51 ANNUAL MEETING OF THE SOCIETY. 



while, going down, as it did, upon the surface of a tenacious 

 mud, the fall has been very gradual and steady, and the 

 consequent disruption of the ground very small. Had the 

 gault underneath been in a very liquid condition, it would, 

 doubtless, at several points, have forced its way up through 

 the overlying chalk, and a geological phenomenon of a 

 totally different nature would have presented itself. As it 

 was, the enormous weight of this vast body of chalk produced 

 a pressure on the gault beneath, which could be relieved only 

 by a giving way at the point of least resistance, which in this 

 case happened to be the place where the gault comes to the 

 surface, at and near low water mark. Here, therefore, the 

 internal pressure has come into play, with the result of 

 throwing up the ridge, of which I have spoken, along the 

 shore. But observe, that, to produce this ridge, pressure and 

 therefore motion, must have been propagated through the 

 mass underlying the seaward hills and slopes of the Warren ; 

 and here I should be inclined to think that the next great slip, 

 must occur. Meanwhile let the S.E.R. Co. look to it, for 

 one part of the present slip is within 1 5 feet of their em-, 

 bankments.

 the Rev. C. L. Acland, with specimens of aquatic life, both 

 animal and vegetable ; and a very beautiful bank of wild 

 flowers gathered and arranged by Mrs. Fixz Gerald.
