Since the Government Geological Survey of the country around Nottingham was made in the year 1859, and the Explanation on the Geological Map Quarter-sheet 71 N.E. was written in 1861, papers by local geologists have been written, stating that in the neighbourhood of Nottingham a perfect conformity existed between the Magnesian Limestone and the New Red Sandstone. This being totally at variance with conclusions I came to when I surveyed that country, I have been for some time past desirous to say a word on the subject, but being deeply occupied with the old rocks of the Lake district, I have put it off from time to time. I felt little doubt in my mind, when surveying the neighbourhood of Nottingham, that there was a considerable break between the Magnesian Limestone and the New Red Sandstone, and this opinion was completely confirmed as I continued my survey northwards through Nottinghamshire into Yorkshire.
