TRANSACTIONS OF THE SECTIONS. 83 
with their iron-works at Middlesbrough being very large, they commenced, about 
four years ago, to sink a well or shaft for fresh water. The shaft was carried to 
the aan of 180 feet. The supply of fresh water being still not considered sufii- 
cient, a very large bore-hole was, about a year ago, commenced from the bottom of 
the shaft. A bore of 18 inches diameter has been put down to the present extreme 
depth of 1312 feet. The strata bored through form part of the pper New Red 
Sandstone or Trias formation, the same as those in which the deposits of rock-salt 
of Cheshire occur. The rock-salt was first pierced at a depth of 1206 feet, and 
has been found to form a bed 99 feet in thickness. This bed terminates in a sort 
of conglomerate, consisting apparently of salt and limestdne mixed together. 
The quantity and quality of the brine have yot yet been fully tested, but the 
following is an analysis of a sample from the yery light-coloured portion of the

It is as yet impossible to estimate the extent or area of this deposit. On the 
north we have, at Castle Eden Colliery, the coal-measures overlain by the Per- 
mian; and at Oughton boring, nearer to the Tees, the Trias has been bored into 
about 500 feet ; the Hutton coal-seam, at Castle Eden Colliery, being about 750 
feet below the sea-level, and the salt at Middlesbrough about 1250 feet. On the 
south side of the Tees the Lower Lias is soon met with, and capped by the Upper 
Tips gad Oolitic measures. These measures dip both to the south and north from 
the Tees. 
On the Equivalents of the Cleveland Tronstones in the West of England, 
By Cuarves Moore, F.GS, 
These rocks, with their contained ironstone bands, had been traced by the author 
from Lyme Regis to Yeovil and Bath. In mineral wealth they formed a marked 
contrast to those in the north of England; for where the ore was rich enough to 
work, it was not thick enough, and vice versd. 
On the Organic Contents of the Lead Veins of Allenheads, and other Lead 
Vems of Yorkshire, By Cuartes Moors, F.GS, 
The author, having in former papers called attention to the orgemisms he had 
met with in the mineral veins which traverse the carboniferous limestones of the west 
of England, had of late subjected those of Yorkshire to the same scrutiny. In 
certain veins and fissures in these he had detected numerous organic remains, washed 
into them by the action of later seas. The most remarkable of these was that of 
the New Rake vein, the clayey infilling of which was found to contain abundance 
of “ Conodonts ”—the small tooth- and comb-like bodies hitherto found only in the 
Upper Silurian bone-beds, which Dr. Pander had described as fish-teeth, but which 
Dr. Harley has since established to be of crustacean origin. 
Observations of Sir R. I. Murcutson upon the Permian Group of the North- 
west of England, in communicating the outline of a Memoir thereon by 
Prof. R. Harknuss and himself. 
The Permian rocks, or youngest Paleozoic deposits, which form a natural group 
characterized by community of animal and vegetable life, occur in various parts of
