GEOLOGY. 



The section of Purbeck strata exposed in Durdleston Bay, which 

 I published in 1852, ( see p. 9, ) was unavoidably incomplete. 

 I am now enabled to supply some of the measurements which 

 were then omitted. For the section of the Marble bands, I referred 

 to the one taken at Woody-Hyde Quarry, ( p. 8. ) which is 

 correct at that locality, but does not accord with the strata 

 developed at Peverel Point, where the following measurements 

 have been carefully taken by Mr. Lester.
