The inequality method of determining signs of Fourier coefficients is discussed from the point of view of the average sizes of the coefficients. It is shown theoretically and confirmed empirically that for crystals containing atoms of approximately t

and n = 4. The planar amide groups in biuret have normal dimensions and are slightly inclined and trans to each other, with an internal hydrogen-bond. The biuret molecules lie in buckled sheets parallel to (100), one molecule being joined to each of

A study was made to test the notion that powder data for structure determinations would be more useful if photographs were made with as many different consecutive K alpha wavelengths as possible so that as much of the diffraction pattern as possible

Banerjee has given a linear relationship between certain structure factors, Fhkl, of a crystal which may be useful in determining their signs. His equation is applicable only to crystals containing but one kind of atom. In this note a similar equatio
