On account of the increasing importance of the temperature factor in the theory of the analysis of crystal structure by means of X-ray reflection, and in view of the fact that no experimental work on the temperature effect has been published since the original preliminary investigation by Prof. W. H. Bragg in 1914, it is hoped that the present account will be of interest, in which the work of Bragg is extended to a variety of crystals and continuous temperature curves have been obtained ranging up to 950°C. Theories of the effect of temperature on X-ray reflection have been given by C. G. Darwin and P. Debye, and these agree in that the intensity of reflection— (1) Decreases as the temperature of the crystal increases; (2) Decreases more rapidly as the angle of reflection increases.
