On the Geology of Norway and Lapland, extracted from 
L. Von Buch’s Travels * in that Country. By Profesor 
Jameson of Edinburgh. 
This philosopher, a native of Prussia, although a pupil 
of Werner, has submitted the theories of his master to 
his own reason and observation, and presented the public 
with a more impartial, complete and interesting view of the 
geology and mineralogy of the countries in which he has 
sojonrned, than any other traveller of the Wernerian school. 
Professor Jameson gives the following summary of his 
geological researches : 
‘© 1, Norway and Lapland are principally composed of 
primitive and transition rocks; floetz rocks occur very 
rarely, and alluvial rocks are uncommon. 
«<9, Granite, contrary to the general belief of mineralo- 
gists, is a rare rock in Norway and Lapland, it even occurs 
but seldom in Sweden, and it is to be considered as one of- 
the least frequent of the primitive rocks in Scandinavia. 
“<< 3, The granite frequently alternates with gneiss. 
«4, A newer granite sometimes occurs resting on mica- 
slate, as at Forvig ; or connected with clay-slate and dial- 
Jage rock, as in the island of Mageroe. 
“© 5. Besides the gneiss, which is associated with the 
oldest granite, there is another of newer formation, which 
rests upon miica-slate. 
<¢ §.'Gneiss appears to be by far the most frequent and 
abundant rock in Scandinavia, all the other primitive rocks 
appearing in some degree subordinate to it. 
_ 7. Inthe island of Mageroe and in other quarters of 
Norway there appears a species of simple aggregated moun- 
taia-rock, composed of compact felspar and diallage. This 
rock is the Gabbro of the Italians, and appears in Norway 
to be connected with clay-slate. Y 
«« g, All the magnetic iron-stone of Scandinavia occurs 
in beds in gneiss, and not in veins, as has often been main- 
tained by mineralogists. 
** 9, The class of transition rocks in Norway contains 
besides graywacke, alum-slate, clay-slate, limestone, and 
other rocks well known to mineralogists as members of 
that class, the following rocks: (a) granite, which some-
