Scientific paper

ESO and AAT observations are combined so as to estimate O and N abundances of thirteen H II regions in the nuclear region, bar and arms of the barred spiral, hot-spot galaxy NGC t365 which has recently been found to have a Seyfert nucleus. In agreement with an earlier result based on a smaller data sample, the radial abundance gradient is quite small. The behavior of NGC 1365 in this respect is compared with that of a few other galaxies of similar morphological type but without a bar.
