manufacturers had for rendering assistance to this society 
was very obvious. (Without the numerous sections exhi- 
bited we cannot give more than a minute outHne of this 
interesting paper.) Tlie Stanley seams, as occupying the 
highest position in the district, were first minutely described. 
These seams are worked at Hatfield Colliery, Auchthorpe 
Colliery, and the Victoria Colliery ; the seams are usually 
17 yards apart ; the upper seam is 2ft. 6in. thick, the under 
one very variable, and composed of three or more beds 
separated by argillacious bands. The next section was at 
Whitwood, east of Stanley. The strata here were compared 
with those at Stanley, and the similarity fully established ; 
but there was here another deeper bed. At Wrenthorpe 
the sinking of the shaft was commenced just at the out- 
break of the Stanley Main Coal, and continued to a depth 
of 186 yards. This shaft passed through the Whitwood 
Lower Coal, and also the Haigh Moor Coal. By the 
Newmarket section, the Lofthouse coal was proved to be 
the same as the Haigh Moor ; and that the lower seam at 
Whitwood, the middle seam at Wrenthorpe, and the 
Warrenhouse coal at Newmarket were also identical. The 
northern outbreak of the Lofthouse coal was traced from 
Rothwell to Ardsley, and the fact insisted on of the occurrence 
a few hundred yards beyound that outbreak, of a peculiar 
yellovnsh sand-stone rock, commonly called the Quarry- 
stone. This is called by Dr. Smith the Bradgate Rock, but 
Mr.Sharp has proved that the Bradgate Rock is much deeper. 
The Thornhill Lees or Middleton Rock was given as more dis- 
tinctive. In two sections of strata below the Haigh Moor Coal, 
Mr. E. pointed out the situation of this rock, and thus fixed its 
position with regard to the old and inferior seams. He 
likewise compared their section with the Middleton section, 
and assigned the position of the Fish Coal and the 40 yards 
coal ; the former seam being 80 yards below the Haigh Moor 
Coal. The roof of the Fish Coal consists of bituminous 
shale 6 inches in thickness, from which nearly the whole of 
the specimens described by Mr. Teale were obtained, A 
remarkable fact of the thinning away of Sandstone was 
mentioned. Tw© of the Middleton pits are 300 yards apart ; 
in cne, the Quarry stone or rock is 16 yards thick, in the 
other only 2 ; although the depth from the surface to the 
1st seam is the same at both pits. Here followed a des- 
cription of the yard coal at Middleton, the Main Coal, the 
11 yards coal, and lastly the Beeston Coal. The section at 
Beeston was similar to that at Middleton, Other seams are 
known to exist below the Beeston seam, but Mr. Embleton 
deferred a consideration of them to a future opportunity 
The following is the order of the seams, with the probable 
distances between them : —
