Owing to the impossibility of making an accurate Survey of many of the flatter and Drift-covered portions of England, in the absence of sections, the light boring tools so extensively used by the Geological Survey of Belgium have been experimentally tried during the last few months in the Isle of Wight. The results arrived at are of so much interest that the Director has requested me to draw up this preliminary notice.The Hempstead Beds, which were thought to be confined to the outlier at Hempstead Cliff and another of unknown extent in Parkhurst Forest, prove to be much more important, indeed they occupy about half the Tertiary area of the Isle of Wight.

Some new species having been found in the Isle of Wight during the lately renewed examination of its geology by the Geological Survey, and the known Wealden species of that island not having been hitherto so distinctly indicated as might be, it is thought advisable to give some notes on, and a resume of, this interesting series of fossil species.


In 1863, Heer and Pengelly published in the ‘Phil. Trans.’ an account of these lignite-beds and their flora. Heer classed the lignite as Lower Miocene, considering it equivalent to the Aquitanian of Prance and to the Hamstead Beds of the Isle of Wight. These latter are now referred to the Middle Oligocene, and many of the other deposits called Lower Miocene in Heer’s day are now classed as Upper Oligocene. A statement by Mr. Starkie Gardner, that Heer’s Bovey plants are the same as those found in the Bournemouth Beds (Middle Eocene), has caused the Bovey Beds to be classed as Eocene in recent text-books and on recent maps of the Geological Survey, leaving a great gap in the geological record in Britain. Every division, from Upper Oligocene to Upper Miocene, was supposed to be missing.
