It is impossible to determine when this natrolite occurrence was first discovered, but it has been known at any race locally for many years, and specimens of the mineral may frequently be seen in collections, where, however, they are usually labelled as from the Giant's Causeway. This error in localization is largely accounted tbr by the fact that the guides at the Giant's Causeway regularly offer specimens of the mineral for sale to visitors, together with other so-called Giant's Causeway minerals, fossils, and flint implements. |
