xJeING resident in a district which has been but little noticed 

 as to its geological structure, I have draw^n up the following re- 

 marks on its stratification ; and though omissions may occur, yet I 

 trust that an account of the Wolds of Lincolnshire and the adjacent 

 country, may not prove uninteresting to the members of the 

 Geological Society. 



In conformity to the request of the Rev. Mr. Buckland, Professor 

 of Mineralogy in the University of Oxford, I have endeavoured to 

 trace on the annexed map, PI. 24. fig. 4. the denudations or bassets 

 of the chalk, the oolite limestone, and the sand strata, together 

 with the alluvial earth and hills of the same formation, with as 

 much accuracy as my personal knowledge and the nature of the 

 country will admit. I have also added a sketch of a section, 

 PI. 24. fig. 3. on the same scale as the map with respect to hori- 

 zontal distance (the elevation being merely imaginary) intended to 

 elucidate the order of the stratification.
