TRANSCRIBER’S NOTE

Original spelling and grammar have been generally retained, with some exceptions noted below. Original printed page numbers are shown in curly brackets like this: {52}. Footnotes have been relabeled 1–65, and moved from within paragraphs to nearby locations between paragraphs. Many of the page headers in the original book were significant as text headings, and have been retained, formatted as all capital letters in angle brackets, e.g. “〈DIFFICULTIES NOT ANSWERED.〉”. These have been inserted into the running text at the appropriate places between paragraphs. Oc­ca­sion­al­ly such location might be somewhere in the page preceding the original page header. The transcriber produced the cover image and hereby assigns it to the public domain. Large curly brackets, intended to graphically indicate the combination of information on two or more lines of text, were eliminated. The related text was restructured appropriately to retain the original meaning. Instances include page [61], page [276], and page [364].
