Abstract The quasi-chemical approximation of Guggenheim for calculating the thermodynamic properties of the Ising model is discussed. The Ising model is where a system of atoms is arranged on a lattice with simple nearestneighbor interactions. This model provides a more or less realistic description of many physical systems. For convenience a calculation is made of a mixture of two kinds of atoms, A and B, the forces between the atoms being such that a (nearest- neighbor) AB pair has an energy larger by an amount epsilon than the average of an AA or BB pair. The method was chosen because it provides a sequence of approximations which is believed to converge to the exact solution. (N.W.R.)
