our possession, which are from standard localities in Europe. 
The crystals are eminently axotomous, and this cleavage is so 
easily obtained, that it is with great difficulty the crystals can be 
preserved entire. The cleavages parallel to the sides of the 
right square prism are easily obtained, but the natural joints are 
not so open as in the direction of the terminal plane. It agrees 
likewise in chemical characters with the apophyllite from the 
Bannat; hence there can be no doubt of its identity with that 
species. 
In visiting this interesting locality the second time in 1828, we 
were unable to gain access to this remarkable cavity, as the 
frightful cliff, that before hung over it, had fallen during the winter, 
and buried it among the ruins. But we met with other localities 
scarcely less interesting in this vicinity, in the numerous cavities 
and arches that have been hollowed out by the surges from the 
softer amygdaloid that is traversed by veins of a yielding nature ; 
such as carbonate of lime and sandstone, the last rising probably 
from the immediate substrata of' this rock, on which the trap 
reposes. ‘These veins, at the inner extremities of the caverns, 
are frequently hollow and lined with stilbite, heulandite, and 
more rarely with apophyllite, in greenish white square prisms, an 
inch in length. Masses of laumonite, with surfaces more than a 
foot square, were obtained from them, and were found complete- 
ly studded over with projecting crystals of great richness. One 
of these, we succeeded in preserving entire, and its crystals now 
possess all their native beauty and transparency. They show no 
tendency to effloresce when immersed in spirits of wine; a fluid 
which has great advantage over water in the winter season in 
not endangering the vessels in which the specimensare preserved.
