         and yellow inks are largely made from aniline dyes.
         Indelible ink is usually a weak solution of silver
         nitrate, but carbon in the form of lampblack or India
         ink, salts of molybdenum, vanadium, etc., are also
         used. Sympathetic inks may be made of milk, salts of
