A little south of Castor, the Lincolnshire Limestone is only thinly 

 shown; and a little further south, the Upper Estuarine and the 

 Lower Estuarine have once more come together, without the 

 intervention of the Lincolnshire Limestone, which has thinned away 

 and disappeared : the same phenomena are repeated at the opposite, 

 the Huntingdonshire side of the river, at Water Newton ; and here, 

 therefore, we may place the limit of the Eastern extension of the 

 formation. 



* Found also at Essendine and Danes' Hill, and near Northampton — all in 

 Great Oolite Limestone.
