The Essay of Mons. Greppo is composed of two parts, the first of which is an explanation of the hieroglyphic system of Champollion; and the second, the application of the hieroglyphic system to the elucidation of the sacred writings. The relations of the Hebrews with the Egyptians were such, that the history of the latter cannot be otherwise than most intimately connected with the religion of the Bible. In fact, there was no country in the world, foreign to Judea, whose name is so conspicuous in the Bible, as that of Egypt; beginning at the time of Abraham, and going down to the very Apostolic age; and it hence follows, that he who would study in detail, the historic annals of the Hebrews, ought to be as fully acquainted with those of ancient Egypt, as the largest means will allow. In carrying out his intention, M. Greppo has gone deeply into philological, historical, chronological, and geographical considerations. By making the "précis" of Champollion the basis of his argument, and bringing in to his assistance the labours of the elder Champollion, called by way of distinction Champollion Figeac, from the place of his residence; he has investigated the history of the Pharaohs, as connected with the accounts given in the books of Genesis and Exodus, and the later historical writings. In the fourth chapter of the second part, there is an interesting discussion relative to the difficulty of reconciling the position taken in Exodus, as to the perishing of Pharaoh, with the conclusions drawn from the investigations of Champollion. The last Pharaoh of the Exodus, is ascertained to be the King _Amenophis Ramses_. According to Manetho, he reigned twenty years; viz. from 1493 B. C., to 1473 B. C., so calculated also by Champollion Figeac. But the departure of the children of Israel took place about the year 1491 B. C., consequently in the second or third year of this Prince. If this Prince perished in the Red Sea, how can this be reconciled with the fact, that Manetho states him to have reigned twenty years, and this is confirmed by the calculations of the elder Champollion. M. Greppo goes into an interesting discussion, to prove that the text of the Book of Exodus does not state that Pharaoh perished in the Red Sea. His examination of the sacred text will be interesting to many of our readers:
