CAMBRIDGE: PRINTED BY JOHN CLAY, M.A. AT THE UNIVERSITY PRESS.
Transcriber’s Note
This text was prepared from materials kindly provided by the Internet Archive. There are a few changes from the appearance of the original text. In the original, footnotes are numbered consecutively on each page. The superscripted numbers for them are usually placed before, rather than after, punctuation marks. Ellipses are often used without any spacing. In the Exercises, the difference in font size between questions and sample answers is not always adhered to. The formatting of arguments and some proofs is not always copied exactly in this version.
I have put page numbers into the text in red. Footnotes are placed after the paragraphs to which they connect. I have inserted hyperlinks for most cross-references in the text and am responsible for any errors this may have introduced.
The very few typographical errors are corrected and marked with dashed red underlining. In one case, on page 530, I have preferred the wording of the 3rd edition.
