Letter from Geo Fras [George Francis] Fitzgerald, 1 Windsor Terrace, Maalahide, to [Joseph] Larmor Fitzgerald considers himself captious, he meant the force between the salt and the charging water, explaining his defence of the statement regarding knowing force before solving the osmotic pressure problem. He criticises the clarity of work by [Johannes Diderik] van der Waals, [Ludwig] Boltzmann, and [Josiah] Willard Gibbs. Larmor's statement on solvent has 'cleared away the mist', making Fitzgerald feel stupid. He reports on jubilee sports at Malahide, and gives a brief postscript on induction, 23 June 1897
