tlie process of fusion ; in which case their imbedded minerals 

 must be referred, as those of granite are, to an igneous origin. 



Saline Minerals. 



Carbonat of lime. Carbonat of barytes. 



Fluatoflime. Sulphat of barytes. 



Gypsum. Carbonat of strontian. 



Brownspar. Sulphat of strontian. 



Arragonite. Boracite. 

 Wavellite. 



With respect to some of these, it will be perceived that 



the proofs are complete, as they are found in the^ following 



division : 



Minerals of the Amygdaloids. 



Quartz ; including amethyst. Mesotype. 



Chalcedony, in all its varieties. Nadelstein. 



Opal. Leucite. 



Sulphat of barytes. Sulphat of strontian. 



Fluor spar. 



Olivin. Prehnite. 



Epidote. Laumonite. 



Mica. Ichthy ophthalmite. 



Chlorite. Harmotome. 



.Steatite. Analcime. 



Lithoniarge. Stilbite. 



Chlorophjeite. Chabasite. 



Conilite. Arragonite. 



Brown spar. 



To which may be added, as found sometimes in aqueous 



quartz, 



Disthene. Tremolite. 



Epidote. Tourmalin. 



Actinolite. 

 And as found in calcareous spar, 



Emerald. 

 I have here limited the list of aqueous minerals strictly to 

 those which are supported by the proofs above-mentioned j 

 but, if those also had been enumerated which are found asso- 

 ciated together in cavities of veins, where one or more of the 

 number consists of minerals decidedly aqueous, it might have 

 been considerably extended. The mineralogical reader who is 

 thus furnished with the principles on which this catalogue has
