Chapter I: Front Matter

Transcriber’s notes:

In this transcription, paired _underscores_ denote _italicised text_ and =equal= signs indicate bold text.

Footnotes are located below the relevant paragraphs.

The text contains some typographic characters that might not display correctly with all viewing devices. If some of the characters look abnormal, first ensure that the device’s character encoding is set to Unicode (UTF-8). The default font might also need to be changed to a Unicode font such as Arial Unicode MS, DejaVu, Segoe UI Symbol or FreeSerif.

Some pages contain alphabet letters displayed in bold sans-serif font, but some browsers or viewing devices may display them with a serif font.

The following spelling errors have been corrected silently:
pecularities —> peculiarities
indentification —> identification
classfication —> classification.

Inconsistent hyphenation (e.g. fingerprint, finger-print, finger print) remains as in the original text, as does the inconsistent use of em dashes in the index.

A few illustrations have been relocated nearer to the relevant text, and their page references adjusted appropriately in the list of illustrations.
