FROM THE PREFACE
Fifteen years have elapsed since the original publication of the present
work; and fifteen years count as a long spell of time where sidereal
research is in question. In preparing the Second Edition, accordingly, I
have introduced extensive modifications. Considerable sections of the
book have been recast, and all have been thoroughly revised. New
chapters have been inserted, old ones have been in large part
suppressed. Drastic measures of reform have, in short, been adopted,
with results that certainly import progress and (it is hoped) constitute
improvements. Most of the illustrations are entirely new; and I am under
great obligations for the use of valuable photographs and drawings,
among others, to Sir. David Gill, F.R.S., to Professor Hale and the
University Press of Chicago, to the Rev. W. Sidgreaves, S.J., to
Professors E. C. Pickering, Campbell, Barnard, and Frost, and to Dr. Max
Wolf of Heidelberg.
"The work was admirable from the first, imparting the best
knowledge of a decade and a half ago; now it retains its high
quality by incorporating the newer knowledge."--_The Guardian_.
"It has the remarkable feature of combining extraordinary profusion
of precise information with an elegance of literary style quite
unusual in scientific authors."--_The Academy_.
