2. It occurs in large translucent crystals in the cavities of amygda- 

 loid at the Giant's Causeway in Ireland ; forming groups of sheaf-shape 

 aggregations at Capo di Bove near Rome ; at Aci Reale, on the eastern 

 coast of Sicily, Marburg in Hessia, Lowenstein in Silesia and among the 

 Lavas of Vesuvius. The specimens from Aci Reale present elongated 

 crystals, which adhere closely together, and radiate from a centre in 

 globular concretions. It has also been found with Gmelinite in the isl- 

 and of Magee, Antrim county, in minute flesh-red colored crystals, 

 coating cavities of amygdaloid.
