 Beroldingen (FRANZ COLESTIN, Baron VON). [1740-1798] 



Baron von Beroldingen, a Swiss by birth, spent most of his life in 

 Hanover and Rhenish Bavaria, where he held various ecclesiastical 

 appointments. He travelled much for the sake of increasing his know- 

 ledge of mineralogy and geology, and amassed a large number of mineral 

 and other specimens. His collection of minerals, consisting of about 

 14000 specimens, was inherited by his nephew, Count von Beroldingen, 

 and purchased from the latter in 1816. The specimens are small in size 

 and of mediocre quality, but at the time of acquisition they filled gaps in 

 the Museum collection, and in addition had some interest as illustrating 

 the ideas developed by the collector in his published works more espe- 

 cially his "Bemerkungen auf einer Reise durch die Pfalzischen und 

 Zweybriickschen Quecksilber-Bergwerke," published in 1778. A manu- 

 script German catalogue in two volumes is preserved in the Department.

 years according to Berzelius's chemical system.
