Ordinary Meeting, February 8th, 1870. 
J. P. Joule, LL.D., F.R.S., &c., President, in the Chair. 
E. W. Binney, F.R.S., F.G.S., said that in Vol. III., page 
14, of the Society’s Proceedings, he had noticed the occur- 
rence of stray boulders without traces of clay, high up the 
western slopes of the Pennine chain, and he described one at 
the extreme end of the valley of the Tame near New Year’s 
Bridge, above Denshaw, in Saddleworth. Many years since 
he had observed large blocks of greenstone without any clay 
or sand on Pikelow, to the east of Macclesfield. Both these 
places were about 1,000 feet above the level of the sea. Mr. 
A. H. Green, M.A., F.G.S., and his colleagues/ in their 
valuable memoir on the Carboniferous Limestone, Yoredale 
Rocks, and Millstone Grit of North Derbyshire and the 
adjoining parts of Yorkshire, just published by the Geo- 
logical Survey, after describing some stray boulders found 
by himself and Mr. Sorby, F.R.S., near Rotherham and Shef- 
field, at p. 133 says, “ Our knowledge of the portion of the 
eastern plain from Sheffield through Chesterfield down to 
Belper is meagre ; we believe we are right in representing 
as in the main free from drift, but whether any isolated 
patches or erratics are to be found in it we cannot say.” 
During a residence of five or six years he (Mr. B.) had often 
searched for these boulders in the neighbourhood of Chester- 
field. The only foreign rock which he met with in that district 
was a large block of greenstone several hundred pounds in 
weight. This he found above the valley of the Hipper near 
Spring Bank and below the Waterworks station, Chester- 
field. The stone was well rounded and polished. He men- 
tioned the fact to direct the attention of observers to this
