them with regard to their chemical composition ; 
such as the agalmatolite of Klaproth (Bildstein of 
Werner, talc glaphique of Haiiy) employed by 
the Chinese for carving images, vessels, &e.— 
The keffekil or meerschaum, from Natolia, of 
which pipe bowls are made; and a related sub¬ 
stance, called keffekilite, by Dr. Fischer, who dis¬ 
covered it in the Crimea.—Lithomarge, the more 
remarkable varieties of which are, that of a reddish 
yellow colour, from Rochlitz, in porphyry; the 
fine purplish blue variety from Planitz, called 
terra miraculosa Saxonica by old writers.—Ful¬ 
ler’s earth.—Bole; green earth, &c. 
{Case IQ.) In this, and the four following 
glass-cases are deposited the various carbonates of 
lime.—Crystallized carbonate of lime or calca¬ 
reous spar ; specimens illustrative of the cleavage, 
supernumerary joints, colour, &c.; primitive 
rhombohedron (rhomboid); the various secon¬ 
dary rhombohedrons (all of which, together with 
the modifications in the next cases, are deter¬ 
mined after Bournon and Haiiy): among these 
the most common, but not the least striking, is 
the inverse rhombohedron, so called from being 
as it were an inversion of the primitive; the same 
with a considerable admixture of quartz, com¬ 
monly called crystallized sandstone of Fontaine¬ 
bleau, &c. &c.
