Plates are numbered continuously through the volume; Figures are numbered from 1 within each article.

Some illustrations have been repositioned to avoid breaking up the text. Page numbers in the table refer to the original printed volume. Plates were unpaginated; numbers such as “85” or “129” mean “facing page 84“, “facing page 128”. When a Figure took up a full (numbered) page, its page number is shown in italics. They may be slightly out of sequence with nearby page numbers.
