Observations of the nuclei of the Seyfert galaxies NGC 1068 and MKN 335 were performed with an angular resolution of 0.025 arcsec using the TV speckle interferometer of the Special Astrophysical Observatory 6-m telescope. Image recording was carried out in narrow spectral bands (at a wavelength in the range of 130-350 A) centered on the forbidden O III 5007 A and H-alpha 6563 + forbidden N II 6548, 6583 A lines in the galaxy spectra. Profiles of the autocorrelation functions of NGC 1068 obtained in the forbidden O III line agree on a scale of less than or equal to 0.5 arcsec with radio data, revealing the presence of a triple source in the inner subsecond region.
