266 HISTORY OF MINERALOGY. 



the steady intuition (anschauung] of objects, were 

 deemed by him, and by the Wernerian school in 

 general, to be the most essential conditions of com- 

 plete knowledge. 



It is not necessary to describe Mohs's system in 

 detail ; it may sufficiency indicate its form to state 

 that the following substances, such as I before gave 

 as examples of other arrangements, calcspar, gypsum, 

 fluor spar, apatite, heavy spar, are by Mohs termed 

 respectively, Rhombohedral Lime Haloide, Gyps 

 Haloide, Octahedral Fluor Haloide, Rhombohedral 

 Fluor Haloide, Prismatic Hal Baryte. These sub- 

 stances are thus referred to the Orders Haloide, 

 and Baryte; to Genera Lime Haloide, Fluor Haloide, 

 Hal Baryte ; and the Species is an additional par- 

 ticularization. 



Mohs not only aimed at framing such a system, 

 but was also ambitious of giving to all minerals 

 names which should accord with the system. This 

 design was too bold to succeed. It is true, that 

 a new nomenclature was much needed in mine- 

 ralogy: it is true, too, that it was reasonable to 

 expect, from an improved classification, an improved 

 nomenclature, such as had been so happily obtained 

 in botany by the reform of Linnaeus. But besides 

 the defects of Mohs's system, he had not prepared 

 his verbal novelties with the temperance and skill 

 of the great botanical reformer. He called upon 

 mineralogists to change the name of almost every 

 mineral with which they were acquainted ; and the
