Transcriber’s Notes

Variant spelling and hyphenation are preserved as printed. Simple typographical errors were corrected.

In the printed book, ditto marks often indicated repeated text. In this e-book, [the repeated text is copied in full].

In the Measurements tables, [zeros were added around the decimal to align data].

In the indexes, only references within this volume are hyperlinked.

All transcriber’s notes are commented into the source code, like so: <!--TN: -->.
