 pears disseminated in some lime-stones, as 

 in Swisserland and Sicily. The fine crys- 

 tals from Conilla, in Spain, are intermixed 

 with calcareous spar, on a rock of bluish 

 indurated clay ; and they contribute to the 

 elegant study of the Gemmologist. The 

 Metallogist has also frequent occasions to 

 describe the sulphurets, or combinations 

 with sulphur, formed by many metals. If 

 any objection should arise to this arrange- 

 ment, the Salts and Combustibles may be 

 thrown into appendixes ; for the theme is 

 too confined to form a distinct province in 

 the mineral kingdom. 



From these considerations the rocks of 

 common salt, with the bituminous, sul- 

 phuric, and metallic, as those of iron, are 

 ranked among the Anomalous ; while those 

 intermixed with pyrites are so trivial, that 

 it is scarcely necessary to distinguish them, 

 even from the common Modes of the Subr 

 stantial Domains.
