  <dc:title>Letter from C G [Charles Glover] Barkla, Littledene, Priestfield Road, Edinburgh, to Sir Joseph [Larmor]</dc:title>
  <dc:description>Thanking Larmor for his letter and copies of papers. Barkla's letter to Nature of 4 March might explain things more clearly. Part of the energy of a primary beam of x-rays traversing a substance is scattered and he has measured and allowed for this. Part is absorbed and the emission of each fluorescent x-radiation can be isolated and measured. He explains this from his first letter to Larmor and he gives formulae for the scattered and absorbed energy.   </dc:description>
