Near Leicester the sandstone is uniformly false-hedded from the south-west, 
and Estheria and fish-scales occur upon the false-hedding planes. Heavy mineral 
separations have been prepared from a large number of localities throughout the 
country. The mineral grains are generally very much worn. ‘he most plentiful 
are garnet, magnetite, zircon, tourmaline, and rutile. 
In the normal Keuper Marl, bands showing false bedding, ripple marks, and 
salt pseudomorphs are generally common, but such evidence of sub-aqueous deposi- 
tion as there is points rather to the existence of occasional streams and salt pools 
than to the deep waters of one great Keuper lake. 
It is inferred that the Upper Keuper is a desert accumulation. 
5. The Relation of the Keuper Marls to the Pre-Cambrian Rocks at Bardon 
Hill. By W. Keay and Martin Ginson. 
Bardon Hill is situated in the Charnwood Forest area, about ten miles north- 
west from Leicester. The hill rises to an elevation of 912 feet, and is higher than 
any of the land intervening between this point and the German Ocean. 
The hill consists of Keuper marls resting unconformably upon Pre-Cambrian 
rocks, the latter protruding about 100 feet through the marls. 
The object of this paper was: (1) To remark upon the unusual elevation of 
the Keuper marls; (2) To consider the probability of the entire submergence of 
the hill during the Triassic period. 
1. Elevation.—Acting upon a statement of Professor Phillips that ‘the 
Triassic system offers the remarkable fact of never rising to elevations much above 
800 feet,’ the authors by personal inspection, where possible, and by the aid of 
ordnance levels, failed to discover any point on the Trias in England reaching a 
greater height than 800 feet except at Bardon Hill. Here, ‘skerry’ bands in 
the Keuper marl may be seen at a height of 810 feet, and the marl may be traced 
in the fissures of the Cambrian rocks to a height of 880 feet. Ilence the con- 
clusion that the Keuper marls at Bardon reach an elevation at least as high, and 
possibly higher than at any other point in the same strata in England. 
2. Submengence.—The probability of Bardon Hill (912 feet), and therefore the 
whole Charnwood area, being entirely submerged during Triassic times presents 
itself as a problem. 
The authors found at 810 feet two distinct ‘skerry’ bands resting upon, and 
overlain by, Keuper marl. In the Siberia Quarry the marl is found filling in two 
joints which rise nearly vertically a height of 80 feet. This ‘filling’ may be 
traced in the joints to a level of 880 feet, or 32 feet below the summit of the 
hill. There is no evidence suggesting the sudden termination of the marl at this 
level, but further tracing was prevented by vegetation. It is obvious that the 
marl must have been deposited trom an elevation higher than 880 feet, 
Further evidence in support of submergence was offered as follows: The 
general dip of the marls in this district is from 1° to 38°S.E. Allowing an 
inclination of 1° only, or 90 feet per mile from a point at the junction with the 
Rheetics near Leicester, this would give (on the assumption that this inclination 
originally extended to Bardon) a covering of over 200 feet of marl above the 
present hill. 
6. On a Peculiarity in the Mineralogical Constitution of the Keuper Marl. 
By C. Ginpert Cutis, D.Se., F.G.S. 
It has often been proved that the Keuper marl is, in places, markedly 
calcareous; but little has hitherto been done to show in what mineralogical 
form the calcareous matter exists in such cases. To determine this an investiga- 
tion was made, and the results obtained, together with a suggestion as to their 
significance, are here recorded. 
Most of the specimens examined were taken from the well-known cliff-section 
at Westbury-on-Severn, about eight miles S.W. of Gloucester. Treatment with
