 well prepared by these means, he qualified in the 

 University of this place in technology, and afterwards 

 also in physics ; he was appointed extraordinary pro- 

 fessor in 1834, and ordinary professor in 1845, and so 

 distinguished himself by his scientific labours at this 

 time, that nine years after his habilitation, on January 

 27, 1840, he was elected a member of this Academy. 

 From 1832 until 1840 he taught physics in the 

 Artillery and Engineering School ; and from 1850 until 

 1856 chemical technology in the Gewerbe Institut. 

 For a long time he gave the lectures in his own house, 

 using his own instruments, which gradually developed 

 into the most splendid physical collection in existence 

 at that time, and which the State afterwards purchased 

 for the University. His lectures were afterwards given 

 in the University, and he only retained the laboratory 

 in his own house for his own private work and for that 

 of his pupils. 



His life was passed thus in quiet but unremitting 

 activity; travels, sometimes for scientific or technical 

 studies, sometimes also in the service of the State, and
