face of a hill. At this point, Mr. Ansted believes, that the lower 
beds of the coal measures are not only brought up, but are bent over 
the upper, because, though the dip of the strata is to the S. E. or 
in the direction of the section, yet, on the summit of the hill above 
mentioned, is exposed an excellent natural surface of chert; and in 
a quarry near the top the inclination of the beds is about 25° S. E. 
or in the regular dip of the coal measures; and in a narrow valley 
at the bottom of a somewhat rapid descent, the lowest division of 
the greywacke is exposed dipping S. or actually overlying the coal 
measures. This inversion of superposition, Mr. Ansted explains by 
assuming, that the granite comes near the surface, and that by its 
agency the graywacke has been thrown into a trough, and its lowest 
beds so brought up as to be made to rest against inverted beds of 
the coal measures. Proceeding in the line of section, the author 
found in graywacke shale, portions of a Trinucleus, Trilobites or- 
natus. (Trans. Prague National Mus. Soc. 1833.*) 
The graywacke shell extends with contorted strata to an anti- 
clinal hill of limestone, beyond which occur broken and rotten 
shales, then limestone, next shales again, and lastly the picturesque 
limestone hill of Karlstein. Further south is a valley of graywacke 
bounded by an altered rock, which is succeeded by granite. The 
Karlstein limestone is stated to be identical with that at Ginetz, 
(see section 3) and the two other localities in the present line of 
section. It is ofa pale blue colour, very hard, contains several species 
of Orthocera and Trilobites, and is of great ceconomical importance. 
The recurrence of the same limestone at different points, Mr. Ansted 
explains, by supposing, that the granite in these cases, is also near 
the surface, and that a displacement of it, bent the yielding shales, 
but snapt asunder a brittle band of limestone once continuous, the 
portions of which not removed by subsequent operations, are ex- 
hibited at the points mentioned in the line of section ; and that the 
consequences of these operations have been, a disturbance in the re- 
gular succession, and an exhibition of the beds in the following order : 
granite, altered rocks, newest graywacke with limestone, oldest gray- 
wacke, coal measures. 
In conclusion, Mr. Ansted offers the following observations as the 
resuits of his examination of this portion of Bohemia. The gray- 
wacke series is imperfectly developed, presenting at only one spot a 
passage upwards into the carboniferous series, and no passage down- 
wards into the graywacke, resting always unconformably upon it; 
the secondary rocks are also very imperfectly developed, the mountain 
limestone being absolutely wanting, and the only indications of 
beds newer than the coal measures being a red conglomerate, into 
which they pass upwards. The flora of the coal measures is how- 
ever well known to be rich, and to have yielded near Radnitz the 
fossils described by Count Sternberg. A genus allied to Scorpio is 
* Impressions of shells were also found by the Author in a greyish sand 
rock, a little nearer Prague; and the Trinucleus is found at Zebrak and 
Praskoles, on the south side of the high road about 10 miles south of Beraun.
