PREFACE THE specific things undertaken in this book are: First, the presentation of a set of star-charts, ac- companying and illustrating the text, and containing the constellation figures, so that the reader may see those strange forms that the imaginations of men for thousands of years have drawn in the sky. The charts also contain all the stars that have received distinctive names, and with these all the other stars that the unaided eye readily perceives. The sixth- magnitude stars are visible to ordinarily good eyes, but they are inconspicuous. The charts are reduc- tions from Heis's Atlas Ctclestis. A chart of the southern sky has been added to cover the constellations not visible from our latitudes. Second, the march of the constellations across the sky, resulting from the annual revolution of the earth in its orbit, is followed from month to month, and they are presented in the text according to the times of their successive arrivals near the meridian, the north and south line of the sky. Of course they are not visible only when on or near the meridian; but some system must be followed in describing them, and this arrangement, recognizing the sequence of the months, and presenting them when, upon the whole, they are best placed for observation, seemed prefer- able to any other. The appearance of the constella- tions, as viewed with the naked eye, is described, their histories and mythologies are given, and the stories of their chief stars and star groups are detailed. For the convenience of those who have telescopes, some of the double stars and other interesting tele- . scopic objects in each constellation are described and their positions indicated. ...
