  We analyse long-slit spectra of four early-type galaxies which extend from ~1
to ~3 effective radii: IC1459, IC3370, NGC3379 and NGC4105. We have extracted
the full line-of-sight velocity distribution (in the case of NGC3379 we also
used data from the literature) which we model using the two-integral approach.
Using two-integral modelling we find no strong evidence for dark haloes, but
the fits suggest that three-integral modelling is necessary. We also find that
the inferred constant mass-to-light ratio in all four cases is typical for
early-type galaxies. Finally, we also discuss the constraints on the
mass-to-light ratio which can be obtained using X-ray haloes in the case of
IC1459, NGC3379 and NGC4105 and compare the estimated values with the
predictions from the dynamical modelling.
