146 NOMENCLATURE. 



solely upon the species, and consequently, are not required to con- 

 sist of more than one word. The trivial nomenclature in mine- 

 ralogy will, therefore, have the advantage of the systematic, in the 

 conciseness of its names ; which indeed, is the only recommendation 

 it may be said to possess. They are derived, for the most part, 

 from colors, persons, localities, and other accidental circumstances ; 

 of which, the following are good examples: Kyanite, Olivine, 

 Prehnite, Wavellite, Andalusite, Arragonite, &c. 



. 117. NOMENCLATURE IN AN ANALYTICAL SYSTEM. 



The nomenclature in an analytical system must be a 

 trivial one. 



Since, in an analytical system, we must not look for similarity 

 among the species of any one class or order, to name the species in 

 such a manner as to suggest the class and order to which they indi- 

 vidually belong, instead of serving to illustrate or simplify the gen- 

 eral survey of the mineral kingdom, would only produce confusion. 

 A designation, therefore, wholly irrespective of any such relations 

 should be employed. All that we demand of nomenclature, so far 

 as the analytical method is concerned, is the simplest designation 

 of the object possible, from which we may be pointed forward to 

 the descriptions for the remaining information of which we are in 

 search ; we have no interest in being carried back to the artificial 

 ideas by whose means we have accomplished tbis preliminary step. 



It is true, provided the names employed in the analytical method 

 do not lead us back to the orders and classes of that method, it 

 would not be very objectionable what denominations were employed, 

 whether those of the systematic nomenclature, or the chemical 

 names, so far as minerals are possessed of them ; yet, as the ob- 

 ject of this method is only a preliminary step, those which are the 

 shortest and most convenient seem preferable, and these are the 

 trivial names. 



At the same time, care has been taken to give, in a smaller type, 

 the systematic names of Mobs, and some of the important synonyms 

 of other authors, in order to enable the student to refer with con- 

 venience, to the general descriptions in different works upon the 

 science.
