of_o the_o part_n of_o matter_n three_o that_o they_o be_v attribute_v to_o body_n upon_o the_o account_n of_o some_o particular_a quality_n as_o unctuousness_n in_o oil_n etc._n etc._n or_o some_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

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

before_o deliver_v i_o shall_v conclude_v with_o this_o reflection_n viz._n that_o in_o all_o the_o change_n and_o alteration_n that_o have_v be_v effect_v by_o art_n it_o appear_v that_o they_o be_v

and_o
not_o pretend_v to_o decide_v the_o controversy_n whether_o body_n may_v be_v indefinite_o divide_v into_o small_a part_n but_o i_o will_v only_o intimate_v that_o though_o mental_o all_o body_n may_v

sufficient_a without_o the_o addition_n of_o a_o cement_n be_v evident_a since_o several_a piece_n of_o glass_n if_o exact_o fit_v and_o polish_a will_v adhere_v so_o firm_o together_o that_o by_o

of_o cohesion_n a_o example_n of_o which_o we_o have_v have_v in_o a_o glass_n stopple_n due_o adapt_v to_o the_o neck_n of_o a_o bottle_n by_o which_o the_o bottle_n contain_v a_o pound_n weight_n of_o liquor_n may_v several_a time_n be_v lift_v up_o from_o the_o table_n which_o can_v proceed_v from_o nothing_o but_o the_o close_a contact_n of_o those_o two_o body_n unless_o it_o be_v urge_v

influence_n of_o these_o catholic_n and_o unheeded_a agent_n the_o first_o part_n of_o this_o proposition_n i_o presume_v undeniable_a if_o we_o consider_v that_o till_o a_o hammer_n or_o some_o
