‘¢On the Chronological Value of the Triassic Rocks of Devonshire.’ 
By Mr Witutam Pencetty.—The red rocks of Devonshire are eminently 
detrital, and consist of conglomerates, sandstones, and marls, and belong 
to the Bunter or Lower Trias. They occupy the whole of the country 
east of a line from Torbay to Porlock in West Somerset. The general 
dip is about 153 degrees in the direction N. and 443 degrees E. (true), 
so that, judging from this horizontal extension in this direction, their 
volume must be enormous. The conglomerates and sandstone, in every 
layer, afford evidence of their littoral origin, and of their having been 
deposited on a tidal strand undergoing slow subsidence.

“On Coal in the Red Measures.’”” By Martuias Dunn, Government 
Mine Inspector.—After noticing generally the Cumberland Coal-fields and 
the New Red Sandstone, Mr Dunn said—lI have been led to form the idea 
that the Red Sandstone is but the superior strata of the coal field, and 
that the neighbouring coal seams will be found underneath; and judging 
from the flatness of the country around Silloth Harbour, I have assumed 
that the bottom of the basin will exist in that quarter, for appear- 
ances of a coal outcrop exist in the neighbourhood of the Oriffle moun- 
tains in Kirkcudbright. In pursuance of this theory, I assume that the 
coal-field of Canobie is similarly circumstanced, for the Red Sandstone 
there crops out contiguous to the pits, and the nature of the various seams 
of coal assimilate closely upon those of Cumberland. Another corre- 
sponding fact attends the colliery of Kirkhouse belonging to the Earl of 
Carlisle, although a portion of it also contains coals belonging to the 
Limestone formation.

‘On the Deposit of the Gravel, Sand, and Loam, with Flint Imple-

fruits of geological investigation was to invest almost every point on the 
earth’s surface with anew interest. The small French village named had 
long been remarkable for the school of the Jesuits established there; but 
antiquarians had discovered that it was near a burial ground of great 
antiquity. In the course of excavation there were discovered the graves 
of people far more ancient than any known to have been buried there. 
Other memorials were also discovered ; and on one he had obtained from 
the workmen he read the name of Constantius. A stone coffin was found,
