Great Northern Railway. 



Half a mile beyond the Belmisthorpe cutting, the Stamford and 

 Essendine Railway joins tbe main line of the Great Northern Com- 

 pany. The sections exposed in the cuttings of this line between 

 Peterboro' and Grantham have been rendered classical by their 

 description by Professor Morris in a Paper published nearly twenty 

 years ago in the Quarterly Journal of this Society* ; and which 

 Paper constitutes the only existing reliable record of tbese valuable 

 sections, long since covered up. 



In this long interval, some advance has been made in the know- 

 ledge of the geology of this part of England ; and, as additional 

 light has been thrown upon the character and sequential position 

 of the beds then described, I shall perhaps be justified in redirecting 

 attention to these sections, and, while adopting Professor Morris's 

 descriptions, in venturing to assign some of the beds to other forma- 

 tions than those to which he referred them. It must not be for- 

 gotten, however, that in his interesting article in the ' Geological 

 Magazine ' for March, 1869, Professor Morris indicated that the 

 views which he had formerly entertained had undergone much 

 modification f. 



By taking these sections in succession in a direction from south 

 to north, a very complete sequence of the beds (from the Oxford 

 Clay to the Lincolnshire Limestone inclusive) of this Midland part 

 of the country will be obtained ; and I shall endeavour to apply 

 them as one group of evidence as to what that sequence really is, 



* Nov. 1853. 



f As far back as tbe date of Professor Morris's Paper in 1853, Dr. Lycett 

 had arrived at the provisional conclusion that the beds now known as the 

 Lincolnshire Limestone were Inferior Oolite ; and even three years previously, 

 the Rev. P. B. Brodie, F.G-.S., in a paper published in the ' Proceedings of the 

 Cotteswold Field Club,' expressed an opinion that some beds of the limestones 

 of Lincolnshire should be classed rather with the Inferior than with the Great 

 Oolite.
