Thick and Thin, and still further on these seem to run together and 
form the valuable seam of the Haigh Moor. They hold about the 
same position as the Swallow Wood, and may prove to be the same 
coal. The succeeding measures are traced up to the Shafton Coal, 
and the red rock of Rotherham was described. This was referred by 
Prof. Sedgwick to the marls and sandstones beneath the Magnesian 
Limestone generally as the Rothliegendie. Fairey, Thorp, and other 
local Geologists looked upon it as a regularly interbedded sandstone 
of the Coal Measures. Mr. Green was of opinion that it was a mem- 
ber of the Coal Measure Series, but unconformable with the strata 
composing the coal formation. After the main mass of that formation 
had been deposited, upheaved, and denuded, the red rock and the 
beds overlying it were laid down upon the truncated edges of the 
previously-formed strata, so that these latter rocks rest sometimes 
on one member, sometimes on another, of the older Carboniferous 
series. He further considered that the problem of the red rock 
of Rotherham was by no means solved, and was one to which local 
observers would do well to turn their attention. A paper was read at 
the same meeting on the nature of the Graptolitid?e, with notes on 
the British genera by Dr. H. Alleyne Nicholson, of Keighley, which 
was not published. 
At a meeting held in April, 1869, at Wakefield, the statement 
of receipts and expenditure for the year ending October, 1868, was 
presented. The total income was £64 7s. Od. The principal items 
of expenditure were for printing, £18 19s. Od. ; Rent of Museum 
Rooms at the Philosophical Hall, £10 Os. Od. ; and Assistant Sec- 
retary, on account, £26 8s. 6d. ; which togetJier with smaller items 
absorb the whole. Messrs. J. G. Marshall and T. W. Embleton were 
re-appointed Honorary Curators of the joint collections of the Philo- 
sophical Society and the West Riding Geological and Polj^technic 
Society. 
A number of natural pits in the valley of tlie Ure, near Ripon, 
formed the subject of a paper by the Rev. John Stanley Tute, of 
Markington. They occur in an area of about a square mile, on the 
north-east side of the city, and consist of crater-like hollows from 
50 to 100 feet across, and sometimes with large and perpendicular
