PREFACE

This book and the accompanying map is chiefly intended for the use of
lunar observers, but it is hoped it may be acceptable to many who, though
they cannot strictly be thus described, take a general interest in
astronomy.

The increasing number of those who possess astronomical telescopes, and
devote more or less of their leisure in following some particular line of
research, is shown by the great success in recent years of societies,
such as the British Astronomical Association with its several branches,
the Astronomical Society of the Pacific, and similar institutions in
various parts of the world. These societies are not only doing much in
popularising the sublimest of the sciences, but are the means of

science, is becoming every year more and more specialised; and among its
