The Levenshulme Limestones. 351 



land surface, and that here no pre-Permian denudation of 

 the carboniferous rocks has taken place. 



Many tons weight of the limestone beds from Levens- 

 hulme have been conveyed to Brockhurst, where the 

 various horizons have been kept carefully apart, and are 

 available for future study ; the effect of frost, and weathering, 

 has disclosed many interesting fossil forms, which were 

 not at first apparent. The fish and possibly reptilian remains 

 are being studied by Mr. Wm. Davis, F.G.S., F.L.S., 

 of Chevinedge, Halifax ; the mollusca by Mr. Newton, 

 F.G.S., F.L.S., of the Geological Survey; and Professor 

 Rupert Jones, F.R.S., has undertaken the microscopic 

 organisms. 



Studying the fauna as a whole, it reproduces, in a 

 remarkable degree, the forms occurring in the Burdie 

 House Limestones, and points to a striking recurrence of 

 conditions, the one occurring at the commencement of the 

 Carboniferous Epoch, the other at its close. It is worthy 

 of note that the first appearance is in the more northern 

 area, just as coal seams and their attendant flora preceded 

 the deposition of the Carboniferous Limestones in the 

 South of Scotland ; in the North of England they only 

 appear in the millstone grits, while in the South of England 

 the latter are called the Farewell Rocks, the coal seams 

 only coming in the true Coal Measures overlying. It is of 

 interest, also, to note, that in the Arctic regions the coal 

 seams of the " Ursa Stage " are older than the Car- 

 boniferous Limestones, and are about equivalent to the 

 Burdie House series. 



The recurrence of these early conditions is most marked 

 in the Ardwick and Levenshulme series, where many 

 microscopic slides of the limestone are undistinguishable, 

 in the character of the minute fauna, from the forms present 

 in those from Burdie House. 



It is a source of satisfaction to bring before the Society
