Young's specific discoveries were these: (1) that many of the pictures of the hieroglyphics stand for the names of the objects actually delineated; (2) that other pictures are sometimes only symbolic; (3) that plural numbers are represented by repetition; (4) that numerals are represented by dashes; (5) that hieroglyphics may read either from the right or from the left, but always from the direction in which the animals and human figures face; (6) that proper names are surrounded by a graven oval ring, making what he called a cartouche; (7) that the cartouches of the preserved portion of the Rosetta Stone stand for the name of Ptolemy alone; (8) that the presence of a female figure after such cartouches, in other inscriptions, always denotes the female sex; (9) that within the cartouches the hieroglyphic symbols have a positively phonetic value, either alphabetic or syllabic; and (10) that several different characters may have the same phonetic value. Just what these phonetic values are, Doctor Young pointed out in the case of fourteen characters, representing nine sounds, six of which are accepted to-day as correctly representing the letters to which he ascribed them, and the three others as being correct regarding their essential or consonantal element. It is clear, therefore, that he was on the right track thus far, and on the very verge of complete discovery. But, unfortunately, he failed to take the next step, which would have been to realise that the same phonetic values given the alphabetic characters within the cartouches were often ascribed to them also when used in the general text of an inscription; in other words, that the use of an alphabet was not confined to proper names. This was the great secret which Young missed, but which his French successor, Jean Francois Champollion, working on the foundation that Young had laid, was enabled to ferret out. [Illustration: 296.jpg JEAN FRANCOIS CHAMPOLLION] Young's initial studies of the Rosetta Stone were made in 1814; his later publications bore date of 1819. Champollion's first announcement of results came in 1822; his second and more important one in 1824. By this time, through study of the cartouches of other inscriptions, he had made out almost the complete alphabet, and the "Riddle of the Sphinx" was practically solved. He proved that the Egyptians had developed a relatively complete alphabet (mostly neglecting the vowels, as early Semitic alphabets did also) centuries before the Phoenicians were heard of in history.
