Abstract
We discuss recent extended x-ray-absorption fine-structure work of Sayers, Stern, and Lytle. We note that their use of distance variation to rule out crystallinity is not valid and that the variation they find is also available from diffraction data. Finally, contrary to statements of Sayers, Stern, and Lytle, we have not described glasses in terms of microcrystals. Our radial distribution analysis reveals ordering in some glasses which resembles in part but cannot be equated to that in crystals.
