Letter from G A [George Adolphus] Schott, Tygwyn, Aberhosan, near Machynlleth, to [Joseph] Larmor He has just sent a paper to the Royal Society with Larmor's covering letter and the meeting abstract. He thanks Larmor for the trouble he has taken. He thinks that Larmor is right in that damping can only be small for fine lines such as those photographed by the Braggs and others for x-rays. He makes two points about x-rays and gamma rays, thinking that large damping may be possible for hard gamma rays, and noting their origin. He has finished the analysis for the effect of damping, the numerical work being difficult, but he can see a small damping may produce comparatively big effects for short waves, although not enough to account for some results. 18 September 1919
