much_o more_o easy_a to_o be_v make_v than_o the_o experiment_n requisite_a to_o examine_v it_o for_o we_o find_v it_o no_o easy_a matter_n to_o suspend_v a_o electric_n great_a and_o vigorous_a

be_v that_o the_o body_n to_o be_v corrode_v be_v furnish_v with_o pore_n of_o such_o a_o bigness_n and_o figure_n that_o the_o corpuscle_n of_o the_o solvent_a may_v enter_v they_o and_o yet_o not_o

be_v for_o want_v of_o this_o condition_n that_o glass_n be_v penetrate_v in_o a_o multitude_n of_o place_n but_o not_o dissipate_v or_o dissolve_v by_o the_o incident_a beam_n of_o light_n which_o permeate_n its_o pore_n without_o any_o considerable_a resistance_n and_o though_o the_o pore_n and_o commissure_v of_o a_o body_n be_v less_o minute_n and_o capable_a of_o let_v in_o some_o grosser_n corpuscle_n yet_o if_o these_o be_v for_o want_v of_o solidity_n or_o rigidness_n too_o flexible_a or_o be_v of_o a_o figure_n incongruous_a to_o that_o of_o the_o pore_n they_o shall_v enter_v the_o dissolution_n will_v not_o ensue_v as_o it_o happen_v when_o pure_a spirit_n of_o wine_n be_v in_o the_o cold_a put_v upon_o salt_n of_o tartar_n or_o when_o aqua_n fortis_fw-la be_v put_v upon_o powder_n of_o sulphur_n the_o second_o qualification_n of_o a_o corrodible_a body_n be_v that_o its_o consistent_a corpuscle_n be_v of_o such_o a_o bulk_n and_o solidity_n as_o do_v not_o render_v they_o uncapable_a of_o be_v disjoin_v by_o the_o action_n of_o the_o insinuate_a corpuscle_n of_o the_o menstruum_fw-la agreeable_a to_o this_o and_o the_o former_a observation_n be_v the_o practice_n of_o chemist_n who_o oftentimes_o when_o they_o will_v have_v a_o body_n to_o be_v wrought_v on_o by_o a_o menstruum_fw-la otherwise_o too_o weak_a for_o it_o in_o its_o crude_a estate_n dispose_v it_o to_o receive_v the_o action_n of_o the_o menstruum_fw-la by_o previous_o open_v it_o as_o they_o speak_v that_o be_v by_o enlarge_a the_o pore_n make_v a_o comminution_n of_o the_o corpuscle_n or_o weaken_v their_o cohesion_n and_o we_o see_v that_o divers_a body_n be_v bring_v by_o fit_a preparation_n to_o be_v resoluble_a in_o liquor_n that_o will_v not_o work_v on_o they_o before_o thus_o as_o be_v late_o note_v limestone_n by_o calcination_n become_v in_o part_n dissoluble_a in_o water_n and_o some_o metalline_a calces_fw-la will_n be_v so_o wrought_v on_o by_o solvent_n as_o they_o will_v not_o be_v by_o the_o same_o agent_n if_o the_o preparation_n of_o the_o metalline_a or_o other_o body_n have_v not_o give_v they_o a_o new_a disposition_n thus_o though_o crude_a tartar_n especial_o in_o lump_n be_v very_o slow_o and_o difficult_o dissoluble_a in_o cold_a water_n yet_o when_o it_o be_v burn_v it_o may_v be_v present_o dissolve_v in_o that_o liquor_n and_o thus_o though_o the_o file_n and_o the_o calx_fw-la of_o silver_n will_v not_o be_v at_o all_o dissolve_v by_o common_a water_n or_o spirit_n of_o wine_n yet_o if_o by_o the_o interposition_n of_o the_o saline_n particle_n of_o aqua_fw-la fortis_fw-la the_o lunar_a corpuscle_n be_v so_o disjoin_v and_o suffer_v such_o a_o comminution_n as_o they_o do_v in_o crystal_n of_o lune_fw-fr the_o metal_n thus_o prepare_v and_o bring_v with_o its_o saline_n additament_n into_o a_o new_a texture_n will_v easy_o enough_o dissolve_v not_o only_o in_o water_n but_z as_o i_o have_v try_v in_o well_o

those_o of_o copper_n make_v with_o aqua_fw-la fortis_fw-la the_o last_o disposition_n to_o corrosibility_n consist_v in_o such_o a_o cohesion_n of_o the_o part_n whereof_o a_o body_n be_v make_v up_o as_o be_v not_o too_o strict_a to_o be_v superable_a by_o the_o action_n of_o the_o menstruum_fw-la this_o condition_n though_o of_o kin_n to_o the_o former_a be_v yet_o somewhat_o differ_v from_o

what_o have_v be_v say_v it_o may_v seem_v probable_a that_o as_o i_o former_o intimate_v the_o corrosibility_n of_o body_n be_v but_o a_o mechanical_a relation_n result_v from_o the_o mechanical_a

that_o it_o be_v upon_o the_o score_n of_o the_o specific_a gravity_n of_o a_o body_n and_o not_o bare_o upon_o the_o action_n of_o the_o precipitant_n that_o a_o aggregate_v or_o a_o convention_n of_o particle_n do_v rather_o fall_v to_o the_o bottom_n than_o rise_v to_o the_o top_n for_o though_o the_o agent_n that_o procure_v the_o coalition_n make_v the_o cluster_n of_o particle_n become_v

here_o i_o must_v not_o decline_v take_v notice_n of_o a_o phaenomenon_n that_o sometime_o occur_v in_o precipitation_n and_o at_o first_o sight_n may_v seem_v contrary_a to_o our_o doctrine_n about_o they_o for_o now_o and_o then_o it_o happen_v that_o after_o some_o drop_n of_o the_o precipitant_n have_v begin_v a_o precipitation_n at_o the_o top_n or_o bottom_n of_o the_o solvent_a one_o shake_v the_o vessel_n that_o the_o precipitant_n may_v be_v the_o soon_o diffuse_v through_o the_o other_o liquor_n but_o then_o they_o be_v quick_o surprise_v to_o find_v that_o instead_o of_o hasten_v the_o complete_a precipitation_n the_o matter_n already_o precipitate_v disappear_v and_o the_o solvent_a return_n to_o be_v clear_a or_o as_o to_o sense_n as_o uniform_a as_o it_o be_v before_o the_o precipitant_n be_v put_v into_o it_o but_o this_o phaenomenon_n do_v not_o at_o all_o cross_a our_o theory_n for_o when_o this_o happen_v though_o that_o part_n of_o the_o solvent_a to_o which_o the_o precipitant_a reach_n be_v disable_v for_o reason_n mention_v in_o this_o discourse_n to_o support_v the_o dissolve_a body_n yet_o this_o quantity_n of_o the_o precipitant_n be_v but_o small_a in_o proportion_n to_o the_o whole_a bulk_n of_o the_o solvent_a and_o therefore_o when_o the_o agitation_n of_o the_o vessel_n disperse_v the_o cluster_n of_o loose_o concrete_v particle_n through_o the_o
