to_o produce_v a_o intense_a cold_a both_o of_o they_o act_v on_o it_o together_o shall_v produce_v the_o contrary_a quality_n but_o the_o reason_n i_o have_v to_o expect_v the_o success_n i_o meet_v

some_o unheeded_a circumstance_n may_v promote_v or_o hinder_v the_o artificial_a production_n of_o cold_a by_o particular_a agent_n but_o which_o will_v seem_v more_o strange_a some_o unobserved_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

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

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

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

because_o those_o volatile_a particle_n add_v much_o less_o of_o weight_n to_o the_o little_a concretion_n which_o compose_v the_o precipitate_v powder_n upon_o instance_n of_o this_o kind_n many_o
