Dielectric properties of a D-serine admixtured triglycine sulphate (TGS) crystal were studied on samples cut out from different sites in the crystal. The value of spontaneous polarization P_{s} measured on b-cuts was found to be independent of the site. Whereas the coercive field E_{c} values were higher for the samples cut out closer to the seed than for those cut out at the ends of the crystal along b axis. After rejuvenation the values of the bias field E_{b} increased in contrary to the effect observed in the pure TGS crystals. An exponentially decreasing dependence of the maximum permittivity ε_{max} on the site of the samples (b-plates) cut out along b axis from -b to +b positions, was obtained.
