At the present time, the relations between the specific heats are other thermodynamical properties of gases and vapours, and the devitions from the behaviour of the ideal gaseous substance in isotherm and adiabatic expansion, remain extremely obscure. The variation of the latent heat of a vapour, and of its saturation pressure, a generally expressed by purely empirical formulae, without theoretic foundation. Various equations, such as those of Van der Waals, are Clausius, have been proposed and have been very generally adopted represent some of the simplest of these relations, but owing to the complexity, and to the number of empirical constants involved, the utility is seriously limited, and the results to which they lead are some cases undoubtedly erroneous.
