This book provides an up-to-date and authoritative outline of our knowledge of the heavenly bodies—their distances, dimensions, masses, constitutions, temperatures, etc.—and explains the methods used by the astronomer for acquiring this knowledge. As far as possible anything except elementary mathematical treatment of the problems has been avoided in the text, with the exception of the chapter on Navigation. Where it has seemed desirable more difficult mathematical matters have been relegated to footnotes at the ends of chapters or to the Appendices which, however, are not essential for understanding the subjects outlined in the text.
