Peterborough to Sleaford 
The Cornbrash has been well exposed near Peterborough, and 
its fossils have been collected by J. F. Bentley and Dr. Henry 
Porter. It has been opened up in the railway-cuttings between 
Peterborough and Walton, and very fossiliferous beds were 
noticed on Ailsworth Heath by Prof. Judd, who there obtained 
Ammonites discus, Lima pectiniformis, &c. At Helptone he 
noticed the oyster-bed with Ostrea Jlabelloides, in the top layer 
of the Cornbrasli ; and he obtained large specimens of Ammonites 
macrocephalus (one example being 18 inches in diameter), and 
also quantities of fossil wood from the beds. Large Ammonites 
were also obtnined from a quarry near Uffington Lodge, together 
with other fossih--. The specimens of Waldheimia obovata include 
forms which here, as well as in some other localities, approach 
closely to TF. digona. Cuttings on the Great Northern Hallway, 
to the north of Casewick, showed fossiliferous beds of Cornbraeh, 
and these were originally described by Mcrri u .*
