MIDDLE CHALK—KENT.

The Melbourn Eock can be seen in the railway cutting north of 
Otford Station, but is much broken up, and the section is now 
somewhat obscure. It was clearer when seen prior to 1871 by Mr. 
Whitaker, who gave some account of it in 1872, with a sketch 
which is here reproduced. *

A small quarry just west of Chevening Park, and another 300 
yards north-west of Court Lodge Farm, near Westerham, also expose 
the Melbourn Eock. 
The quarry at Westerham Hill is in the Terebratvlina zone and 
must be near the top of the zone, for three well-marked layers of 
flint are seen here, two near the bottom, and one high in the face, 
which exposes about 35 feet of soft white chalk.
