the_o forementioned_a experiment_n which_o produce_v the_o coagulum_fw-la upon_o the_o mixture_n of_o spirit_n of_o wine_n and_o urine_n be_v difficult_a to_o be_v perform_v since_o it_o be_v a_o hard_a matter_n to_o obtain_v spirit_n fine_a enough_o for_o such_o a_o purpose_n i_o shall_v subjoin_v a_o more_o easy_a one_o which_o be_v that_o if_o spirit_n of_o salt_n be_v add_v to_o the_o white_a of_o a_o egg_n beat_v to_o a_o certain_a thinness_n the_o mixture_n will_v be_v so_o much_o coagulate_v as_o not_o to_o afford_v the_o least_o drop_n though_o the_o glass_n in_o which_o the_o

effect_n of_o the_o particular_a texture_n of_o its_o saline_n part_n since_o other_o salt_n which_o be_v account_v cool_a have_v the_o same_o effect_n and_o not_o only_o so_o but_o though_o spirit_n of_o wine_n will_v coagulate_v the_o whites_n of_o egg_n yet_o it_o have_v not_o that_o effect_n upon_o the_o serum_n of_o man_n blood_n though_o the_o heat_n of_o the_o fire_n will_v coagulate_v the_o one_o as_o well_o as_o the_o other_o but_o it_o do_v not_o only_o experimental_o appear_v that_o a_o consistent_a body_n may_v result_v from_o a_o mixture_n of_o two_o fluid_n but_o also_o that_o a_o fluid_a may_v undergo_v such_o a_o alteration_n as_o to_o be_v change_v into_o two_o consistent_a body_n and_o this_o be_v evident_a in_o distil_a salad_n oil_n since_o the_o substance_n draw_v over_o be_v devoid_a of_o fluidity_n as_o well_o as_o that_o which_o remain_v behind_o and_o to_o make_v it_o appear_v that_o the_o reason_n of_o it_o be_v the_o bare_a result_n of_o texture_n and_o the_o hook_a figure_n of_o its_o part_n if_o we_o add_v to_o the_o oil_n a_o sufficient_a quantity_n of_o common_a salt_n it_o afford_v a_o oil_n which_o fall_v in_o drop_n into_o the_o
