fourth bed is more easily attainable, and is superior in quality as a 
building stone. Stretching northward from the extreme point of 
Cloud, at a much lower level, we have the Yoredale series of rocks, 
so named from a locality in Yorkshire. This section of the Car- 
boniferous system lies immediately below the grits, and it exhibits in 
this neighbourhood thin-bedded and coarse-grained sandstones, with 
dark shales, and occasionally thin earthy limestones. ‘This series 
enters into the composition and structure of the long ranges of 
Bosley Minn and the Gun ; also the sharp anticlinals of Biddulph 
Moor, besides, according to Messrs. Hull and Green, embracing at 
intervals, when not overlain by the Millstone-grit and Coal-measures, 
an extent of country from Cloud to Cheadle, near Alton, to Harting- 
ton in Derbyshire, and to Hayfield in the same county, and also to 
Marple, near Stockport. ‘These rocks reappear near Stalybridge ; 
and northward, in the Saddleworth valley, their thickness is not less 
than 2,000 feet. In the neighbourhood of Macclesfield, where I am 
pretty well acquainted with the deposits, the Yoredale series have 
thinned down about 800 feet. There also the first bed of grit is 
about 100 feet in thickness ; the second bed, 150; third, 200; fourth, 
100; fifth, 60: and add to these 400 feet for their intervening 
shales, we have a total thickness of 1,000 feet. I have now given 
you a short abstract of the different beds of grit, &c. as they relate 
more especially to the locality we have visited to-day. If we had been 
favoured with more time, and had extended our ramble to Rushton, 
there is a much wider field of interest and exploration at that place. 
For along with those beds of grit (excepting the first and third) and 
the Yoredale rocks, there are to be seen and studied some outliers of 
tlie Permian marls and sandstones, and the pebble-beds-of the Bunter 
series.’ —J. D. S. 
Tue WARRINGTON Fietp Naruratists’ Society held their Third 
Annual Meeting atthe Mechanics Institution, on the evening of May 
10th, under the presidency of T. G. Rylands, Esq., F.L.S., &c. 
Mr. Greening, Mr. Milner, Mr. Green, and many other gentlemen, 
exhibited microscopes and objects of Natural History; and papers 
were read by Mr. Peers, the Honorary Secretary, and by Mr. Green. 
Mr. PATERSON read an exceedingly interesting paper on the Geo- 
logy of the District. After describing the position of the New Red 
Sandstone formation (to which the rocks immediately surrounding 
us belong), he stated that the Permian may be seen in a cutting on 
the Manchester and Liverpool Railway, where it is crossed by the 
St. Helen’s and Runcorn Gap line. Itappears to form a belt, about 
half a mile in width, from the Grange, north of St. Helen’s station, 
in the direction of Parr and Sutton Mill, and on to Rainhill, where 
it is thrown out by a fault. Pebble-beds occur in the same neigh- 
bourhood: a deposit may be seen in an old quarry by the roadside 
at Winwick, in a dell between Newton Heath and Harlestown vil- 
lage; also at Newton and the railway cuttings to the east. In an 
industrial point of view, these beds may be regarded as the most 
valuable in the Triassic series, the stone being comparatively hard,
