the depth of 90 feet : that in the neighbourhood of Northway, weak 

 brine springs have been discovered in the lias clay at the depth of 40 

 feet ; and likevs^ise on Defford Common. All these springs, Mr. Burr 

 remarks, range N. and S. and in a line with the brine springs of 

 Droitwich and Stoke Prior. Near Stoulton, five miles from Worcester, 

 is a small, brackish marsh. 



In conclusion, the author expresses his hopes, that surveyors, em- 

 ployed on similar investigations, will be induced to lay the results 

 of their field work before the Society ; and he acknowledges his 

 great obligation to Capt. Morsoom, the superintending engineer of 

 the line, for being permitted to make free use of all the geological 

 information, which he obtained during the discharge of his duties. 



A paper on " the Coast Section from "White Cliff Lodge, one mile 

 south of Ramsgate, to the Cliff's End, near the " Station Brig" in 

 Pegwell Bay, Kent," by Mr. John Morris, was afterwards read. 



The cliffs consist of the upper chalk for about f of a mile, and of 

 " the lower or sandy beds of the London clay " for the remainder of 

 the distance. A capping of superficial detritus, of rubbly chalk, chaUc 

 flints, and loam, extends the whole way. 



The principal object of the communication is to describe a series 

 of dislocations in the chalk, marked by shifts in a layer of tabular 

 flints. 



1. At 52 paces from the commencement of the section is a slight indication 



of a fault. 



2. 30 paces further the layer of flints is depressed at a fissure 4 feet.

within 8 feet of the beach, and it is in one place affected 

 by a fault of 1^ feet.

Close to fissures 1 and 2, are indications of parts of the bed of flint 

 not having been equally disturbed, as they preserve the same ho- 

 rizontal range, while the portions on each side are depressed : a si- 

 milar example of irregular movement occurs at number 5. Beyond 

 the fault 10, the cliff recedes, forming a small cove, produced, the au- 

 thor believes, by the action of the sea on a considerable disturbance 

 in the strata, the minor faults being always accompanied at the foot of 

 the cliff by a natural excavation or cave. 



Where the layer of flint re- appears, it is curved, and is afterwards 

 traversed by three faults producing unequal depression, one of which 

 is coincident with a vein of tabular flint ; . beyond the Preventive Sta- 

 tion is another depression of 5 feet, the upper part of the fissure being 

 filled with chalk rubble, sand and flint, and the bottom hollowed into 

 a cave 10 feet high, and from 15 to 20 feet deep. At 10 yards from
