lias taken. At the end of the cutting farthest from Bath the 

 various beds, together with their thin wafer Hke partings of 

 clay, assume the thickness of seven feet, and are followed by 

 masses of impure concretionary limestones and marls passing 

 into blue clay, at the base of which a thin bone bed half 

 an inch thick immediately underlies the metals. A very fine 

 fault to the soiith-east brings down the lower beds of the 

 lime series to the base of the cutting. 



The dip of the white lias to the north-west of the fault is 

 6" south by west, but owing to the disturbances which have 

 caused the downthrow of the upper beds, the same beds on 

 the opposite side dip at an angle of 20" in a similar direction ; 

 the width of the fault from shoulder to shoulder of white 

 lias is 106 feet. 



In the last Summary, mention was omitted to be made of a 

 Walk by the Club on the 2nd July, 1867, to Battle Field 

 the residence of A. C. McDougall, Esq., for the purpose of 

 inspecting two tumuli on that gentleman's property. A veiy 

 hospitable reception awaited the Members after a damp 

 traverse along the eastern outcrop of the oolite. The tumuli 

 appear to have been already examined, so that it is doubtful 

 whether they would repay the expense and the labour of re- 

 opening. 



The words of Mr. Gerkie in his address as President of the 

 Edinburgh Geological Society will form a letting conclusion to 

 this summary. Speaking of the advantage of local efforts and 

 the benefits to the cause of science by Members bringing to 

 the Meetings notices of new facts and discoveries made either 

 by themselves or others, he says — " The ambition of a local 

 society should be to be distinguished by the amount of use- 

 ful work which it can do, being well assured that no such 

 work, no matter how local in its first aspect, can be honestly 

 done without adding something to the stock of knowledge, 

 and thereby advancing the cause of science."
