It is not certain which edition of this work was in Jefferson’s library. The book is marked missing in the working copy of the 1815 Catalogue, and the entry is omitted from subsequent editions. It is on the manuscript list of missing books made after 1815. Dr. Kimball, page 94, credits Jefferson with the edition of 1724, and suggests that he may have acquired the book with his purchases from the library of William Byrd of Westover. The book is entered by Jefferson without price in his undated manuscript catalogue.
The fact that this book was entered by Jefferson in his undated manuscript catalogue presupposes that he acquired it during his residence in Europe rather than at the sale of the library of William Byrd of Westover.
William Halfpenny, alias Michael Hoare, fl. 1752, English architect and carpenter. He practised architecture in London in the first half of the eighteenth century and was the author of a number of books on the subject.
