This Number must be considered as an Appendix to the two former, for, with the exception of
the comparative levels of the water, and of Campbell's Tomb, it has not any relation to the Pyramids
and Monuments of Gizeh. Mr. Perring's researches were, however, a continuation of the inquiries
carried on in 1837, and his plans are made to correspond with those laid down at Gizeh. They
have been lithographed under the able direction of Mr. Arundale, of Berners Street.
The Text, as in the former instances, has been drawn up from Mr. Perrings observations; and
the Inscriptions have been elucidated by Mr. Birch, of the British Museum.
