Dr. Bright upon the hills of Badacson, Szigliget , EsV. 7 
whole had been very nearly, if not quite in a state of fusion, at the 
time when it assumed this appearance; and this view of the subject 
is rather confirmed by the very intimate union which exists between 
all the parts of the conglomerate. It is however possible that the 
scoriated appearance does actually arise from scoriae included in the 
mass, so that on the application of intense heat a partial fusion takes 
place, by which the matrix and the included substances have been 
closely united together. 
Upon the summit of the hill and forming the foundation of the 
castle, the conglomerate, still containing the same substances, is 
found in a form somewhat different, disposed in beds of various 
thickness with a very distinct separation between them, both sur- 
faces of the beds being composed of projecting and slightly adhering 
angular particles of which the greater part is composed. These beds 
are perhaps at an angle of about 45° to the horizon. They are 
several yards distant from the vein, part of the general conglomerate 
filling up the intervening space. 
The important conclusion to which these facts incline my mind 
is, that a vein which resembles in its characters a true basaltic green- 
stone, has owed its origin to the action of fire. 
No one can look upon the hills of which I have been speaking, 
and observe how insulated they are from all mountain chains, mark 
their form, their abrupt sides and their flattened tops, without being 
convinced that they are but remnants left by some convulsion, tear- 
ing away parts which either connected them together, or made of 
each a more perfect whole. We must therefore put their form en- 
tirely out of consideration, and look upon them simply in the light 
of fragments, retaining their natural situation. 
As such then we find in the first a hard columnar mass, in close 
connexion with a great mass of scoriated lava, over which it lies.
