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

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

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

the_o more_o their_o fluidity_n be_v increase_v body_n a_o fluid_n may_v be_v obtain_v from_o a_o consistent_a body_n and_o here_o it_o may_v not_o be_v unseasonable_a to_o inquire_v how_o it_o come_v to_o pass_v that_o a_o transparent_a liquor_n shall_v be_v draw_v from_o such_o brittle_a body_n as_o common_a salt_n i_o know_v it_o be_v usual_o allege_v that_o the_o fire_n only_o separate_v the_o

it_o be_v rather_o probable_a that_o the_o fire_n only_o divide_v their_o part_n and_o put_v they_o into_o a_o violent_a agitation_n by_o which_o they_o be_v raise_v in_o the_o form_n of_o vapour_n
