RICHTMYIR It is possible that the crystalline 8-D-altrose is a furanose form. Preliminary meaaurements of the extremely rapid change of rotation which occurs within the first three minutes after altrose is dissolved in water at 20" have indicated an initial highly negative rotation, although the extrapolated value [ ~ ] D ~ O - 69" is necessarily uncertain.
