Transcriber's Notes

The text presented here is essentially that in the original printed volume. The list of corrections (

CORRIGENDA

) which accompanied the original has been applied. One additional typo (see below) has also been made. There may have been some minor corrections (missing period, commas, etc. added) which are not detailed here. In the original publication, several figures and plates were placed in the middle of paragrahs. Here most were moved between paragraphs. The List of Illustrations and any other page references still indicate the page number of the original location.
