These volumes are reduced from the original Folio edition and bear a publication date of January 1st 1812. The size of the binding is 36cm high x 27cm wide.
All of the plates are present apart from one:
Volume one contains all the plates 1-24 in parts 1, 2 and 3
Volume two contains all 24 plates in part 4, is missing plate 14 in part 5 and retains all 24 plates and eight plans in part 6
The missing plate in part 5 does not appear to have been torn out or lost but instead simply does not appear to have ever been bound in.
There is some wear to the bindings with rubbing to spines and covers. Slightly dog-eared. Internally the text is slightly foxed and stained in places.
