Describes the progress of the second boring to a depth of 1762 feet, 

 proving an unexpected thickness of Secondary rocks, and that water 

 cannot be there obtained by a deep well. It has shown the existence 

 of thick beds of gypsum. 



The " Geological lleport," by "W. Topley, notes corrections in 

 former reports from information obtained by the second boring. The 

 Coralline Oolite, 17 feet thick, was reached at 1769 feet. The U. and 

 L. Calcareous Grits are either absent or are represented by sandy cal- 

 careous shales. - W. T.

 The L. Lias and RhsDtic beds are faulted against the Dolomitic Con-

 several species are recorded from the L. Lias above. H. B. W.
