Transcriber’s Notes

Depending on the hard- and software used and their settings, not all elements may display as intended; some of the larger tables are best viewed on a wide screen in a wide window.

Inconsistent spelling, hyphenation, lay-out and use of accents and thousands separators have been retained except as listed below.

The (inconsistent) use of spaces, underscores, hyphens etc. to indicate blanks where names, data etc. need to be inserted has not been standardised.

page 4, Dr. Ackland: possibly Henry Acland.

page 137, 855 décicarcel-cubes: probably the decimal point is missing.

page 372, Ranson’s: should possibly be Ransom’s (cf. Table of Contents) or vice versa.

Index: not all items are given in alphabetical order, this has not been corrected.

Changes made:

Footnotes have been moved to the end of each chapter.

Some obvious minor punctuation and typographical errors have been corrected silently.

Vide has been standardised to Vide.
