Abstract
THE large edition of Mr. Cottam's magnificent charts has met with a well-deserved success, and the smaller edition before us will doubtless be received in a similarly favourable manner. The thirty-six charts in the large edition measure 30 × 22 inches, and were projected on the scale of one-third of an inch to a degree of a great circle; the size in the reduced form is 15 × 12 inches, and the scale is one-half as great. In this handy size the charts will be sure to have a wide circulation among beginners in the study of astronomical science, and to possessors of the smallest telescope with alt-azimuth mounting they are invaluable. The road to an intimate knowledge of the stellar universe is considerably straightened by showing each constellation on a separate chart, whilst three key maps exhibit the relative positions of the various constellations, and will be extremely useful to show alignments over larger spaces than are included on the separate charts. Some notes on the constellations, in conjunction with an excellent introduction explanatory of various astronomical measurements and methods, enhance the value of the charts and help to render the work superior to any hitherto published.
Charts of the Constellations.
