Abstract
IN continuation of the accurate dilatometric investigation of ammonium chloride carried out by Prof. A. Smits and Miss C. H. MacGillavry1 in the neighbourhood of the well-known transition point at 30°, ammonium bromide has been studied by them and by the present writer in the neighbourhood of the analogous transition point at 39°. In connexion with these experiments, which have not yet been finished, these ammonium salts, especially ammonium bromide, have been investigated with X-rays by me. By arrangement with Prof. Smits, the results of these latter experiments are described here.
