The long sought-after remnant of the celebrated 1885 supernova, commonly known as S Andromedae, which occurred in the nuclear bulge of M31, has been discovered. The detection in Fe I absorption suggests that: (1) the remnant contains appreciable iron-rich ejecta consistent with a type I supernova classification, (2) the ejecta are still mainly cold and freely expanding, (3) S And's Fe I absorption-line profiles must be quite broad, and (4) S And probably occurred on the side of M31's bulge nearer to us. Future absorption-line observations of S And have the potential of becoming among the most informative observations ever taken of a type I supernova. 19 refs.
