Transcriber’s Notes Punctuation and spelling were made consistent when a predominant preference was found in this book; otherwise they were not changed. Simple typographical errors were corrected; occasional unbalanced quotation marks retained. Ambiguous hyphens at the ends of lines were retained; occurrences of inconsistent hyphenation have not been changed. In Chapter VI, the word “The”, followed by the italicized name of an organ, sometimes was italicized and sometimes was not. This possible inconsistency has not been changed here. Footnotes, originally at the bottoms of pages, have been collected and placed just before the Index. Index not checked for proper alphabetization or correct page references. Page 3: “e sudore britanico” was printed with a macron above the “n” (n̄). Fig. 1: “Sir William Beechey” was printed as “Beeching”, but the name appears correctly in Footnote 5, originally on page 4.
