with a bed of limestone half-way down, were attributed by Andrews 

 to the Coal-measures, showing an attenuation of the Trias in this 

 direction. At Combe Abbey to the south, however, 180 feet lied

 Marl, probably Permian or Upper Coal-measures. At Brandon, south- 

 east of this, the section was —

 This shows an attenuation of the waterstones to the east. At 

 Cops wood Grange, near Stoke, there were 60 feet Keu[)er Marl, 

 82 feet grey waterstones, 97 feet brown and red sandstones, showing 

 a thickening of the middle series again to the west. 



(4) Charnwood Forest District. 



The Charnwood range is circumscribed by the Leicester and Burton 

 line, the Lotighborou'.'h and Coalville line, and the Loughborough 

 and Leicester line. Since the last runs to the west of the Triassic 

 outcrop on the east, this area is not strictly included within the last 

 boundary, and the outlying tracts are here included up to the Tea- 

 green Marls. 



A feature of this area is the unusual manner in which the Trias 

 reposes against the older rocks, seen to some extent in proximity to 

 the southern syenites of Croft, etc., but better displayed with the 

 usual radial dip in this area. There is little or no necessity to 

 enlarge on these features, as Professor Watts and T. 0. Bosworth 

 have done so elsewhere, with a diiferent interpretation of these 

 features. It is not the purpose of this paper to enter into discussion 

 as to the causes of these abnormal phenomena in the marls, but simply 

 to record their occurience. In doing this also features described, by 

 the foregoing authors will not here be referred to except where 

 a different account can be given in the light of fresli knowledge. 

 My views as to these phenomena have already been outlined in 

 abstract, unfortunately too brieflj- to adequately explain my 

 contentions, and a fuller account will be published shortly elsewhere. 

 This will obviate any special allusion to these matters of purely local 

 occurrence in this paper. In the nortli-west of this area tliere are 

 exposures of the Lower Keuper Sandstone, and though some writers 

 have stated that it does not encircle the Charnian rocks, yet there 

 are several points in this district where it undoubtedly does. 



The Red Marl reaches its liighest altitude in Britain here at Bardon 

 Hill, and throughout this district west of the Soar Valley rises generally 

 to a more or less uniform altitude of 500 feet on the west down to 

 300 feet on the east. Owing to the contact of the Red Marl with the 

 older rocks numerous opportunities of studying it are presented, of
