Owing to the destruction of the fossils it is impossible to fix the limits of 

 the different beds in this boring. The " sand " in the old well is the bed 

 at the base of the Middle Hamstead Beds, The"limnaean limestone " is 

 apparently the Bembridge Limestone. The boundary between the Osborne 

 and Headon beds is quite uncertain.
