At Heaton Mersey the following section was met with : 
* Feet. 
Trias 45 
Permian — Red and variegated marls containing 
limestones 129 
Lower new red sandstone grooved . . 402 
576 
The Permian beds were cut off by a fault near the railway 
station at Heaton Norris, first shown to me by Mr. Hull, 
13. A., F.G.S., 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 that Mr. Howard’s sand delf is a 
likely place for ascertaining the existence of a coal field under 
the town of Stockport worth working. 
The next was a section made by Mr. John Wood, at Med- 
lock Vale, between 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 lime- 
stone and five 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 bo met 
with to enable us to determine the value of the great tract of 
coal measures lying between Ashton-under-Lyne, Oldham,
