This paper examines the possibility of recovering quantitative information on chromospheric velocity fields from high resolution (lambda/Delta lambda of about 100,000) spectrograms of the Ca II H and K resonance lines. A qualitative discussion of the observed features is given in terms of a schematic theory of line formation in the case of

The paper presents a set of CCD images of four Galactic bulges, taken in the I photometric band under very good imaging conditions, with the Taurus camera on the 4.2-m William Herschel Telescope. As well as showing calibrated isophotes, the results of ellipticity analysis are given, which bring out a clear dichotomy between two of the bulges, where
