Plate III. North East Angle of the Great Pyramid James, Sir Henry

One of four photozincographs printed in Notes on the Great Pyramid of Egypt by the Ordnance Survey Dept. Sgt. McDonald has been suggested as the photographer, probably based on the fact that he was part of the survey in Jerusalem that helped on this project.

There are three photo-zincographic books generally found with photographic images: the second edition of "On Photo-Zincography," 1863; Photographic Views of Netley Abbey (1864) and this book. The process was little used because it was only done by a government printing concern and therefore limited to products of the Survey. Usually photolithography in England is discussed only in terms of John Pouncy and the Survey Office. however, as can be seen by other titles in the David A. Hanson Collection Of The History Of Photomechanical Reproduction The Clark, more was done with this process than has normally been assumed."–Hanson Collection catalog, p. 35
