and the coarsely striated one, may make several degrees to 
the more compact or amorphous sort one way, or to the 
crumbly or dusty the other way.—This latter is said to be 
washed from the Gypsum in the rocks, and is called Gyp- 
sum earth, but is a mere variety, and seldom occurs: in- 
deed it would seem rather remarkable if it should remain 
long in a dusty state, especially as at the Baths of St. Philip, 
in Tuscany, the stream deposits the Gypsum as it passes, 
so as to make casts. This is now so contrived as to de- 
posit it with the greatest nicety into moulds of the neatest 
workmanship, when generally the basso-relievo medals or 
figures taken out, are as hard as those made from baked or 
manufactured Plaister of Paris, as it is usually called. 
Gypsum has been in use for ages as a manure, and is 
now become very fashionable, large manufactories being 
established for grinding, and patents taken out for the pre- 
paration.
