416 MM. Wilson and Quilter — Rhcetic Section at Wigston. 



section at Wigston, near Leicester, which exhibits, not only the 

 whole thickness of these beds, but also clearly shows their relation- 

 ship to the overlying Lias and underlying Triassic rocks, and which 

 for an inland section must therefore be considered as quite unique 

 in this country. 



At the large brick and tile works of Messrs. Healey & Co., close 

 to the new London and N. W. Eailway Station of Glen Parva (about 

 four miles south of Leicester), the Ehgetics are exposed in two 

 contiguous clay pits, both of which are in work at the present time. 

 The more westerly of these pits — the one we purpose specially to 

 refer to, and of which we give a detailed section — shows, Keuper 

 marls 30 ft. succeeded by Ehastic shales 40 ft., and Lias limestone 

 1ft., with a capping of Boulder-clay which varies at the expense of 

 the underlying rocks from 8 to 27 feet in thickness.
