Since 1850 he had been a member of the Berlin Academy of Sciences, and since 1858 a corresponding member of the _Institut de France_. He had besides been elected member of almost half a hundred learned societies. After the death of Trendelenburg, when the office of secretary of the Berlin Academy of Sciences was vacant, he was asked if he would be inclined to assume it, and only after his decided refusal, and at his suggestion, was E. Curtius chosen. In 1872 he received the most honorable of all German decorations, the order _pour le mérite_ for science and the arts. He had already, in 1869, been appointed a knight of the Bavarian order of Maximilian, which was closely related to the foregoing. In 1883 he was appointed Government Upper Privy Councellor. The unusual and numerous ovations which he received during the same year upon the occasion of his Doctor’s Jubilee of fifty years, were such as have fallen to the lot of but few scholars. His later works on Egyptian art and the oldest texts of the “Book of the Dead” have been already mentioned. Connected with these were a series of valuable monographs[88] published in the Transactions and Monthly Reports of the Berlin Academy of Sciences, and in the “Zeitschrift für ägyptische Sprache und Alterthumskunde.” In his seventieth year, after an apoplectic attack which slightly crippled his arm, he presented his long-expected Nubian Grammar[89] to science. This work, which marked an epoch, comprised the results of many years of study. Throughout his whole life as a master workman he had been engaged in arranging the philological material which he had acquired while in Ethiopia and on the Blue Nile. He had illuminated this mass of knowledge by profound study, and so greatly added to it that, as far as the works then in existence permitted, he had gained a mastery over all branches of language upon the African continent.
