  Various authors have shown the occurence of naked singularities and black
holes in the spherical gravitational collapse of inhomogeneous dust. In a
recent preprint, Antia has criticised a statement in a paper by Jhingan, Joshi
and Singh on dust collapse. We show that his criticism is invalid. Antia shows
that in Eulerian coordinates a series expansion for the density of a collapsing
Newtonian fluid can have only even powers. However, he has overlooked the fact
that Jhingan et al. have actually used Lagrangian (comoving) coordinates, and
not Eulerian coordinates. As we show, in Lagrangian coordinates there is no
restriction that the density have only even powers and hence his criticism is
invalid. We also point out that an earlier claim by Antia on the instability of
strong naked singularities in dust collapse is not supported by any concrete
analysis, and is hence incorrect.
