The morphological scheme devised by Hubble and followers to
classify galaxies has proven over many decades to be quite
effective in directing our quest for the fundamental pa rameters
describing the extragalactic manifold. This statement is however
far more true for spirals than for ellipticals. Echoing the
concluding remarks in Scott Tremaine's sum mary talk at the
Princeton meeting on Structure and Dynamics of Elliptical Galaxies,
"the Hubble classification of spirals is useful because many
properties of spirals (gas con tent, spiral arm morphology, bulge
prominence, etc. ) all correlate with Hubble time. By contrast,
almost nothing correlates with the elliptical Hubble sequence El to
E7. " During the last few years much effort has been put into the
search for a more meaningful classification of ellipticals than
Hubble's. Concomitantly, forwarded by some provocative conjectures
by R. Michard, the classical question of whether E galaxies form a
physically homogeneous family has been brushed up once more.
Results of these and other parallel studies look rather promising
and point to suture part of the dichotomy between ellipticals and
disk galaxies which had become popular in the early eighties, owing
to dynamical arguments. At the same time it appears more and more
clear that, besides the usual genetic varieties of galaxies,
products of environmental evolution must also be contemplated in
building our modern picture of the "reign of galaxies" . The above
considerations prompted us to solicit Prof."
