The temperature dependence of resistivity is fitted well by a generalized Bloch-Gruneisen equation with a Debye temperature of 1050 K. The Seebeck coefficient is given by the sum of a diffusive and a phonon drag term and the behavior in the temperature region $% Tc<T<0.1\\Theta_{R}$ follows a relationship $AT+BT^{3}$ where the two terms are proportional to the electron and to the phonon specific heat, respectively.
