The discoverer of Nova Aurigæ is the Rev Thomas D. Anderson of Edinburgh, D.Sc. in Classical Philology. Dr Anderson is “almost certain” that he saw the star at 2 a.m. on January 24 of this year; it was then slightly brighter than χ Aurigæ. Unfortunately, he mistook it for 26 Aurigæ, which it precedes by about 6m 39s, merely remarking to himself that the star was brighter than he had previously thought it to be. Twice in the following week he made the same observation at about the same hour of the night. At last, on the morning of January 31, it flashed upon him that, after all, the star was not 26 Aurigæ, and that 26 Aurigæ had a much greater right ascension. He consulted a small star-map, and the discovety was made. Regretting that he had not earlier compared the map with the heavens, and thinking that the star might be well known to astronomers, Dr Anderson wrote an anonymous postcard to me on the same morning bearing the words:—“Nova in Auriga. In Milky Way, about two degrees south of χ Aurigæ, preceding 26 Aurigæ. Fifth magnitude, slightly brighter than χ.” I may add that Dr Anderson's plant consists of a small hand spyglass adapted to astronomical purposes by removing the front pair of lenses from the eyepiece. In this state it magnifies about ten times, and, of course, gives inverted images. Dr Anderson hopes that amateurs, although provided with only the most modest appliances, may, by his unexpected success, be induced to persevere in their observations.
