CAQLX carbonata coralliformis. 
Coralliform Limestone. - 
Div. 2. Imitative. 
Denrzysutre, Cumberland, Westmoreland, and some 
parts of Scotland and Ireland, have large remains of these 
coralloid Limestones, often called Marbles; which, when 
compact, being cut and polished, serve for tables, slabs, 
and other ornamental masonry. They vary much in co- 
jour, are of different stronger or paler reds, and sometimes 
the Madrepore is light with a dark or black ground; but I 
have some exactly the reverse, given me by Lady Wilson, 
from the north of England. Some specimens are of a 
larger variety, or a species nearly allied to this. Perhaps 
there are numerous species, as we have no reason to sup- 
pose there were not as many Corals formerly as now, and 
some are so nearly alike that we can scarcely determine 
the different species. The redder ones which I have by 
favour of Gilbert Laing, Esq., are found at Limeworth 
near Arundale in Dumfriesshire, and are often very beauti- 
ful; they are commonly called Bengang and Aboyne Marble. 
This is a larger species than that before described, and is 
lodged in red Limestone, which might be called Eisen-calk 
with as much propriety, by the Germans, as Quartz or 
Flint, coloured by red Oxide of Iron, is called Eisen-kiesel, 
and Clay under similar circumstances Eisen-thon. If the 
nomenclature is good, there cught to be such a concordance, 
when nature agrees with it.
