Minor errors and inconsistencies in punctuation and hyphenation have been silently corrected.
Some illustrations have been relocated a short distance within the text.
Original page numbers have been retained in the index.
Greek letters, used to identify stars, are replaced with the full name of the Greek letter, e.g. alpha. Upper case Greek letters are shown by capitalising the initial letter, e.g. Sigma 1126
A caret (^) is used to represent superscripts, e.g. nu^1 and nu^2
The following minor corrections have also been made:
p28: Sigma 629 is not shown on Map No. 1. The location of _m_ Orionis is marked as Sigma 696. This inconsistency has not been corrected.
p54: "for colors" has been corrected to "four colors".
p68: "1,065,790,250,000,000" has been corrected to "1,065,702,500,000,000".
p163-164: "magnical" has been corrected to "magical".
