Abstract. We report various structural observations of monodisperse foams in the bulk, at surfaces, in cylinders and between glass plates. In general they tend to refute Matzke's assertion that even monodisperse foam is totally disordered. However, it appears that the tendency to order is quite limited in the bulk under normal circumstances. Small fragments are observed which correspond closely to the recently reported structure of Weaire and Phelan.
