In 1865 he was appointed superintendent of a bureau at Wash- ington for the preservation of the records of the confederate government, and in 1870 he was chosen, by the united approval of the United States and Mexico, as final arbitrator in important cases pending between the two countries.

LIEBIG, Justus yon, baron, a German chemist, born in Darmstadt, May 12, 1803, died in Munich, April 18, 1873. While a youth he was taught in the gymnasium of his native town ; and, after spending ten months in an apothecary's establishment, he entered in 1819 the university of Bonn. Afterward at Erlan- gen he obtained the degree of M. D. By the assistance of the grand duke of Hesse-Darm- stadt he was enabled in 1822 to visit Paris, where he devoted two years to the study of chemistry. In 1824 he read a paper before the French institute on the chemical composi- tion of fulminates, which attracted the atten- tion of Humboldt, and by his influence Liebig was appointed adjunct professor of chemistry at Giessen. In 1826 he was made professor in the university, and soon established a labora- tory for teaching practical chemistry, the first of the kind in Germany. It became a resort for students from different parts of the world, and especially from England, among whom are found the names of Lyon Playfair, Gregory, and Johnston. Hofmann, Will, and Fresenius were his assistants. In 1832 Liebig with Prof. Geiger of Heidelberg established the Annalen der Pharmacie, to which he continued to be a contributor till near the time of his death, and scarcely a volume of which up to 1802 does not contain some important paper by him. In 1838 he visited England, and at the meeting of the British association for the advancement of science read a paper on lithic acid, in which
