laboratory work which distinguished the earlier part of his career 
impossible. His work in Munich consisted chiefly in elaborations 
of his previous ideas, and in researches, the results of which are of 
comparatively little general scientific interest, although in some 
cases of considerable practical value. Among these may be men- 
tioned the discovery of the mode of preparing the extract of meat, 
and that of a method of depositing a uniform coherent layer of 
silver of any thickness upon smooth surfaces. 
Liebig was a most voluminous author. His papers were pub- 
lished in many journals, but chiefly in Poggendorff’s “ Annalen,” 
and in the “Annalen der Pharmacie” (now “Justus Liebig’s 
Annalen der Chemie und Pharmacie ”), of which he became one of 
the editors in 1831. Of separately published books, the most 
important are “ Introduction to the Analysis of Organic Bodies,” 
1837 ; “ Chemistry in its Application to Agriculture and Physio- 
logy,” 1840; “Animal Chemistry,” 1842 ; “ Handbook of Organic 
Chemistry” (as second volume of a revised edition of Geiger’s 
“ Pharmacy ”), 1843 ; “ Chemical Letters,” 1844 ; “ On the 
Chemistry of Food,” 1847 ; “ On Some Causes of the Motions of 
the Juices in the Animal Body,” 1848; “Principles of Agricul- 
tural Chemistry, with special Eeference to the late Researches made 
in England,” 1855. Of most of these works many editions were 
published in German and in almost every European language. 
From 1831 till bis death he was one of the editors of the chemical 
journal now known as “Justus Liebig’s Annalen der Cbemie und 
Pharmacie.” Along with Kopp he edited, from 1847 to 1856, the 
“ Jahresbericht fiber die Fortschritte der Chemie ;” and along with 
Poggendorff and Wohler, the “ Handworterbuch der Chemie.” 
His personal character was simple and easily characterised. 
Open, amiable, and generous, vehement in carrying out his convic- 
tions, utterly intolerant of pretence and dishonesty, he was either 
a warm friend or a declared enemy. In controversy he was often 
violent, sometimes ferocious, but he never struck an unfair blow. 
By his death many chemists have lost a friend, and all feel one 
more link attaching them to the last generation broken.
