His "Lettres ecrites d'Egypte et de la Nubie" render his observations and impressions and describe his life and adventures in Egypt, in a most entertaining and instructive style. The many and various inscriptions, copied there by him, are all quoted in his great work on monuments, entitled, "Monuments de l'Egypte et de la Nubie," and in his posthumous work, "Notices descriptives conformes aux manuscrits autographes rediges sur les lieux." Soon after his return to Paris (in March, 1830), by which time his health had commenced to fail, he was elected a Member of the Academy, and in March, 1831, was appointed professor at the "College de France." The solidity and instructiveness of his lectures brought the most celebrated leaders in science to hear him, but there were destined to be but few of the lectures, as he all too soon felt himself too weak to continue them. On March 4, 1832, at his old homestead Figeac, a stroke of apoplexy ended his active life of achievement. His great discovery was at first vigorously attacked. Erring minds declaring the system of the great Frenchman to be wrong, and submitting others of their own, as the Russian Klaproth and the German Seyffarth, disturbed Champollion's peace; still more bitterly, however, was he pursued by the envy and hatred of his political opponents. Even when the laurel already decorated his brow, they saw to it that the thorns were not wanting in the wreath. Especially in England various efforts were made to have, not him, but Thomas Young, recognized as the discoverer of the science of deciphering hieroglyphics. But though Young had succeeded previously to Champollion in deciphering some hieroglyphic names in a mechanical way, yet the genial Englishman mistook, during the whole course of his activity, the real character of hieroglyphic writing. To Champollion, on the other hand, it was left to recognize their nature and construction, so that science must acknowledge him to be the discoverer of the true nature of the system of hieroglyphical writing. Shortly before his death it was vouchsafed him to proclaim to his loyal brother, "_Voici ma carte pour la posterite_," pointing to the manuscript of his "Egyptian Grammar," of which the last chapter was still missing. It contains the germs from which all similar works have sprung, which since have perfected and enlarged that of Champollion; it showed the path in which all subsequent grammarians were to walk. The results of Young's discoveries remain without influence upon the progress of the science, and have found a place long since among old relics. Francois Champollion's work is the seed, which even at the present day brings forth the richest fruits. When he died, at the age of forty-two, he left the world not only his "Egyptian Grammar," but also pioneer works in other branches of his science.
