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

The authors show, in NGC 4736, that the bulge indicates strong and radially variable ellipticity, evidence of star formation, and outflow, while the bulge of the non-starburst galaxy NGC 5033 gives no evidence of peculiar or variable ellipticity.
