regarding these red lines?

J Wall had that article scanned and linked - but the scans have gone now that photos are no longer linked to the historical messages.

I sort of need a definite link to reference with page numbers - either article would do,

Firth, C. M., J. E. Quibell and Lauer, J.P.
1935 Excavations at Saqqara : The Step Pyramid. Cairo.

is the book from which the quote is taken, but I don't have access to it and can't check it and get a page number....

Thanks for help so far Kanga.
