to_o act_v on_o 3._o that_o a_o alteration_n of_o the_o mechanical_a texture_n of_o the_o body_n be_v enough_o to_o dispose_v it_o or_o render_v it_o unapt_a to_o be_v work_v on_o by_o those_o unheeded_a agent_n and_o these_o three_o proposition_n i_o shall_v endeavour_v to_o make_v out_o by_o the_o follow_a phaenomena_n and_o experiment_n to_o begin_v then_o with_o the_o first_o proposition_n viz._n that_o some_o body_n be_v altogether_o inactive_a till_o they_o be_v act_v on_o and_o that_o other_o be_v put_v into_o action_n first_o proposition_n the_o first_o chief_o by_o

some_o of_o they_o be_v entangle_v together_o must_v needs_o be_v at_o rest_n and_o hence_o the_o primary_n affection_n of_o matter_n flow_v but_o there_o be_v yet_o other_o affection_n of_o matter_n

the_o volatile_a salt_n of_o hartshorn_n be_v very_o strong_a scent_v and_o of_o as_o strong_a a_o taste_n to_o which_o a_o great_a many_o more_o example_n may_v be_v add_v be_v it_o necessary_a difficulty_n consideration_n in_o order_n to_o remove_v the_o difficulty_n but_o i_o shall_v rather_o since_o it_o be_v not_o requisite_a offer_v the_o follow_a consideration_n to_o remove_v the_o difficulty_n first_o that_o several_a heterogeneous_a part_n may_v be_v lodge_v in_o the_o pore_n of_o a_o body_n which_o though_o of_o a_o different_a nature_n from_o the_o body_n itself_o yet_o they_o may_v produce_v some_o considerable_a effect_n as_o in_o perfume_a glove_n the_o odoriferous_a part_n be_v both_o different_a in_o substance_n and_o have_v different_a quality_n from_o the_o leather_n the_o glove_n be_v make_v of_o the_o second_o consideration_n be_v that_o part_n of_o very_o different_a nature_n may_v be_v link_v together_o not_o in_o a_o essential_a structure_n but_o a_o juxta-position_n or_o peculiar_a kind_n of_o composition_n and_o yet_o afford_v the_o same_o quality_n notwithstanding_o their_o essential_a difference_n for_o invisible_a change_n in_o some_o

denominate_v they_o of_o different_a species_n so_o a_o bar_n of_o iron_n by_o be_v hammer_v may_v feel_v hot_a though_o there_o be_v no_o visible_a alteration_n in_o the_o nature_n of_o the_o metal_n by_o a_o intense_a agitation_n of_o the_o insensible_a part_n of_o it_o but_o to_o illustrate_v this_o consideration_n a_o little_a further_o though_o a_o piece_n of_o iron_n wood_n or_o tin_n shall_v have_v sharp_a protuberant_a part_n yet_o be_v they_o distinct_a substance_n notwithstanding_o they_o all_o agree_v in_o that_o quality_n of_o roughness_n and_o if_o those_o rough_a part_n be_v wear_v off_o and_o the_o body_n endow_v with_o a_o smooth_a quality_n yet_o still_o will_v they_o in_o respect_n of_o their_o substance_n remain_v unaltered_a and_o though_o the_o superficies_n of_o steel_n brass_n flint_n or_o marble_n shall_v be_v polish_v as_o to_o become_v specular_a their_o essential_a difference_n will_v still_o be_v the_o same_o and_o as_o i_o take_v notice_n before_o though_o air_n be_v put_v into_o a_o undulate_a motion_n by_o different_a instrument_n yet_o if_o the_o motion_n be_v raise_v to_o the_o same_o degree_n it_o cause_v the_o same_o sound_n and_o produce_v the_o
