A consistent Fermi-liquid theory of heavy-electron compounds at low temperatures is microscopically derived from the Kondo-lattice model. Interactions between the heavy quasiparticles are mediated by fluctuations of effective valence-conduction hybridization parameters. The computed values of the Wilson ratio, the T³lnT term in the specific heat, and the T² coefficient of the low-temperature resistivity are in agreement with systematic experimental trends.
