Table of Contents, page 130: The Enigmas, Charades, Puzzles, &c., &c. do not actually start on this page (they start on page 2), but there are no more Pictured Puzzles and Word Play from this page on.
Page 49, Se Pierot or Lun: possibly an error for See Pierot or L’un or Le Pierot or L’un.
Page 60, No. LX: the description is confusing, as the puzzle consists of drawing the four dotted lines, and they are therefore not given.
Page 89 and 263, Pictured puzzle LXXXIX and solution: either the puzzle or the solution has been printed upside-down in the source document.
Page 114, ... as nearly as possible of the size and pattern ...: based on the size of the physical book (around 7″ or 18 cm tall), the boomerang’s width would be some 3″ or 7.5 cm.
Page 149, ... six single words: the solution provided gives five single words.
Page 205, Solution IX: the table as printed lacks values for Opposite pairs of short diagonals (of which there are four) and Such combinations as 482, 484, 472, 470 (of which there ought to be two in order to reach the given total).
Changes made
In the source document, jokes, riddles and puzzles may be split over multiple pages (for example, Word Play 5 may be found on page 7 (first part) and page 9 (second part)). In this e-text, the second part has been re-combined with the first, and references to the separate first and second parts have been deleted.
Some minor obvious typographical errors have been corrected silently. Similarly, minor discrepancies (such as the number of blanks or periods) have been rectified silently. Fractions (the forms x⁄y, xy and x-y all occur in the source document) have (bar a single exception) been standardised to x⁄y.
