We report on CTIO spectropolarimetry observations of these two Seyfert galaxies. NGC 1365 is a nearby galaxy (z=0.005) which has been variously classified as a Seyfert 2, Seyfert 1.8, NLS1, and a starburst-Seyfert. Our spectra suggests it is currently a Narrow-line Seyfert 1, with iron lines in the spectrum. It has a continuum polarization rising to about 1.5% in the blue, similar to that of other NLS1 galaxies such as IRAS~20181--2244.

NGC 3393 is a luminous southern Seyfert 2 galaxy at z=0.013. Our data show it has a hidden broad line region visible in the polarized flux.

Support from the NSF, NASA, the Center for Astrophysical Sciences at JHU, and FAPESP is gratefully acknowledged.
