Paper, 'On the theory of electrodynamics, as affected by the nature of the mechanical stresses in excited dielectrics' by Joseph Larmor Larmor writes: 'A theory of electrodynamics was first precisely developed by Maxwell, which based the phenomena on Faraday’s view of the play of elasticity in a medium, instead of the conception of action at a distance, by means of which the mathematical laws had been primarily evolved.'
