Petrie, William M. Flinders: Researches on the great pyramid, or fresh connections, being a preliminary notice of some facts and a fuller statement (London, 1874)

The following researches on this Monument confirm those distinctive principles of
its design and construction, first announced by the sagacity of John Taylor and Pro-
fessor Piazzi Smyth, as they were set forth in Professor Smyth's first publication on
this subject, α Our Inheritance in the Great Pyramid/' first edition, published just ten
years ago.

The many fresh facts here noticed, while shewing much further and interesting
development of those same principles, add irrefragable proof of their validity as against
superficial theories, old and new.
