The velocity dispersion of the stars in the nucleus of the Seyfert galaxy NGC 1068 was found to be 150plus-or-minus50 km s$sup -1$ from an Fe i absorption line in a spectrum obtained with an integrating television sensor. If the structural length R$sub 0$<140 pc in the nucleus and H=50 km s$sup -1$ Mpc$sup -1$, the mass within this radius is 14(+10, -8) times10$sup 8$ M/sub sun/ , and less if R$sub 0$approximately-greater-than140 pc. Strong interstellar H and K absorption lines superposed on the spectrum of NGC 1068 show that N (Ca ii) = (6plus-or-minus3) times10$sup 12$ cm$sup -2$ at b=-52degree in the halo of our galaxy. (AIP)
