Transcriber’s Note

Obvious typographical errors were corrected. The spelling of French words has been made consistent. Also made consistent were those words which appear as hyphenated, joined or as two individual words (for example, first class to first-class and some one to someone). Other corrections were made where inconsistent or incorrect spellings were used in the publication. Where the inconsistencies occur in publication titles or quoted text passages, they were left as published.

Some of the entries in the INDEX appear to be missorted alphabetically. They were left as printed. On [page 114], one line ends with “modifica-” and it is assumed “tion” was left off the next line.

Whole and fractional parts of numbers are displayed as 45⁄8 or as a decimal number. In several of the advertisements, another type of ‘fraction’ is displayed to represent shillings and pence: 1/11⁄2 is one shilling, one and one-half pence and 1/- is 1 shilling and no pence.
