a similar dip. These last-named strata were overlapped by the Trias, 
which dips to the south-west at an angle of 12^. 
At Heaton jVIersey the following section was met with: — 
Feet. 
Trias 45 
Permian — Red and varigated marls containing hmestones 129 
Lower New Red Sandstone grooved 402 
576 
The Permian beds were cut off by a fault near the railway station at 
Heaton ]S orris (first noticed by IMr. Hull, of the Geological Survey), which 
brought in the Trias. This rock occupied the district between that town 
and Goyt's Hall, in the Marple valley, where the lower part of the middle 
coal-measures was seen in nearly a vertical position. 
The author considered Mr. Howard's saud delf to be a likely place 
for ascertaining whether a coal-field worth working existed under the 
town of Stockport. 
The next was a section made by Mr. John AYood, at Medlock Vale, be- 
tween Waterhouses, near Ashton-under-Lyne, and Manchester. It was 
as follows : — 
Feet. In. 
Drift 26 0 
Trias 23 0 
Permian — Red marls, with beds of limestone and tive beds of 
gypsum 246 3 
Lower New Red Sandstone 375 11 
Coal-measures about 90 0 
761 2 
What these coal-measures were, whether above or under the Bradford 
Four-feet Mine, it was at present impossible to say ; but it was to be 
hoped that some mine would be met with to enable us to determine the 
value of the great tract of coal-measures lying between Ashton-under- 
Lyne, Oldham, Middleton, and Manchester. Mr. Wood had done more 
than any other gentleman to clear up this point, and it was to be desired 
that he should meet with a good seam of coal, both for his own sake and 
that of the public. 
The third section mentioned was at the sugar- works of Messrs. Fryer 
and Co., in Chester Street, Chorlton-on-MecUock, Manchester. The fol- 
lowing beds were there met with : — 
Feet. 
Trias 114 
Permian — Red marls with limestones 237 
Coarse red sandstone with pebbles 45 
Coarse red sandstone 24

wick) ^ ; 126

The limestones in the last-named strata contained specimens of Mici^o- 
conchies carbonarius and scales of Palceoniscus, which clearly proved them 
to be similar beds to those of the upper coal-field at Ardwick, to which 
they bear every resemblance in physical character. 
The occurrence of coal-measures on the south side of the city of Man- 
chester is quite new and of great importance, showing that such strata at
