It will no doubt be remembered by some that as far back as the year 1858, in“The Geologist,” Vol. I. pp. 480 and 509, I published a paper upon the Chloritic and Fossiliferous Marls, with some remarks on the Upper Greensand, of the Isle of Wight, my object being to point out the difference between these deposits, and their organic remains, with the view to their separation; stating as a reason that the fossils and deposits of the upper beds which intervene between the Chalk and the Upper Greensand were a distinct formation, and contained distinct fossils from those of the beds below.

But like much that has been written upon the subject, both before and since, the paper was no doubt defective, especially in the nomenclature of the fossils. Still, the main facts remained.
