chemical composition j such as the agalmatoUte 
of Klaproth (bildstein of Werner, talc glaphique 
of Haiiy), employed by the Chinese for carving 
images, vessels, &c.—The keffekll or meerschaum, 
from Natolia, of which pipe bowls are made; and 
a related substance, called keffekilite by Dr. Fischer* 
who discovered it in the Crimea.— Litlmnarge, 
the more remarkable varieties of which are, that 
of a reddish yellow colour, from Rochlitz, in por¬ 
phyry; the fine purplish blue variety from Planitz, 
called terra miracidosa Saaconica by old writers.— 
Fuller's earth. — Bole; green earth, &c. 
(Cases 19 and'. 20.) In these and the three follow¬ 
ing table-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 rhom- 
bohedron ; various secondary rhombohedrons: 
amongst 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, 
commonly called crystallized sandstone of Fon ¬ 
tainebleau. Prismatic and pyramidal modifications 
of the same, among the formei of which are the 
beautiful varieties from theHartz, Salzburg, &c.*

nate of lime see the British Collection, especially Derbyshire and
