The Levenshulme Limestones. By William Brockbank, 

 F.L.S., F.G.S. 



{Received April 29th, 18 go.) 



The Railway cutting now in progress from Fallowfield 

 to Levenshulme has exposed a fine series of the Permian 

 red and mottled sandstones, clays, and marls, similar to 

 those referred to in the writer's communication printed in 

 the Society's Memoirs, Third Series, Vol. VIII. 



These beds have been carefully examined, at my request, 

 by Mr. C. E. De Ranee, F.G.S. , of H.M. Geological Survey, 

 who confirms the conclusions stated in that paper, the beds 

 shewing well-marked evidences of their Permian character. 

 Within 50 yards of Slade Lane the section shews the 

 junction between the Permians and the Upper Coal 

 Measures. This was not disclosed by the sewering operations 

 in Slade Lane, from which our previous knowledge was 

 derived, and it could not, therefore, have been shown in the 

 diagrams submitted to the Society in 1883. The line of 

 sewer ran along the face of the outcrop of the limestones, 

 and from this into the Permians, thus leaving its actual 

 position in doubt. The interesting point of junction was 

 discovered by Mr. De Ranee, who at once recognized it from 

 having seen exactly similar beds at Prescot, where they 

 were found to contain fossils, which give them the name of 

 the " Modiola-Macadami " beds, and which undoubtedly 

 belong to the Upper Coal Measures. 



Mr. De Ranee has drawn up the following memorandum 

 describing this part of the section : " The soft current-bedded 

 red sandstone, probably the age of the Collyhurst sandstone, 

 seen in the Railway cutting from a point about 50 yards west 

 of Slade Lane to the Wilmslow Road at Fallowfield, exhibits
