Note.—The letter m affixed to a page number signifies the middle third of the page; the letter b signifies the bottom third of the page; no letter being affixed, the top third of the page is referred to.
Hyphenation is mostly consistent. The word ‘representation’ is frequently given as ‘re-presentation’, as a technical term. Where the hyphen occurs at a line break, it is retained or removed based on other instances of the word in the text.
Errors deemed most likely to be the printer’s have been corrected, and are noted here. The references are to the page and line in the original.
