From one spectrogram, in 1915, Pease and Adams obtained an observed
velocity of –12 km.” The image of N.G.C. 6572 is elliptical in form, the bright
central portion being 9” X 14", with the major axis of figure in position angle 0°.

Two of the above spectrograms were secured with the slit along the short axis,
i.e., on the line joining the two bright lobes and passing through the nucleus. The
nebular lines on these plates show no inclination of the lines as a whole, but their

Wright in 1901, comparing the H8 nebular line with the HB line from the hydrogen
tube, on a 3-prism spectrogram, obtained a radial velocity of +12.3 km. per
second; and from two 1-prism spectrograms, +6 km.” Hartmann in 1901 obtained
