Abstract
IN a letter to NATURE of January 23 (p. 270) Prof. Bragg mentions the results of some experiments on rays from which he concludes that the ether pulse theory of rays is not tenable, but which support his theory that the rays consist of neutral pairs revolving in a plane containing their direction of translation. From the close resemblance of X-rays to rays he assumes that they also consist of neutral pairs. His reasoning seems to be that if the rays are ether pulses only, they should produce in any substance which they strike secondary kathode rays which come off equally in all directions, and if they do not the ether pulse theory cannot be correct.
