In a recent letter to Nature F. London( 3 ) has called attention to a discontinuity in the derivative dC V / dT of the specific heat with respect to temperature which arises in a perfect Einstein-Bose gas at low temperatures. When discussing the properties of a perfect gas satisfying the Bose statistics, Einstein( 1 ) remarked that at low temperatures something resembling a condensed phase should appear. The temperature at which this condensation should begin is given by the equation where n is the number of particles of mass m per unit volume and the other symbols have their usual significance.
Fowler et al. (Sat,) studied this question.
