• Highly purified β-1-monoglycerides from Nihon Glycerides Co. Ltd. was used for taking powder X-ray patterns of them. The results are as follows : <BR>1) Nearly hexagonal packing which was proposed in the previous paper<SUP>1)</SUP> explaining the existence of the short spacings for the β-1-monoglycerides of Riken Vitamin Co. Ltd. has also been applied to the short spacings of the specimens used in this paper, and the best fits are obtained between observed short spacings and calculated ones.<BR>2) Especial attention has been given to the extraordinary strong X-ray intensity of every (00 <I>n</I>+5) spacing, then the model which is constructed to describe the mass distribution of the chain molecule along its axis has been proposed by assuming that the two glycerol radicals in a double molecule are arranged in alignment with the acid chain, and the intensity ratios of (00 <I>n</I>+4), (00 <I>n</I>+5) and (00 <I>n</I>+6) are calculated based upon the model. The calculated intensity ratios are in fair accord with the observed ones, considering that the length of the gap between two successive double molecules increases slightly with carbon number.
