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

to_o exalt_v all_o the_o salt_n which_o be_v the_o reason_n that_o less_o fix_a salt_n be_v to_o be_v find_v in_o animal_n than_o plant_n as_o for_o what_o many_o do_v say_v that_o choler_n cause_v

methinks_v here_o be_v no_o need_n at_o all_o of_o suppose_v a_o alkali_a salt_n that_o ferment_n with_o the_o acid_n of_o this_o liquor_n as_o many_o suppose_v for_o explicate_v this_o effect_n since_o if_o we_o consider_v but_o the_o natural_a composition_n of_o milk_n we_o shall_v find_v nothing_o but_o a_o creamy_a substance_n swim_v on_o the_o serum_n and_o mix_v only_o superficial_o with_o it_o by_o the_o intermixture_n of_o some_o salt_n so_o that_o it_o be_v in_o a_o fit_a state_n of_o separation_n as_o soon_o as_o the_o salt_n gain_v a_o little_a more_o motion_n than_o it_o have_v whether_o it_o be_v by_o fermentation_n or_o by_o increase_a its_o activity_n by_o a_o acid_n of_o its_o own_o nature_n thus_o when_o the_o heat_n of_o the_o summer_n or_o fire_n have_v stir_v

always_o the_o cause_n of_o coagulation_n in_o milk_n there_o be_v no_o great_a likelihood_n that_o a_o salt_n of_o the_o same_o nature_n shall_v be_v the_o instrument_n of_o unite_n the_o several_a
