Notes:
Plates 11-21 are not paginated but counted in the page sequence. Page [193] is Plate 21. Plates 11 and 16 are (in the pdf) duplicated at higher density to reveal details in the faint drawings on each plate. The images of the drawings in the high-density scans are actually improved over those on the original plates.
