Griotte, the name of a variety of cherry, is applied to marbles 
having markings suggesting a mass of ripe red cherries. 
Jaspe refers to specimens of the color of Jasper. 
Breche, or breccia, is applied to those marbles which appear 
to be composed of angular fragments cemented together. 
Brocatelle is said to refer to a kind of cloth. Marbles having 
the appearance of any of the brocatelles shown here may with 
propriety be called brocatelle. 
Campan marbles are those showing a peculiar green net-work 
of veins. 
A Coquille marble is merely a shell marble. 
Other names are either simply descriptive, refer to localities 
or have no especial significance. 
Case 3.— Marbles, Italy. Among these are some used by the 
ancient Romans. 
Case 4.— Marbles, Africa. Serpentines. Next to marble 
the green or red serpentines are perhaps the most generally used 
of ornamental stones. Especially noteworthy are the curiously 
mottled red and dark green serpentines from Lizard Point, Corn- 
wall, and the dark colored variety from Saxony which is turned 
on a lathe to form various ornamental objects. 
Case 5,— Verde antique, ophite. The green serpentines

ophite from New York is a granular mixture of calcite and serpen,

stalagmite marble. The clear translucent specimens represent 
the travertine as originally deposited. The opaque red-brown 
effects are produced where air has had long access to the material 
in the ground and has caused oxidation of the iron contained in 
the specimens. 
Case 7.— Marbles, United States. The most widely used 
United States marbles, all of which are illustrated here, are the 
Vermont, Georgia and Tennessee marbles. The Vermont mar- 
bles are fine textured and range in color from pure white through
