40 Reflections on some Mineralogical Systems. 
which minerals receive in common life, and often from 
miners. Every language possesses them, and some of them 
have even passed to others ; as quartz, blende, &e. 
The trivial names may be divided into two: general and 
soporte trivial names. 
. The general trivial names (algemeine triviallen benen- 
ieee) are those commonly used im ahy language and re- 
ceived into another. They are important, inasmuch as they 
are used by philosophers themselves, who have divided 
them into two. 
a. General trivial names (havpt trivialnamen) are those 
most generally known and used. 
b. Accidental general trivial names (nelen trivialnamen) 
are those least known; such as cat- gold or cat-silver (argent 
de chat) [lameliiforme mica, Haiiy], Muscovy elass, tor 
mica, &c. 
2. The particular trivial names comprehend those used 
by certain classes of persons, and in certain countries. They 
are bearesd into three (lesondre trivialnamen). 
Provincial or local names (provenxiellen. und local 
faa): The peasantry in certain provinces use these 
— mispickel, i in Saxony, for arsenical pyrites ; self; 
selferz or gelft, is the Hungarian name of coppery pyrites. 
. Officinal names (officinelle benennungen) are those used 
by apothecaries and a traders in the shops; as blood- 
stone, nephretic, &c. 
c.: Technical names (éechnologische benennungen) are those 
used by artists or workmen. Statuaries call all kinds of 
stone which are easily wrought, marble. 
B. Systematic names (systematische benennungen) are 
those used by philosophers ; ; they should be characterized 
by precision and perspicuity. 
III. Principles and rules for forming these names. 
A. Rule for the formation of general trivial names.— 
Werner gives eight rules for this purpose. The names 
ought to be distinct, definite or clear (wnterscheidend); just, 
with respect to the thing (sachrichtig) ; correct, with re- 
spect to language (spr achrichtig); descriptive (Lexerchnend); 
short (kurz); fixed and applied only to a single mineral 
( festgesetz); unique, (etnzig); and distinct from one an- 
pee (ausgexiechnet). f 
1, A name is distinct when. it belongs only to a single 
species: spar, schiste, and schorl, are not distinct ; but 
feldspar, fluor spar, argillaceous schiste, &e., are. 
2. Tt is just with respect to the thing g, when it does not 
give
