Abstract
THE star Oeltzen, 17681, whose spectrum was announced by me to consist mainly of a yellow and blue band (NATURE, vol. xxii. p. 483), proves to belong to the same class as the three stars in Cygnus discovered by Wolf and Rayet in 1867 (Comptes rendus, vol. lxv. p. 292). A curious feature of these spectra is that they resemble each other without being identical, the relative brightness of the lines being very different. A further study of them is much to be desired.
