had turned out as fine a piece of work as has appeared in fifty years, so long will English physics remain preeminent.The first chapter reviews briefly the older theories of X-rays and presents Laue's dis- covery and photographs.The second presents the Bragg theory of the diffraction of X-rays, the third describes in detail the Bragg X-ray spectrometer, the fourth is a brief account of the properties of X-rays.The fifth merely de- scribes crystal structure, little known to most physicists, and the sixth presents our present knowledge of X-ray spectra, and includes an admirable report on Moseley's work.The re- maining Si1x chapters present the Bragg an- alysis of crystal structure made by means of their spectrometer.Few books have ever appeared which repre- sent in so high a degree the creative work of the authors themselves.
