The magnetization and correlation functions of the two-impurity Anderson model are calculated. When the exchange coupling, J, is larger than the critical value, Jc, found by Jones et al., the uniform magnetization curve has an inflection point at which the coefficient of specific heat diverges. The staggered magnetization under the staggered field remains small even at J = Jc.
