Inconsistent, archaic and unusual spelling, hyphenation and capitalisation have been retained, except as mentioned below. This includes proper and geographical names.

Depending on the hard- and software used, not all elements may display as intended. Some tables are best viewed in a wide browser window.

Index: the occasional error in the order of entries has not been corrected.

For the illustrated versions: Where the quality of the illustration in the source document permits and where the visibility of details in or the legibility of the illustration requires, larger versions of illustrations have been provided. Availability of these larger illustrations depends on the version used.

Page 100, Fig. 27, Menhir (A): the reference letter is missing from the illustration.

Page 101, Carnac-Leomariaquer: probably Carnac-Locmariaquer (as on Page 38).

Footnote [124], table Chichen Itza, last line: the E. or W. is missing in the source document.

Changes made

Illustrations and tables have been moved out of text paragraphs; footnotes were moved to the end of the chapter. Some tables have been re-arranged. Ditto marks have occasionally been replaced with the dittoed text.

Some obvious minor typographical and punctuation errors have been corrected silently; some minor formatting inconsistencies have been standardised silently. Some Greek accents and diacritics have been ignored.

Texts in dotted rectangles are not present in the source document, but have been transcribed from the illustrations where these may not provide sufficient visible detail.

Page 90, Fig. 24: reference letters A, B, C and D inside the illustration have been enlarged for better visibility.

Page 173, first table: 19° 51' E. changed to N. 19° 51' E.

Page 220: footnote marker [65] inserted after Rhys where it seems to fit best (lacking in source document).
