Vol. 65.] GEOLOGY OF THE NEIGHBOURHOOD OE SEAEORD. 461 



Band marked the top of the Micraster cor-anguinum-Zone. These 

 bands were easily to be identified, and horizons could often be fixed 

 within a few feet, even in shallow exposures. 



With regard to the interpretation of the fault suggested by 

 Mr. 0. T. Jones, this involved considerable 1 Literal movement, and 

 the Author considered it to be a less simple explanation than his 

 own. Moreover, it implied a continuation of the fold, of which he 

 found no evidence, somewhere on the east side of the river. 



He would not, at that late hour, refer to other points suggested 

 in the discussion, and he thanked the Fellows for their kind recep- 

 tion of his paper.
