Using the data by Geyer et al. (1983) and by White and Shawl (1987) it has been looked for the dependence of the ellipticity of Galactic globular clusters on luminosity. There is evidence that the moderate bright objects are the roundest, while the most luminous as well as the weaker globulars are more flattened, on the average.
