Dr. Bright upon the hills of Badacson , Sxigliget, idc. 5 
in their natural situation, forming part of the solid rock. Proceeding 
a little higher, the rock was a species of greenstone, or perhaps lava, 
but suffering considerably from the action of the weather, and then 
thickly beset with little hollows, slightly indented and about the size 
of a pea ; this was of a light grey colour, and in its structure quite 
amorphous. Still higher, the same rock became more hard, and 
shewed a tendency to assume a vertical columnar division. 
Such was the formation of this hill, of which however I possess 
no specimens. 
The lower part of the hill Badacson, was completely covered with 
vegetables, but on ascending about half way we found the whole 
strewed with fragments fallen from above, amongst which were 
masses of very vesicular scorise. 
The path leads through columnar rocks, called the Iron Gateway, 
formed of a very compact, hard, dark coloured stone, of a crystal- 
lized texture, rather resembling clinkstone. In other parts, towards 
the summit, the rock is of a greyer colour, containing numerous 
small particles of olivine and a few vesicular cavities. It here as- 
sumes the general, though not regular columnar form, and splits 
again horizontally into layers of six or seven inches in thickness. 
The highest part of this insulated hill is covered with wood, and 
many of the oaks have attained a large size where their growth has 
been favoured by an irregular natural excavation, formed by the 
disposition of the surface. Descending on the west side of the hill 
where the rock was more denuded than at the part we had first ap- 
proached, I was not a little surprised to meet with a sandstone con- 
glomerate, bearing a very exact resemblance to the only rocky mass 
which occurs on the ascent of Hekla, and is found forming complete 
mountain ranges in Iceland, as will be found ably described by Sir 
George Mackenzie.
