The basalt, or trap, forms in the Vicentin bed like veins, 
and veins in the recent talcose schists, and in zechstein and 
red marl. These last are altered in a most singular way 
at their contnet ‘The same rocks cut all the mepondary

coarse tertiary limestone. But the most singular fact is

nothing but this tertiary igneous rock, and are like beds, 
or in columns in the juratié limestone. It is astonishing 
te the errors on this point should so long have been over-

In Switzerland there are two molasses, one is like the 
red marl, like the Carpathic, what Beudant calls his Gres 
houiller ; and the other is tertiary, and is divided into in- 
ferior molasse with lignite, and superior with marine 
shells.
