IN connexion with a paper under the above title,1 Prof. W. N. Haworth has pointed out that the actual space formulæ of d-mannitol and i-dulcitol are:On uncoiling these to give zigzag or slightly spiral chains of the nature suggested by the dimensions of the unit cells, the projections of the chains on a plane perpendicular to the plane of the zigzag becomeThis involves the alteration in position of two hydroxyl groups per molecule in the models illustrated in the paper. These alterations do not affect materially the fundamental features of the respective unit cells, but they introduce interesting possibilities which will be discussed in a separate paper.
