The Nature of X-Rays


PROF. BRAGG in a recent letter (NATURE, April 16) credits me with the admission that the experiments I made on the intensity of secondary (scattered) X-rays are not so contrary to the neutral pair theory as I at first supposed. Will you permit me to correct this by saying that all the evidence I have obtained has verified the ether pulse theory in a more striking way than I ever anticipated, and I cannot think of a single experimental result obtained in researches on secondary X-rays which gives any support to his theory?
