But, at the pointnamed, about 50 yards west of Slade Lane, the base of thebright red sandstone is seen resting on, apparently, aneroded surface, sloping westward at io°, of green and deeppurple marls, and purple dark grits. These beds overlieseveral beds of the Levenshulme limestones with Spirorbiscarbonarius and a band of calcareous ironstone, at thelowest point yet reached, which are, in my opinion, theArdwick series of the Upper Coal Measures. They dipat a much higher angle than the overlying red-beds,which may indicate the presence of a fault, as suggestedby Mr. Brockbank in C & Oe Rance. Delt a. Boulder Clay. b. Drift Sand. c. Current-bedded red sandstone. Permian. d. Purple and green marls, and fine purple grits, resembling the Modiola- Macadamibeds of Sutton, near St. Helens. e. The Levenshulme Limestones, probably the Ardwick Limestones of the Manchester Coal-field. The cutting at Slade Lane has laid bare the outcrops ofthe several bands of limestone described in 1883, the upperlimestone being flat bedded, from 2 to 8 in. thick, andplentifully mottled with circular greenish markings, whichare popularly known as fish eyes in other localities. Thelower seams are thicker, and contain great numbers offossils. The upper surfaces of the outcrop limestones werefound to be much eroded, and many glacial scratch markswere clearly seen upon them. Boulders of granites, green- The Levenshulme Limestones. 211 stones, brown hematite, and coal measure sandstones werealso found lying im
