Letter from Louis Trenchard More, University of Cincinnati, Cincinnati, Ohio, USA, to Joseph Larmor, Cambridge, England He sends an article lately published in the Philosophical Magazine, which tends to preclude 'the idea of mechanical strains being produced in matter by electric charges', confirming opinions expressed in Larmor's British Association address. He notes the general acceptance of [George Hermann] Quincke's experiment that glass alters in volume and length when electrified, and this was to be expected. This caused him to hesitate in going into print, but Larmor's work fortified him. He will experiment on the effect of mechanical pressure, the Kerr effect, in due course. 24 October 1900
