be_v differ_v from_o spirit_n of_o urine_n and_o other_o spirit_n that_o be_v call_v volatile_a alcaly_n the_o question_n whether_o there_o be_v any_o difference_n between_o the_o spirit_n of_o

whether_o or_o no_o if_o the_o spirit_n of_o humane_a blood_n and_o other_o liquor_n abound_v like_o it_o in_o volatile_a alcaly_n be_v reduce_v to_o as_o great_a a_o purity_n as_o they_o can_v by_o

be_v wont_n to_o be_v think_v pure_a enough_o for_o medicinal_a use_n and_o be_v according_o employ_v by_o physician_n and_o chemist_n i_o think_v it_o very_o probable_a that_o there_o be_v some_o
