with_o it_o it_o will_v continue_v still_o a_o acid_n salt_n and_o oppose_v to_o alkali_n but_o to_o clear_v up_o this_o point_n the_o better_a we_o must_v consider_v as_o nice_o as_o may_v be_v the_o

reasonable_o conjecture_v that_o a_o alkali_n be_v a_o terrestrial_a and_o solid_a matter_n who_o pore_n be_v figure_v after_o such_o a_o manner_n that_o the_o acid_n point_v enter_v into_o they_o

find_v more_o or_o less_o resistance_n do_v cause_n a_o strong_a or_o weak_a ebullition_n so_o we_o see_v the_o effervescency_n that_o happen_v in_o the_o dissolution_n of_o coral_n be_v very_o much_o mild_a than_o that_o in_o the_o dissolution_n of_o silver_n there_o be_v as_o many_o different_a alkali_n as_o there_o be_v body_n that_o have_v different_a pore_n and_o this_o be_v the_o reason_n why_o a_o acid_n will_v ferment_n one_o strong_o and_o another_o not_o at_o all_o for_o there_o must_v be_v a_o due_a proportion_n between_o the_o acid_n point_n and_o the_o pore_n of_o the_o alkali_n the_o nature_n of_o alkali_n be_v thus_o establish_v there_o will_v be_v no_o need_n of_o fly_v to_o a_o imaginary_a salt_n in_o plant_n for_o explication_n of_o the_o effervescency_n and_o it_o will_v be_v easy_o conceive_v that_o if_o a_o alkali_n salt_n be_v full_a of_o a_o terrestrial_a matter_n that_o render_v it_o porous_a like_o other_o alkali_n it_o must_v cause_v a_o ebullition_n that_o which_o i_o say_v speak_v of_o volatile_a salt_n may_v here_o be_v add_v that_o the_o igneous_a particle_n break_v out_o through_o the_o pore_n of_o the_o alkali_n salt_n where_o they_o become_v imprison_v in_o the_o calcination_n do_v much_o contribute_v to_o the_o raise_v this_o effervescency_n and_o real_o when_o the_o acid_n spirit_n of_o vitriol_n or_o aquafortis_n be_v cast_v upon_o a_o alkali_a salt_n there_o happen_v as_o strong_a a_o ebullition_n as_o when_o this_o liquor_n be_v fling_v into_o the_o fire_n the_o fermentation_n that_o happen_v to_o dow_n to_o new_a wine_n and_o such_o like_a thing_n differ_v from_o that_o i_o now_o speak_v of_o in_o that_o it_o be_v more_o gentle_a and_o slow_a this_o be_v cause_v by_o the_o acid_n natural_a salt_n contain_v in_o they_o which_o expand_v and_o exalt_v itself_o by_o its_o motion_n do_v rarify_v and_o raise_v up_o the_o grosser_n and_o sulphurous_a part_n that_o endeavour_v to_o allay_v its_o motion_n from_o whence_o it_o come_v that_o the_o matter_n swell_v up_o the_o reason_n why_o a_o acid_n do_v not_o make_v sulphurous_a thing_n ferment_n with_o so_o
much_o noise_n and_o suddenness_n as_o alkali_n be_v because_o that_o oil_n consist_v of_o pliant_a part_n that_o yield_v and_o make_v no_o resistance_n to_o the_o point_n of_o acid_n as_o a_o piece_n of_o wool_n or_o cotton_n will_v yield_v and_o give_v way_n to_o needle_n that_o be_v thrust_v into_o it_o thus_o methinks_v two_o sort_n of_o fermentation_n may_v be_v admit_v of_o the_o one_o of_o a_o acid_n with_o a_o alkali_n which_o may_v be_v call_v ebullition_n and_o the_o other_o when_o a_o acid_n do_v by_o little_a and_o little_o rarify_v some_o softish_a matter_n as_o dow_n or_o clear_a and_o sulphurous_a as_o must_v cider_n and_o all_o other_o juice_n of_o plant_n this_o last_o sort_n may_v rather_o be_v call_v fermentation_n it_o be_v further_a remarkable_a that_o the_o acid_n and_o alkali_n do_v so_o destroy_v one_o another_o in_o their_o conflict_n that_o when_o as_o much_o acid_n have_v be_v by_o degree_n pour_v as_o be_v necessary_a to_o penetrate_v the_o alkali_n in_o
