Incomplete letter from [George Francis Fitzgerald], 7 Ely Place, to [Joseph] Larmor Fitzgerald considers the question of what is proved, rather than what is possible, thinking that [Ludwig] Boltzmann deals with likelihoods and has not advanced things by much. Larmor's statement about oxygen and nitrogen neither absorbing nor radiating, and that the atmosphere would be cold but for dossiciation in aqueous vapour is nice, but wrong, and Fitzgerald discusses this. He makes 'an extreme suggestion'which he has not time to consider, but scribbles down what comes into his mind. He cannot see why dissociation is outside usual investigation. The amount of dissociation in most bodies is too small for the theory. He discusses his own inconsistency in objecting and assuming equal partition of energy. Fitzgerald has been attempting to prove to [Samuel] Tolver Preston that he is assuming an impossible temperature equilibrium between Le Sage's corpuscles and the earth matter. 11 February 1895
