the_o art_n to_o scour_v and_o wash_v away_o and_o therefore_o i_o think_v it_o no_o great_a wonder_n to_o bring_v those_o sand_n into_o one_o lump_n though_o i_o know_v not_o how_o they_o do_v it_o a._n i_o know_v they_o do_v it_o with_o lie_v make_v with_o a_o salt_n extract_v from_o the_o ash_n of_o a_o herb_n of_o which_o salt_n they_o make_v a_o strong_a lie_n and_o mingle_v it_o with_o the_o sand_n and_o then_o bake_v it_o b._n like_a enough_o but_o still_o it_o be_v a_o compound_v of_o two_o transparent_a body_n whereof_o one_o be_v the_o natural_a stone_n the_o other_o be_v the_o

body_n of_o many_o why_o do_v they_o not_o of_o a_o great_a many_o small_a spark_n of_o natural_a diamant_n compound_v one_o great_a one_o it_o will_v bear_v the_o charge_n of_o all_o the_o material_n

and_o make_v by_o the_o earth_n annual_a motion_n for_o it_o be_v a_o very_a swift_a motion_n suppose_v now_o that_o within_o a_o very_a small_a cavern_n of_o those_o rock_n who_o small_a atom_n be_v

the_o force_n of_o the_o air_n that_o can_v break_v off_o those_o diaphanous_a atom_n in_o a_o cavern_n can_v do_v the_o same_o in_o the_o open_a air._n and_o i_o know_v that_o a_o less_o force_n of_o
