Barris specimens of Stilbite are found chiefly in Scot- 
land and Ireland. It may generally be known by the la- 
minated texture of its crystals, which are often so small as 
scarcely to be distinguished without the assistance of a 
magnifying glass. The specimens figured came from 
Strontian. The crystals of the upper one are very small 
and confused, excepting a few that stand higher than the 
rest, and are scattered about the specimen. The other 
side of the specimen consists of Carbonate of Lime in six- 
sided prisms, with flat ends, being what is commonly 
called truncated—see the right hand upper outline. 
These crystals of Carbonate of Lime must not be con- 
founded with those of the Stilbite. It is somewhat re- 
markable that, of specimens which come from Strontian, 
Carbonate of Lime frequently occupies one side and Stilbite 
the other.
