Transcriber’s Note:
The spelling of place-names has been retained as in the original, except where clearly incorrect (e.g., “Leece, Italy” has been corrected to “Lecce, Italy”) or inconsistent within the book (e.g., “Chili” has been conformed to “Chile”). In the list of [Principal Cities of the World], duplicate place-names with different population figures have been retained as in the original. Pop-up transcriber’s notes are indicated by red dotted underlining, like this.
