Kerlick has obtained the unexpected result that the spin-spin contact interactions, which are characteristic of the Einstein-Carton-Sciama-Kibble theory of gravitation, are attractive for the case of a totally antisymmetric spin angular momentum density tau/sub i j k/ which, in particular, is appropriate for the Dirac field. Using our previous techniques, where the emphasis is on the use of Lagrangian densities as opposed to energy-momentum densities, we present a simple and explicit verification of this result.
