OBSERVATIONS. 



1. Fluid Mercury is the* pure metal, as produced by 

 nature. It is entirely volatile before the blowpipe, and 

 easily soluble in nitric acid. 



2. Lake the dodecahedral Mercury, it occurs in the re- 

 positories of peritomous Ruby-blende, in the shape of 

 small globules or drops. Sometimes it is found in narrow 

 fissures of those rocks, which accompany that mineral. 



3. The most important and well known localities of fluid 

 Mercury are Idria in Carniola, and Almaden in Spain. 

 In smaller quantities it is found at Wolfstein and Morsfeld 

 in the Palatinate, also in some places in Carinthia, in Hun- 

 gary, in Peru, and other countries. 



4. The quantity of fluid Mercury found in nature is too 

 small to allow of its being applied to any useful purposes. 

 The metal obtained from the peritomous Ruby-blende, is 

 employed for making thermometers and barometers, also in 

 various chemical and pharmaceutical preparations, in the 

 amalgamation of gold and silver ores, in the production of 

 artificial cinnabar, in the processes of silvering mirrors, of 

 gilding, and for many other purposes.
