Abstract
THE constitutional formula tentatively suggested by Butenandt1 for the hydrocarbon C18H14 obtained by him from ketohydroxy-œstrin (follicular hormone) is closely related to the new constitutional formula of sterols and bile acids previously advanced by Rosenheim and King.2 The applicability of this formula to the basic ring system of ketohydroxy-œstrin and pregnandiol (see Bernal3) was, indeed, expressed in our preliminary note, and the work of Marrian and Haslewood4 and that of Butenandt (see above) supplies welcome experimental evidence in its favour.
