Abstract
The spectra of four FHB stars have been obtained at about 5 Å resolution between λ1200 and λ1900 with the International Ultraviolet Explorer (IUE). The intensity distributions of three of the stars match that of the "FHB distribution" in Huenemoerder et al. (1984). The coolest star of the four, HD 2857, has an ultraviolet distribution that drops off rapidly short of λ1750.
