Note 13 — LETTER VI.
Reading edition
“I measured” (says my brother) “the height of a zóba’ah, with a sextant, at Thebes, under circumstances which insured a very near approximation to perfect accuracy (observing its altitude from an elevated spot, at the precise moment when it passed through, and violently agitated, a distant group of palm-trees), and found it to be seven hundred and fifty feet. I think that several zóba’ahs I have seen were of greater height. Others which I measured at the same place were between five and seven hundred feet in height.”—Modern Egyptians, 3d Edition, Part I. chap. x.
