Changes to the text (in the case of corrections to typographical errors) are listed at the end of the book.

On page 45, in the reference "Beccheri's Physica Subterranea, LipsiÆ, 1738 (with supplement), 8vo., 1681-80;", no satisfactory explanation of "1681-80" has been found. Note that the publication date of Physica Subterranea is 1669.

On pages 83 & 84 in the explanation of Plate III, a single quote is used to denote the decimal point: this convention has been retained.

From a Bust by Mr. James Loft, Sculptor, exhibited at the Royal Academy, 1867; and now in the Sculpture Gallery of the Crystal Palace, Sydenham.
