Transcriber’s Notes

Added periods between the dollar and cents in the tables on [page xvii] and [page xi].

The reprint that was used as the source for the ebook was flawed, and two missing words were added to the notes on [page l], from an alternate document: “to the [amount of] $20,000.”

Obvious typographical errors have been silently corrected. Variations in hyphenation and accents have been standardised but all other spelling and punctuation not mentioned here remains unchanged.

To aid readability on smaller devices, images of some of the more complex tables have been provided at the end of the book.
