Transcriber Note
Some of the quoted passages have unusual spelling for some words. These were left as is; but other minor typos have been corrected.
The [Table of Contents] and [page 69] list name "Skapta-Jokul" and "Skaptar Jokul" respectively. A web search shows that the more common spelling was "Skapta Jokul" and both were changed to that. Some page references in the Table of Contents were corrected. A reference to "Plate XVI, fig. 4" on [page 246] has been corrected to "Plate XV, fig. 4". Illustrations were moved so as to prevent splitting paragraphs. All materials were obtained from The Internet Archive and any files produced are placed in the Public Domain.
