or words of a spoken language. Now in the hieroglyphic writing of ancient Egypt, along with those pure phonetics or letters of an alphabet, are found numerous survivals of the older systems from which they sprung, and Champollion, who first attempted the task of forming a hieroglyphic dictionary and grammar, had to contend with all the difficulties of ideograms, polyphones, determinatives, and other obstacles. Those who wish to pursue this interesting subject further will do well to read Dr. Isaac Taylor's book on the Alphabet, and Sayce on the Science of Writing; but for my present purpose it is sufficient to establish the scientific certainty of the process by which hieroglyphic texts are read. With this key a vast mass of constantly accumulating evidence has been brought to light, illustrating not only the chronology and history of ancient Egypt, but also its social and political condition, its literature and religion, science and art. The first question naturally was how far the monuments confirmed or disproved the lists of Manetho. Manetho was a learned priest of a celebrated temple, who must have had access to all the temple and royal records and other literature of Egypt, and who must have been also conversant with foreign literature, to have been selected as the best man to write a complete history of his native country for the royal library in Greek. Manetho's lists of the reigns of dynasties and kings when summed up show a date of 5867 B.C. for the foundation of the united Egyptian Empire by Menes, a date which is of course absolutely inconsistent with those given by Genesis, not only for the Deluge, but for the original Creation. It is evident that the monuments alone could confirm or contradict these lists, and give a solid basis for Egyptian chronology and history. This has now been done to such an extent that it may fairly be said that Manetho has been confirmed, and it is fully established, as a fact acquired by science, that nearly all his kings and dynasties are proved by monuments to have existed, and that successively and not simultaneously, so that the margin of uncertainty as to the date of Menes is reduced to one of a few hundred years on one side or other of 5000 B.C.
