ALABASTER. 
A suBsTANCE, which the workmen denominate 
Alabaster, but not the true Alabaster, which is of a 
different nature, frequently occurs in the Plymouth 
Limestone. It is found in many quarries, in con- 
siderable quantities; particularly in those situated 
between the Ferry-House at Catdown, and the Fly- 
ing Bridge. This substance rises in large blocks, 
and is of various colours, such as a deep red, a 
yellow, mottled with veins and tinges of pink; and 
also of pure white. Of the two latter, I have ob- 
tained, by the fracture of the masses, some very 
large and perfect rhombs, measuring from four to 
Six inches in diameter.
