462 MR. W. BINNEY ON THE DRIFT-DEPOSITS 



XXXV. A fev) Remarks on Mr. Hull's Additional Observa- 

 tions on the Drift -deposits in the Neighbourhood of 

 Manchester. By the President, E. W. Binney, F.R.S., 

 F.G.S. 



Eead January 12th, 1864. 



The author said he wished to make a few remarks on the 

 Lancashire and Cheshire Drift. In the year 1841 he first 

 attempted to class the Drift-deposits found in the neighbour- 

 hood of Manchester, in a small paper, with a map, which 

 he prepared for the Statistical Society of Manchester. In 

 that memoir he divided the foreign drift in the ascending 



order — 



(i.) Lower sand and gravel, 



(2.) TUl, 



(3.) Upper sand and gravel; 



and he described the more modern deposits found in valleys 

 (No. 4) as valley-gravel. 



This order he adopted in a paper read before the Man- 

 chester Geological Society on the 22nd December 1842, 

 " Notes on the Lancashire and Cheshire Drift, '' and 

 printed by that Society in their Proceedings of 1843. In 

 that paper, in treating of the upper beds of sand and gravel, 

 he says, " At Manchester it (the Higher Drift) is composed 

 of lower gravel, till, and sand and gravel, while at Hey- 

 wood and Poynton, near the base of the Pennine Chain, 

 the beds of sand and gravel are parted by several beds of 

 loam and clay.'^ 



Again, in speaking of No. 3 deposit, he says, ^^The 

 gently rising lands of the two counties are generally com- 

 posed of this deposit. It varies much, both in its composi- 

 tion and thickness. Near the sea, at Ormskirk, the Till is 

 sometimes found without it ; but as you proceed to the 

 east it makes its appearance, and gradually thickens until 

 it attains its greatest thickness near the base of the Pennine
