Letter from [William Thomson, Lord] Kelvin, The University, Glasgow, to [Joseph] Larmor He thanks Larmor for the kind letter concerning the Mathamatical Society. He refers to [Wolfgang] Sellmeier and [Eduard] Ketteler, the latter coming onto the scene much later. H.A. [Hendrik Antoon] Lorentz seems adrift from Sellmeier's theory and he wonders if Larmor has looked into Lorentz's dynamics, since he appears to prefer Lorentz to Sellmeier. 21 October 1898
