THIS is the fifteenth impression of this book since its inception in 1868. Under Dr. Steavenson's revision, a number of necessary corrections and additions have been made with the view of continuing its former usefulness. New illustrations have been substituted throughout. It may be mentioned that the book is essentially one for the amateur possessing a telescope which he is prepared to use. He will then find in this little publication an excellent guide to the many objects of interest within reach of modest telescopic means, together with a simple account of the construction of his instrument and valuable hints for its successful use. The book is of pocket size, and the type is clear. There are, however, a few misprints, as on pp. 59, 70, and 107. A brief note on the nomenclature of the stars, or a reference to the British Astronomical Association Handbook for 1924 (in which all star catalogues are briefly described), would have been helpful to the beginner. From a cursory glance at the pages, the would-be purchaser might be inclined to object to the price, but its worth will be readily admitted by a purchaser who, with its aid, has spent some very profitable half-hours with his telescope.
