  We continue our study of the application of the conformal gravity theory to
galactic rotation curves. Previously we had studied a varied 111 spiral galaxy
sample consisting of high surface brightness galaxies, low surface brightness
galaxies and dwarf galaxies. With no free parameters other than galactic mass
to light ratios, we had found that the theory is able to account for the
systematics that is observed in the entire set of galactic rotation curves
without the need for any dark matter whatsoever. In the present paper we extend
our study to incorporate a further 27 galaxies of which 25 are dwarf galaxies
and provide updated studies of 3 additional galaxies that had been in the
original sample, and again without dark matter find fully acceptable fits, save
only for just a few galaxies that we find to be somewhat troublesome. Our
current study brings to 138 the number of rotation curves of galaxies that have
been accounted for by the conformal gravity theory. Since one of the primary
ingredients in the theory is a universal contribution to galactic motions
coming from matter exterior to the galaxies, and thus independent of them, our
study reinforces one of the central concepts of the conformal gravity studies,
namely that invoking dark matter should be viewed as being nothing more than an
attempt to describe global physics contributions in purely local galactic
terms.
