 the Electorate of Salzburg. He then retired from public life, and devoted 

 his leisure to scientific pursuits at Munich, and later at Augsburg. His

 Tyrol, were thus added to the collection.

Monticelli (TEODORO). [1759-1846] 



Monticelli, a benedictine, was for two years [1792-1794] professor of 

 ethics at the University of Naples. The following years, till 1800, were 

 spent in prison, as a result of his participation in the political disturbances 

 of the time. He was appointed professor of chemistry at the University 

 of Naples in 1808. His large collection (upwards of 2000 specimens) of 

 Vesuvian products, both minerals and lavas, etc., was purchased in 1823. 

 The results of a study of these products are given in Monticelli and 

 Covelli's " Prodromo della Mineralogia Vesuviana," 1825. A manuscript 

 list of the specimens, in the handwriting of Covelli, is preserved in 

 the Department. Many of the best specimens of crystallised Vesuvian 

 minerals now in the Museum came as part of the Monticelli collection.
