_o smooth_a sea_n and_o not_o too_o quick_a or_o

that_o joy_n and_o grief_n follow_v the_o stroke_n of_o sense_n the_o one_o of_o they_o must_v consist_v in_o a_o oily_a dilatation_n that_o be_v the_o spirit_n about_o the_o hart_n must_v be_v

what_o withstand_v their_o motion_n go_v on_o with_o a_o great_a violence_n than_o they_o do_v and_o as_o it_o be_v precipitately_a so_o the_o hart_n have_v overcome_v the_o contraction_n which_o the_o sense_n make_v in_o it_o dilate_v itself_o with_o a_o fury_n and_o make_v its_o motion_n smart_n and_o vehement_a whence_o also_o it_o follow_v that_o the_o spirit_n grow_v hot_a than_o they_o

they_o before_o their_o spirit_n can_v relent_v their_o vehement_a motion_n and_o therefore_o must_v still_o increase_v it_o be_v anger_v into_o fever_n this_o passion_n of_o anger_n seem_v almost_o to_o be_v solitary_a on_o the_o side_n of_o excess_n beyond_o joy_n which_o be_v as_o it_o be_v the_o standard_n and_o perfection_n of_o all_o passion_n as_o light_n or_o whiteness_n be_v of_o all_o

which_o i_o conceive_v we_o may_v safe_o add_v that_o it_o must_v also_o be_v small_a and_o feeble_a the_o perfection_n of_o joy_n decrease_v in_o it_o on_o one_o side_n to_o wit_n from_o greatness_n

show_v we_o that_o the_o less_o the_o atom_n shall_v penetrate_v into_o a_o move_a body_n by_o reason_n of_o the_o extreme_a density_n of_o it_o the_o more_o efficacious_o they_o will_v work_v and_o

peradventure_o say_v that_o if_o these_o stroke_n of_o the_o descend_a atom_n upon_o a_o dense_a body_n be_v the_o cause_n of_o its_o motion_n downwards_o we_o must_v allow_v the_o atom_n to_o move_v fast_o than_o the_o dense_a body_n that_o so_o they_o may_v still_o overtake_v it_o and_o drive_v it_o along_o and_o enter_v into_o it_o whereas_o if_o they_o shall_v move_v slow_a than_o it_o none_o of_o they_o can_v come_v in_o their_o turn_n to_o give_v it_o a_o stroke_n but_o it_o will_v be_v pass_v they_o and_o out_o of_o their_o reach_n before_o they_o can_v strike_v it_o but_o it_o be_v

to_o this_o i_o reply_v that_o to_o have_v the_o atom_n give_v these_o blow_n to_o a_o descend_v dense_a body_n do_v not_o require_v that_o their_o natural_a and_o ordinary_a motion_n shall_v be_v
