Read the excerpt information from The Riddle of the Rosetta Stone, by James Cross Giblin. New translations of the hieroglyphic text were made in France and Germany, and an excellent English one appeared in 1904. A few sections still remain unclear, though. This makes present-day experts hope that an evan more complete copy of the hieroglyphic inscription may not be found, somewhere in Egypt. HURRY!!

The details from the excerpt best support  the central idea that translation of the hieroglyphic text is still not complete.
