A few general remarks, that I had taken the liberty of sending out to Mr. William Bankes, for his assistance in his Egyptian researches, had been found of some utility in directing his attention to points of the most material importance for the promotion of the investigation: and even before the actual publication of the Supplement of the Encyclopaedia, I had received from Egypt a very agreeable confirmation of my opinions, in a letter addressed by Mr. Salt to Mr. William Hamilton, of which I shall here insert an extract. “_Cairo, 1st May, 1819._ “At Dakki in Nubia there is an inscription of the Ptolemies, over the principal entrance, that occupies a place evidently connected with the architecture; and on each side of this is a tablet of hieroglyphics, nearly similar one to the other. Now it struck me on the spot, that these, being nearly of the same length as the Greek tablet, might possibly contain a translation. I therefore referred to a letter in Mr. Bankes’s possession, containing some fifty explanations of hieroglyphics from Dr. Young, and was certainly gratified to find that in the oval [ring], conspicuous on each side, was the name of the “immortal Ptolemy”: and immediately afterwards the name of Hermes on one side, and of Isis on the other, to whom, by numerous Greek inscriptions, it is certain that the temple was dedicated. In following up this idea, I found, in other parts of the temple, the name of “Ptolemy“ without the “immortal,” over offering figures; and also those hieroglyphics which Dr. Young supposes to represent the names of Osiris, Isis, and Horus, as well as Hermes, over their respective figures, invariably, I may say, throughout the numerous representations on the walls....
