JUSTUS VON LIEBIO, born at Darmstadt in 1803, after spending ten 

 months in an apothecary's shop, entered the University of Bonn in 1819, 

 and afterwards graduated in medicine in Erlangen. In 1822 he went to 

 Paris, where he studied chemistry two years. In 1824 he read a paper on 

 the Fulminates before the French Institute, which attracted the attention of 

 Humboldt, by whose influence he was appointed adjunct Professor of Chem- 

 istry in the University of Geissen. He became professor of this institution 

 in 1826, and established here the first laboratory in Germany for teaching 

 practical chemistry. In 1840 he published his " Chemistry in its applica- 

 tions to Agriculture and Physiology," in the form of a report to the British 

 Association. In 1842 he reported to the same body his work on "Animal 

 Chemistry." About the same time appeared his "Familiar Letters on 

 Chemistry," which has since been rewritten and much extended. He is the 

 author also of various other valuable works. He remained at Geissen till 

 1862, when he became professor and president of the laboratory in the 

 University of Munich. In 1854 his friends in Europe contributed and pre- 

 sented to him 1,000, and hi 1860 he became President of the Academy of 

 Sciences in Munich. Professor Liebig is a bold and intrepid investigator, 

 and an ardent writer, who has made a profound impression upon his age. 

 While some of his views have not been accepted in the chemical world, and 

 indeed have been abandoned by himself, others have taken their place as 

 valuable additions to the body of scientific fruth. The charge that some of 

 his doctrines have proved erroneous does not disturb him ; in the true scien- 

 tific spirit he replies, " Show me the man who makes no mistakes, and I will 

 show you a man who has done nothing."
