TRANSACTIONS OF THE SECTIONS. 103 
shells. At the same level (twenty-five feet above ordinary spring- 
tides) a mixed mass of fine gravel sand and shells ( Tedlina solidula, 
Littorina communis, L. neritoidea, Patella vulgaris, but no extinct 
species ). 
2. A double range of terraces and declivities, the upper one most 
conspicuous, which appear to correspond to the strikes of the shale and 
limestone beds, which form in this hill the base of the limestone series. 
On the upper of these, shells of the kind already noticed were found 
by digging to the depth of a foot. 
3. A remarkable broken part in the brow of the upper terrace or 
inner cliff, already mentioned, a fact inexplicable by modern agency, 
but easily understood as the effect of an ancient slip, produced by 
littoral action. 
From these phenomena, combined with a careful survey of the geo- 
graphical features of the vicinity, the author states his conclusion to be 
that convincing evidence exists, that at some distant period since the 
complete establishment of the present order of animal life, an elevation 
to the extent of twenty or thirty feet has occurred along the northern 
coast of Woodspring-hill ; and that there is also a probability that a 
similar movement happened at some previous date, yet still within the 
modern geological period. But although a connexion between the 
event here described and the minor movements of the district, to which 
allusion has been made, may be suspected, yet the author is unable to 
trace such relationship from want of knowing what common evidence 
of former position can exist under such varying conditions as are 
implied by inland situation on the one hand, and on the other, close 
contact with the sea-shore.

On the Older Strata of Devonshire. By the 
Rev. Davin WituiaMs, F.G.S. 
The author stated that certain fossils had been discovered in the 
culm and plant rocks in the neighbourhood of Exeter by Mr. Parker, 
jun., of genera and species such as had not hitherto been found in any 
part of the true coal measures of England. Mr. James Sowerby had 
kindly examined them, and determined “five species, viz. Nautilus 
subsulcatus, Goniatites spirorbis, G'. reticulatus, G. striolatus, and G. 
Calyx, all figured by Phillips.” Mr. Sowerby stated that there were 
about ten other species, and a Zurbo or Littorina. Mr. Williams con- 
tended that these reliquiz, coupled with the diametrically contrasted 
mineral characters of the floriferous series of Devon, showed that they 
could not be the true equivalents of the English coal-field. In con- 
firmation of this he appealed to the organic remains of Petherwin and 
Landlake, which he included beyond any doubt in the lower culm 
measures, and of which Professor Sedgwick and Mr. Murchison, in the 
London and Edinburgh Philosophical Journal for April, 1839, had 
stated that there was “an unequivocal passage between those fossilife-
