Secondly, Beddoes has shown an evident connec. tionbetween basalt, trap, and granite ; and a connection of this sort, extorted from Ferber an avowal, that basalt might be produced in the moist way. Thirdly, some singu- lar basaltic pillars were lately discovered in Bohemia, con- taining indurated marl, with the impression of a vegetable resembling cerastium or alpine Mouse-ear. The conse- quence is plain. The difiiculty, then, which now remains, is to. account for the prismatic or columnar form; but this is more easily explained by the Neptunian than by the volcanian theory. For we can produce many in- stances of similar prisms in fossils, produced in the humid way undoubtedly, and none at all undoubtedly formed in‘. the dry way. This form, according to Kirwan, seems to proceed from the sudden bursting of basaltic masses, either from drying, on the absorption of the air. Kirwan was , confirmed in this opinion, from the occurrences of a si- milar kind which took place in a- large block of calp i brought to Dublin, for a foundation-stone of the present- Custom House; this stonevsplit‘ into as regular prisms as ' those of the Causeway. This stone resembles basalt in its composition, but contains a much larger proportion of --an oesu. .. uu -a calcareous earth, and armnch smaller of iron. . ,3" Again,’ inf the province of Volatean, Mr. Dolomieu found‘ micareonsf rnarls. to assume a prismatic form on -1,.,‘.::::.,.,.., K 1 Fl; --‘nun-our . . drying.
