zones in the Coralline Crag proposed by the late Sir J. Prestwich, 

 but without success. J^o evidence was offered by Prestwich, except 

 of the most general character, and the features which he regarded 

 as characteristic of certain zones were equally applicable to others. 

 The evidence of the foraminifera did not seem to the Author of 

 much weight. "With few exceptions the Crag forms were world- 

 wide in their present distribution, and went back to older Tertiary, 

 Mesozoic, or even Palaeozoic times. Quoting from the list published 

 by Mr. Burrows and his colleagues, he showed that the forms 

 regarded by that writer as characteristic of certain zones were 

 equally common in Zone D at one place, in E at another, and in 

 F or G at a third. iSTo attempt had been made to work out the 

 supposed zones stratigraphically, nor was it possible to do so.
