The author was one of the foremost scientists of Germany during the XVII. Century, and although his works do not con- 

 tain many new discoveries, they are valuable for giving an encyclopedic view of the sciences treated as they were known 

 in his time. For the historian of physical science they are invaluable. 



He is known as the inventor of the magic lantern (originally suggested by Porta), and of Ihe seoliau harp (in the last- 

 named woik), unless that honour belongs to St. Dunstan. He was also the first to mention physiological colours, and to 

 issue charts of the oceanic currents.
