- Winnecke 4 (also known as Messier 40 or WNC 4) is an optical double star consisting of two unrelated stars in a northerly zone of the sky, Ursa Major.
- Lake Elmo, Washington County, Minnesota, was named by A. B. Stickney, now of St. Paul, Minn.,, from a nearby lake, that had been named from the novel “St. Elmo.” The town was formerly called Oakdale from the many Black Oak (Quercus nigra) trees that grow hereabouts. It is not known where the novelist found the name for her book, but it is supposed she “evolved it out of the depth of her own consciousness.” She did not get it from that corposant known as “St. Elmo’s fire,” which was named for St. Elmo, the patron saint of navigators.
