Excerpt from The Moon: A Summary of the Existing Knowledge of Our Satellite, With a Complete Photographic Atlas

After the perusal of this volume the question may perhaps be asked how it is that anything new could have been discovered in regard to so conspicuous an object as the Moon - fan object that must have been constantly observed by the generations of astronomers already passed, many of whom were provided with far larger and more costly instruments than those used by the author.

The answer is a comparatively simple one. For many researches in astronomy, such as the study of faint stars, the separation and measurement of close doubles, the study of their spectra, etc., a telescope furnished with a large objective or lens is the paramount consideration. On the other hand, for planetary and lunar research the all-important consideration is a steady atmosphere. Such an atmosphere is found only in low latitudes, far from the great anti-cyclones of more northern regions. The earlier astronomers located their observatories either in high northern or high southern latitudes, thereby avoiding the very regions where the best results would 'have been obtained.
