stone^ &c., from tlie coal series^ magnesian limestone^ and the 
waterstone of the upper new red. These fragments are of va- 
rious sizes, the largest being five tons in weight, and are min- 
gled together without any order of deposition : near the edge of 
the great fault they are larger and more numerous than in any 
other part of the till near Manchester. Those boulders, such 
as the granites, porphyries, and hard slate rocks, which do not 
occur in situ within 100 miles of Manchester, are mostly well 
rounded, and some are scored with strise and pohshed ; whilst 
those found in the neighbourhood, such as mountain limestone, 
&c. are less striated and polished, and many are quite angular. 
Although the boulders occur in the clay, without any distinct 
lines of deposition, there occurs at one point a deposit of fine la- 
minated silt and sand, ten or twelve inches thick, and about 
a yard from the bottom of the till, which is twenty-one feet 
in thickness, and rests on an uneven surface of lower new red 
sandstone, evidently water-worn ; and in some places holes two 
or three feet deep being found occupied by the till. 2. Lower 
new red sandstone ; composed of dark red sand, variegated by 
patches of a yellowish-drab colour ; its thickness is full forty 
yards j the main dip is to the S. W., at an angle of 16^ to 18°, 
but it has also a considerable inclination to the N. W. No fos- 
sil remains have been found in it. 3. The Coal Measures; con- 
sisting of a bed of salmon-coloured argillaceous shale, thu'ty feet 
thick, containing impressions of Neuropteris cordata, and many 
common coal plants. The coal measures were partly elevated 
before the deposition of the new red sandstone formation, but it 
is evident that the latter have been raised by forces which have 
subsequently elevated the coal measures, as the similarity of dip 
in both strata testifies. 
On certain Movements in the Parts of Stratified Rocks, by J. 
Phillips, Esq. E.R.S. 
Mr. Phillips stated that for many years the attention of geolo- 
gists had been called in a very essential degree to the internal
